Dynamically updating column value in SQL - sql

I am passing one password value for either 2 or 3 or 4 or 'n' number of usernames.
How to pass the user_id dynamically to the update query ?
update user_table
set column_password = 'password value'
where user_id in ( )


First create the function using this code:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE FUNCTION [dbo].[SplitIDs]
(
#List varchar(5000)
)
RETURNS
#ParsedList table
(
ID int
)
AS
BEGIN
DECLARE #ID varchar(10), #Pos int
SET #List = LTRIM(RTRIM(#List))+ ','
SET #Pos = CHARINDEX(',', #List, 1)
IF REPLACE(#List, ',', '') <> ''
BEGIN
WHILE #Pos > 0
BEGIN
SET #ID = LTRIM(RTRIM(LEFT(#List, #Pos - 1)))
IF #ID <> ''
BEGIN
INSERT INTO #ParsedList (ID)
VALUES (CAST(#ID AS int)) --Use Appropriate conversion
END
SET #List = RIGHT(#List, LEN(#List) - #Pos)
SET #Pos = CHARINDEX(',', #List, 1)
END
END
RETURN
END
GO
then in your stored procedure declate #UserIDs varchar(max). You will pass comma separated ID list into this param.
Then in your Stored proc you can have:
update U
set U.column_password = 'password value'
FROM dbo.SplitIDs(#UserIDs) I
INNER JOIN user_table U ON I.ID=U.user_id


CREATE A Function
CREATE FUNCTION [dbo].[FnSplit]
(
#List nvarchar(2000),
#SplitOn nvarchar(5)
)
RETURNS #RtnValue table (Id int identity(1,1), Value nvarchar(100))
AS
BEGIN
While(Charindex(#SplitOn,#List)>0)
Begin
Insert Into #RtnValue (value)
Select Value = ltrim(rtrim(Substring(#List,1,Charindex(#SplitOn,#List)-1)))
Set #List = Substring(#List,Charindex(#SplitOn,#List)+len(#SplitOn),len(#List))
End
Insert Into #RtnValue (Value)
Select Value = ltrim(rtrim(#List))
Return
END
Store Procedure
CREATE Procedure usp_Multipleparameter (#Users VARCHAR(1000)= NULL)
AS
BEGIN
update user_table
set column_password = 'password value'
where user_id collate database_default IN (SELECT Value FROM dbo.FnSplit(#Users,','))
END
GO
Calling Store Procedure
EXEC usp_Multipleparameter 'User1,User2'


Just a thought. If this is already in a stored procedure it is likely you already have the user_id available to you through a select statement. I would do something like this.
update user_table
set column_password = 'password value'
where user_id in ( select user_id from table
where criteria = '' )

Dynamic SQL Comma Delimited Value Query

I have a SQL Server Stored Procedure where I would like to pass a varchar full of comma delimited values to an IN function. For example:
DECLARE #Ids varchar(50);
SET #Ids = '1,2,3,5,4,6,7,98,234';
SELECT *
FROM sometable
WHERE tableid IN (#Ids);
This does not work of course. I get the error:
Conversion failed when converting the varchar value '1,2,3,5,4,6,7,98,234' to data type int.
How can I accomplish this (or something relatively similar) without resorting to building dynamic SQL?

Of course if you're lazy like me, you could just do this:
Declare #Ids varchar(50) Set #Ids = ',1,2,3,5,4,6,7,98,234,'
Select * from sometable
where Charindex(','+cast(tableid as varchar(8000))+',', #Ids) > 0

Don't use a function that loops to split a string!, my function below will split a string very fast, with no looping!
Before you use my function, you need to set up a "helper" table, you only need to do this one time per database:
CREATE TABLE Numbers
(Number int NOT NULL,
CONSTRAINT PK_Numbers PRIMARY KEY CLUSTERED (Number ASC)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
DECLARE #x int
SET #x=0
WHILE #x<8000
BEGIN
SET #x=#x+1
INSERT INTO Numbers VALUES (#x)
END
use this function to split your string, which does not loop and is very fast:
CREATE FUNCTION [dbo].[FN_ListToTable]
(
#SplitOn char(1) --REQUIRED, the character to split the #List string on
,#List varchar(8000) --REQUIRED, the list to split apart
)
RETURNS
#ParsedList table
(
ListValue varchar(500)
)
AS
BEGIN
/**
Takes the given #List string and splits it apart based on the given #SplitOn character.
A table is returned, one row per split item, with a column name "ListValue".
This function workes for fixed or variable lenght items.
Empty and null items will not be included in the results set.
Returns a table, one row per item in the list, with a column name "ListValue"
EXAMPLE:
----------
SELECT * FROM dbo.FN_ListToTable(',','1,12,123,1234,54321,6,A,*,|||,,,,B')
returns:
ListValue
-----------
1
12
123
1234
54321
6
A
*
|||
B
(10 row(s) affected)
**/
----------------
--SINGLE QUERY-- --this will not return empty rows
----------------
INSERT INTO #ParsedList
(ListValue)
SELECT
ListValue
FROM (SELECT
LTRIM(RTRIM(SUBSTRING(List2, number+1, CHARINDEX(#SplitOn, List2, number+1)-number - 1))) AS ListValue
FROM (
SELECT #SplitOn + #List + #SplitOn AS List2
) AS dt
INNER JOIN Numbers n ON n.Number < LEN(dt.List2)
WHERE SUBSTRING(List2, number, 1) = #SplitOn
) dt2
WHERE ListValue IS NOT NULL AND ListValue!=''
RETURN
END --Function FN_ListToTable
you can use this function as a table in a join:
SELECT
Col1, COl2, Col3...
FROM YourTable
INNER JOIN FN_ListToTable(',',#YourString) s ON YourTable.ID = s.ListValue
Here is your example:
Select * from sometable where tableid in(SELECT ListValue FROM dbo.FN_ListToTable(',',#Ids) s)

No Table No Function No Loop
Building on the idea of parsing your list into a table our DBA suggested using XML.
Declare #Ids varchar(50)
Set #Ids = ‘1,2,3,5,4,6,7,98,234’
DECLARE #XML XML
SET #XML = CAST('<i>' + REPLACE(#Ids, ',', '</i><i>') + '</i>' AS XML)
SELECT *
FROM
SomeTable
INNER JOIN #XML.nodes('i') x(i)
ON SomeTable .Id = x.i.value('.', 'VARCHAR(MAX)')
These seems to have the same performance as #KM's answer but, I think, a lot simpler.

You can create a function that returns a table.
so your statement would be something like
select * from someable
join Splitfunction(#ids) as splits on sometable.id = splits.id
Here is a simular function.
CREATE FUNCTION [dbo].[FUNC_SplitOrderIDs]
(
#OrderList varchar(500)
)
RETURNS
#ParsedList table
(
OrderID int
)
AS
BEGIN
DECLARE #OrderID varchar(10), #Pos int
SET #OrderList = LTRIM(RTRIM(#OrderList))+ ','
SET #Pos = CHARINDEX(',', #OrderList, 1)
IF REPLACE(#OrderList, ',', '') <> ''
BEGIN
WHILE #Pos > 0
BEGIN
SET #OrderID = LTRIM(RTRIM(LEFT(#OrderList, #Pos - 1)))
IF #OrderID <> ''
BEGIN
INSERT INTO #ParsedList (OrderID)
VALUES (CAST(#OrderID AS int)) --Use Appropriate conversion
END
SET #OrderList = RIGHT(#OrderList, LEN(#OrderList) - #Pos)
SET #Pos = CHARINDEX(',', #OrderList, 1)
END
END
RETURN
END

It's a very common question. Canned answer, several nice techniques:
http://www.sommarskog.se/arrays-in-sql-2005.html

This works perfectly! The below answers are too complicated. Don't look at this as dynamic. Set up your store procedure as follows:
(#id as varchar(50))
as
Declare #query as nvarchar(max)
set #query ='
select * from table
where id in('+#id+')'
EXECUTE sp_executesql #query

I can suggest using WITH like this:
DECLARE #Delim char(1) = ',';
SET #Ids = #Ids + #Delim;
WITH CTE(i, ls, id) AS (
SELECT 1, CHARINDEX(#Delim, #Ids, 1), SUBSTRING(#Ids, 1, CHARINDEX(#Delim, #Ids, 1) - 1)
UNION ALL
SELECT i + 1, CHARINDEX(#Delim, #Ids, ls + 1), SUBSTRING(#Ids, ls + 1, CHARINDEX(#Delim, #Ids, ls + 1) - CHARINDEX(#Delim, #Ids, ls) - 1)
FROM CTE
WHERE CHARINDEX(#Delim, #Ids, ls + 1) > 1
)
SELECT t.*
FROM yourTable t
INNER JOIN
CTE c
ON t.id = c.id;

I think a very simple solution could be following:
DECLARE #Ids varchar(50);
SET #Ids = '1,2,3,5,4,6,7,98,234';
SELECT *
FROM sometable
WHERE ','+#Ids+',' LIKE '%,'+CONVERT(VARCHAR(50),tableid)+',%';

Without using dynamic SQL, you have to take the input variable and use a split function to put the data into a temp table and then join to that.

Thanks, for your function I Used IT........................
This is my EXAMPLE
**UPDATE [RD].[PurchaseOrderHeader]
SET [DispatchCycleNumber] ='10'
WHERE OrderNumber in(select * FROM XA.fn_SplitOrderIDs(#InvoiceNumberList))**
CREATE FUNCTION [XA].[fn_SplitOrderIDs]
(
#OrderList varchar(500)
)
RETURNS
#ParsedList table
(
OrderID int
)
AS
BEGIN
DECLARE #OrderID varchar(10), #Pos int
SET #OrderList = LTRIM(RTRIM(#OrderList))+ ','
SET #Pos = CHARINDEX(',', #OrderList, 1)
IF REPLACE(#OrderList, ',', '') <> ''
BEGIN
WHILE #Pos > 0
BEGIN
SET #OrderID = LTRIM(RTRIM(LEFT(#OrderList, #Pos - 1)))
IF #OrderID <> ''
BEGIN
INSERT INTO #ParsedList (OrderID)
VALUES (CAST(#OrderID AS int)) --Use Appropriate conversion
END
SET #OrderList = RIGHT(#OrderList, LEN(#OrderList) - #Pos)
SET #Pos = CHARINDEX(',', #OrderList, 1)
END
END
RETURN
END

If you use SQL Server 2008 or higher, use table valued parameters; for example:
CREATE PROCEDURE [dbo].[GetAccounts](#accountIds nvarchar)
AS
BEGIN
SELECT *
FROM accountsTable
WHERE accountId IN (select * from #accountIds)
END
CREATE TYPE intListTableType AS TABLE (n int NOT NULL)
DECLARE #tvp intListTableType
-- inserts each id to one row in the tvp table
INSERT #tvp(n) VALUES (16509),(16685),(46173),(42925),(46167),(5511)
EXEC GetAccounts #tvp

Its been a while but I have done this in the past using XML as a interim.
I can't take any credit for this, but I'm afraid I no longer know where I got this idea from:
-- declare the variables needed
DECLARE #xml as xml,#str as varchar(100),#delimiter as varchar(10)
-- The string you want to split
SET #str='A,B,C,D,E,Bert,Ernie,1,2,3,4,5'
-- What you want to split on. Can be a single character or a string
SET #delimiter =','
-- Convert it to an XML document
SET #xml = cast(('<X>'+replace(#str,#delimiter ,'</X><X>')+'</X>') as xml)
-- Select back from the XML
SELECT N.value('.', 'varchar(10)') as value FROM #xml.nodes('X') as T(N)

Create a table function like below which parse comma separated varchar and returns a table that can be inner joined with other tables.
CREATE FUNCTION [dbo].[fn_SplitList]
(
#inString varchar(MAX) = '',
#inDelimiter char(1) = ',' -- Keep the delimiter to 100 chars or less. Generally a delimiter will be 1-2 chars only.
)
RETURNS #tbl_Return table
(
Unit varchar(1000) COLLATE Latin1_General_BIN
)
AS
BEGIN
INSERT INTO #tbl_Return
SELECT DISTINCT
LTRIM(RTRIM(piece.value('./text()[1]', 'varchar(1000)'))) COLLATE DATABASE_DEFAULT AS Unit
FROM
(
--
-- Replace any delimiters in the string with the "X" tag.
--
SELECT
CAST(('<X>' + REPLACE(s0.prsString, s0.prsSplitDelimit, '</X><X>') + '</X>') AS xml).query('.') AS units
FROM
(
--
-- Convert the string and delimiter into XML.
--
SELECT
(SELECT #inString FOR XML PATH('')) AS prsString,
(SELECT #inDelimiter FOR XML PATH('')) AS prsSplitDelimit
) AS s0
) AS s1
CROSS APPLY units.nodes('X') x(piece)
RETURN
END
=================================================
Now consume above created table function in your code,creation of function is one time activity in your database that can be used across databases as well on same server.
DECLARE #Ids varchar(50);
SET #Ids = '1,2,3,5,4,6,7,98,234';
SELECT
*
FROM sometable AS st
INNER JOIN fn_SplitList(#ids, ',') AS sl
ON sl.unit = st.tableid

I've written a stored procedure to show how to do this before.
You basically have to process the string.
I tried to post the code here but the formatting got all screwy.

I have same idea with user KM. but do not need extra table Number. Just this function only.
CREATE FUNCTION [dbo].[FN_ListToTable]
(
#SplitOn char(1) --REQUIRED, the character to split the #List string on
,#List varchar(8000) --REQUIRED, the list to split apart
)
RETURNS
#ParsedList table
(
ListValue varchar(500)
)
AS
BEGIN
DECLARE #number int = 0
DECLARE #childString varchar(502) = ''
DECLARE #lengthChildString int = 0
DECLARE #processString varchar(502) = #SplitOn + #List + #SplitOn
WHILE #number < LEN(#processString)
BEGIN
SET #number = #number + 1
SET #lengthChildString = CHARINDEX(#SplitOn, #processString, #number + 1) - #number - 1
IF #lengthChildString > 0
BEGIN
SET #childString = LTRIM(RTRIM(SUBSTRING(#processString, #number + 1, #lengthChildString)))
IF #childString IS NOT NULL AND #childString != ''
BEGIN
INSERT INTO #ParsedList(ListValue) VALUES (#childString)
SET #number = #number + #lengthChildString - 1
END
END
END
RETURN
END
And here is the test:
SELECT ListValue FROM dbo.FN_ListToTable('/','a/////bb/c')
Result:
ListValue
______________________

bb
c

-- select * from dbo.Split_ID('77,106')
ALTER FUNCTION dbo.Split_ID(#String varchar(8000))
returns #temptable TABLE (ID varchar(8000))
as
begin
declare #idx int
declare #slice varchar(8000)
declare #Delimiter char(1)
set #Delimiter =','
select #idx = 1
if len(#String)<1 or #String is null return
while #idx!= 0
begin
set #idx = charindex(#Delimiter,#String)
if #idx!=0
set #slice = left(#String,#idx - 1)
else
set #slice = #String
if(len(#slice)>0)
insert into #temptable(ID) values(#slice)
set #String = right(#String,len(#String) - #idx)

You could do it like this:
create or replace
PROCEDURE UDP_SETBOOKMARK
(
P_USERID IN VARCHAR2
, P_BOOKMARK IN VARCHAR2
) AS
BEGIN
UPDATE T_ER_Bewertung
SET LESEZEICHEN = P_BOOKMARK
WHERE STAMM_ID in( select regexp_substr(P_USERID,'[^,]+', 1, level) from dual
connect by regexp_substr(P_USERID, '[^,]+', 1, level) is not null )
and ER_ID = (select max(ER_ID) from T_ER_Bewertung_Kopie);
commit;
END UDP_SETBOOKMARK;
Then try it with
Begin
UDP_SETBOOKMARK ('1,2,3,4,5', 'Test');
End;
You can use this IN-Clause with regexp_substr in other situations too, just try it.

Error 493: The column 'i' that was returned from the nodes() method cannot be
used directly. It can only be used with one of the four XML data type
methods, exist(), nodes(), query(), and value(), or in IS NULL and IS NOT
NULL checks.
The above errorr was fixed in SQL Server 2014 by using following snippet
Declare #Ids varchar(50)
Set #Ids = '1,2,3,5,4,6,7,98,234'
DECLARE #XML XML
SET #XML = CAST('<i>' + REPLACE(#Ids, ',', '</i><i>') + '</i>' AS XML)
SELECT SomeTable.*
FROM
SomeTable
cross apply #XML.nodes('i') x(i)
where SomeTable .Id = x.i.value('.', 'VARCHAR(MAX)')

Try this:
SELECT ProductId, Name, Tags
FROM Product
WHERE '1,2,3,' LIKE '%' + CAST(ProductId AS VARCHAR(20)) + ',%';
As said on the last example of this link

Tons of answers here, but to add my two cents I think STRING_SPLIT is a very simple approach to this sort of problem:
DECLARE #Ids varchar(50);
SET #Ids = '1,2,3,5,4,6,7,98,234';
SELECT *
FROM sometable
WHERE tableid IN;
(SELECT value FROM STRING_SPLIT(#Ids, ','))

Best and simple approach.
DECLARE #AccumulateKeywordCopy NVARCHAR(2000),#IDDupCopy NVARCHAR(50);
SET #AccumulateKeywordCopy ='';
SET #IDDupCopy ='';
SET #IDDup = (SELECT CONVERT(VARCHAR(MAX), <columnName>) FROM <tableName> WHERE <clause>)
SET #AccumulateKeywordCopy = ','+#AccumulateKeyword+',';
SET #IDDupCopy = ','+#IDDup +',';
SET #IDDupCheck = CHARINDEX(#IDDupCopy,#AccumulateKeywordCopy)

I ran into the same issue, and I don't want to have any footprint on the source database - i.e. no stored procedures or functions. I went about it this way:
declare #IDs table (Value int)
insert into #IDs values(1)
insert into #IDs values(2)
insert into #IDs values(3)
insert into #IDs values(5)
insert into #IDs values(4)
insert into #IDs values(6)
insert into #IDs values(7)
insert into #IDs values(98)
insert into #IDs values(234)
SELECT *
FROM sometable
WHERE tableid IN (select Value from #IDs)

The answer by #RBarryYoung (above) worked for me.
But when you have spaces in between the comma separated string values, then it will omit IDs with spaces. So I removed the spaces.
Take a look at the code snippet below.
Declare #Ids varchar(50) Set #Ids = '1 , 2,3'
set #Ids=','+Replace(#Ids,' ', '')+',';
Select * from [tblEmployee]
where Charindex(','+cast(ID as varchar(8000))+',', #Ids) > 0

WHERE someId IN (SELECT convert(int, value) FROM string_split(#stringOfCommaDelimitedIds, ','))

The simplest way i found was to use FIND_IN_SET
FIND_IN_SET(column_name, values)
values=(1,2,3)
SELECT name WHERE FIND_IN_SET(id, values)

This came in handy for one of my requirements where I did not want to use CTE and also did not want to go with the inner join.
DECLARE #Ids varchar(50);
SET #Ids = '1,2,3,5,4,6,7,98,234';
SELECT
cn1,cn2,cn3
FROM tableName
WHERE columnName in (select Value from fn_SplitString(#ids, ','))
Function for split string :
CREATE FUNCTION [dbo].[fn_SplitString] ( #stringToSplit VARCHAR(MAX), #seperator Char )
RETURNS
#returnList TABLE ([Value] [nvarchar] (500))
AS
BEGIN
DECLARE #name NVARCHAR(255)
DECLARE #pos INT
WHILE CHARINDEX(#seperator, #stringToSplit) > 0
BEGIN
SELECT #pos = CHARINDEX(#seperator, #stringToSplit)
SELECT #name = SUBSTRING(#stringToSplit, 1, #pos-1)
INSERT INTO #returnList
SELECT #name
SELECT #stringToSplit = SUBSTRING(#stringToSplit, #pos+1, LEN(#stringToSplit)-#pos)
END
INSERT INTO #returnList
SELECT #stringToSplit
RETURN
END

SQL - parametrized procedure with multiple parameters as array

I have very simple procedure:
CREATE PROCEDURE [Report]
#statusValue varchar(200) = '%'
AS
BEGIN
SELECT * FROM SomeTable
WHERE Something LIKE UPPER(#statusValue)
END
I'd like to provide user set multiple statusValue. Because there is 6 levels of statusValue in my table, I'd like to provide user to define required statusValue into procedure parameters - something like array.
I don't know, how it exactly works - I'm very new in this area - but I'm supposing to have procedure like this one:
EXEC Report #statusValue = 'statusValue1|statusValue2|statusValue3'
Do you happen to know, how can I adjust my procedure to have required output. Many thanks in advance.

Use following user defined function to return values from delimited string (say pipe):
CREATE FUNCTION [dbo].[stringlist_to_table]
(#list varchar(8000),
#delimiter nchar(1) = N',')
RETURNS #tbl TABLE (value varchar(8000)) AS
BEGIN
DECLARE #pos int,
#tmpstr varchar(8000),
#tmpval varchar(8000);
SET #tmpstr = #list;
SET #pos = charindex(#delimiter , #tmpstr);
WHILE #pos > 0
BEGIN
SET #tmpval = ltrim(rtrim(left(#tmpstr, #pos - 1)))
INSERT #tbl (value) VALUES(#tmpval)
SET #tmpstr = substring(#tmpstr, #pos + 1, len(#tmpstr))
SET #pos = charindex(#delimiter, #tmpstr)
END
INSERT #tbl(value) VALUES (ltrim(rtrim(#tmpstr)));
RETURN
END
Now use the following procedure to get the required output:
CREATE PROCEDURE [Report]
#statusValue varchar(200) = '%'
AS
BEGIN
DECLARE #iterator INT = 1;
DECLARE #total INT = 1;
DECLARE #keyword VARCHAR(100) = '';
SELECT ROW_NUMBER() OVER (ORDER BY value) SNo, value keyword
INTO #temp
FROM dbo.stringlist_to_table(#statusValue, '|')
SELECT *
INTO #output
FROM SomeTable
WHERE 1 = 0;
SELECT #total = MAX(SNo), #iterator = MIN(Sno)
FROM #temp
WHILE (#iterator <= #total)
BEGIN
SELECT #keyword = '%' + keyword + '%'
FROM #temp
WHERE SNo = #iterator;
INSERT INTO #output
SELECT *
FROM SomeTable
WHERE Something LIKE #keyword
SET #iterator = #iterator + 1;
END
SELECT *
FROM #output;
DROP TABLE #output, #temp;
END

You need the split function in this case. As there is no way to handle what you need. Another approach to add many variables. But in your case it will be enough to create split function and use it to parse your string. Please find the split function below:
CREATE FUNCTION [dbo].[ufnSplitInlineStringToParameters] (
#list NVARCHAR(MAX)
,#delim NCHAR(1) = ','
)
RETURNS TABLE
AS
RETURN
WITH csvTbl(START, STOP) AS (
SELECT START = CONVERT(BIGINT, 1)
,STOP = CHARINDEX(#delim, #list + CONVERT(NVARCHAR(MAX), #delim))
UNION ALL
SELECT START = STOP + 1
,STOP = CHARINDEX(#delim, #list + CONVERT(NVARCHAR(MAX), #delim), STOP + 1)
FROM csvTbl
WHERE STOP > 0
)
SELECT LTRIM(RTRIM(CONVERT(NVARCHAR(4000), SUBSTRING(#list, START, CASE
WHEN STOP > 0
THEN STOP - START
ELSE 0
END)))) AS VALUE
FROM csvTbl
WHERE STOP > 0
GO

One of the simplest way to achieve this is using a custom type. Sample snippet as follows:
CREATE TYPE dbo.StatusList
AS TABLE
(
statusValue varchar(200)
);
GO
CREATE PROCEDURE [Report]
#statusValue AS dbo.StatusList READONLY
AS
BEGIN
SELECT * FROM SomeTable
WHERE Something IN (SELECT * FROM #statusValue)
END
GO
--EDIT---
If you are using SSMS, you can execute the procedure as follows:
DECLARE #status dbo.StatusList
INSERT INTO #status VALUES('Pending')
EXEC [Report] #status

convert string into int SQL Server

This is the scenario:
My app will have the following:
A listbox (The checkbox property enabled) that will display a list of Something.
The user will select from the listbox (multiselect) by using the checkbox.
I will loop into All the checked items and store the ID's into an array. I will store the ID's into something like this separating the ID with a comma (1,2,3,4) and then I will use length -1 to delete the last comma.
How can I convert the string 1,2,3,4 into an integer type of data if my stored procedure is like this?
Select * from tblSomething Where ID in (1,2,3,4)

You can use the following SQL function.
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE FUNCTION [dbo].[CommaSeparatedToString]
(
#psCSString VARCHAR(8000)
)
RETURNS #otTemp TABLE(sID VARCHAR(20))
AS
BEGIN
DECLARE #sTemp VARCHAR(50)
WHILE LEN(#psCSString) > 0
BEGIN
SET #sTemp = LEFT(#psCSString, ISNULL(NULLIF(CHARINDEX(',', #psCSString) - 1, -1),
LEN(#psCSString)))
SET #psCSString = SUBSTRING(#psCSString,ISNULL(NULLIF(CHARINDEX(',', #psCSString), 0),
LEN(#psCSString)) + 1, LEN(#psCSString))
INSERT INTO #otTemp VALUES (#sTemp)
END
RETURN
END
And call in your stored procedure like
Select * from tblSomething
Where ID in (SELECT * FROM CommaSeparatedToString('1,2,3,4'))

You can use the
SELECT CAST(MyVarcharCol AS INT) FROM Table
SELECT CONVERT(INT, MyVarcharCol) FROM Table
refer this link
http://msdn.microsoft.com/en-us/library/ms187928.aspx

You need to create dynamic query for this
e.g you are getting list of values in #values paramter so prepare and run the dynamic query like this
DECLARE #query NVARCHAR(500)
DECLARE #values VARCHAR(200)
SET #values='1,2'
SET #query =N'Select * from tblSomething Where ID in ( ' + #values + ')'
SELECT #query
EXEC #Query

Use this function to split the value:
CREATE FUNCTION [dbo].[udfSplitCSV]
(
#String varchar (max),
#Delimiter varchar (10) = ','
)
RETURNS #ValueTable TABLE ([Row] int IDENTITY(1,1), [Value] varchar(max), [Length] int, [Duplicate] int NULL)
BEGIN
DECLARE #NextString varchar(max)
DECLARE #Pos int
DECLARE #NextPos int
IF #String IS NULL RETURN
--Initialize
SET #NextString = ''
SET #String = #String + #Delimiter
--Get position of first Comma
SET #Pos = charindex(#Delimiter,#String)
SET #NextPos = 1
--Loop while there is still a comma in the String
WHILE (#Pos <> 0)
BEGIN
SET #NextString = RTrim(LTrim(SubString(#String,1,#Pos - 1)))
INSERT INTO #ValueTable ([Value], [Length]) VALUES (#NextString, Len(#NextString))
SET #String = SubString(#String,#Pos+1,Len(#String))
SET #NextPos = #Pos
SET #Pos = CharIndex(#Delimiter,#String)
END
UPDATE #ValueTable
SET [Duplicate] = X.Duplicate
FROM #ValueTable VT
INNER JOIN (Select [Row], [Value], Row_Number() OVER (Partition By [Value] ORDER BY [Value], [Row]) as Duplicate FROM #ValueTable) X
ON X.[Row] = VT.[Row]
RETURN
END
-- Select * from dbo.udfSplitCSV('a , c b,c, a', ',')

When you are storing a bunch of IDs into the array, store with single quote.
so it will be ('1','2','3').
Then you no need to covert IDs into integer.

stored proc - executing a query with NOT IN where clause

i have a stored procedure
Create PROCEDURE abc
#sRemovePreviouslySelectedWhereClause nvarchar(max)
AS
BEGIN
SELECT *
FROM table
WHERE nId NOT IN (#sRemovePreviouslySelectedWhereClause)
END;
The parameter #sRemovePreviouslySelectedWhereClause can have values like 0,1 . But this fails with error message:
Conversion failed when converting the nvarchar value ' 0,1 ' to data type int.
Is there any other way to achieve this other than dynamic queries?

First, create a split function which splits your delimited string into a table:
CREATE FUNCTION [dbo].[Split]
(
#String varchar(max)
,#Delimiter char
)
RETURNS #Results table
(
Ordinal int
,StringValue varchar(max)
)
as
begin
set #String = isnull(#String,'')
set #Delimiter = isnull(#Delimiter,'')
declare
#TempString varchar(max) = #String
,#Ordinal int = 0
,#CharIndex int = 0
set #CharIndex = charindex(#Delimiter, #TempString)
while #CharIndex != 0 begin
set #Ordinal += 1
insert #Results values
(
#Ordinal
,substring(#TempString, 0, #CharIndex)
)
set #TempString = substring(#TempString, #CharIndex + 1, len(#TempString) - #CharIndex)
set #CharIndex = charindex(#Delimiter, #TempString)
end
if #TempString != '' begin
set #Ordinal += 1
insert #Results values
(
#Ordinal
,#TempString
)
end
return
end
Then change your where clause as follows:
select
t.*
from [yourTable] t
where t.[ID] not in (select cast([StringValue] as int) from dbo.Split(#sRemovePreviouslySelectedWhereClause,','))

Create FUNCTION [dbo].[fn_Split] (
#List nvarchar(2000), #SplitOn nvarchar(5)
)
RETURNS #RtnValue table (
Value nvarchar(100) )
AS
BEGIN
While (Charindex(#SplitOn,#List)>0)
Begin
Insert Into #RtnValue (value)
Select Value = ltrim(rtrim(Substring(#List,1,Charindex(#SplitOn,#List)-1)))
Set #List = Substring(#List,Charindex(#SplitOn,#List)+len(#SplitOn),len(#List))
End
Insert Into #RtnValue (Value)
Select Value = ltrim(rtrim(#List))
Return
END
**********
Create PROCEDURE abc
#sRemovePreviouslySelectedWhereClause nvarchar(max)
AS
BEGIN
SELECT *
FROM Table
WHERE nId NOT IN (select * from dbo.fn_Split(#sRemovePreviouslySelectedWhereClause,','))
END;

You have to split the #sRemovePreviouslySelectedWhereClause parameter by ',' and place the resulting values in a temp table. Then your select would look like
select * from table where nId not in (select nId from #tempIds)

This approach you're trying doesn't work. But if you're on SQL Server 2008, you could make use of the new features called Table Valued Parameters.
Basically, you create a user-defined table type
CREATE TYPE dbo.nIdTable AS TABLE(nID INT)
and you can then pass in multiple values in that TVP from the outside (e.g. from ADO.NET or such):
CREATE PROCEDURE abc(#idValues dbo.nIdTable READONLY)
and use that table variable inside your stored proc:
SELECT *
FROM table
WHERE nId NOT IN (SELECT nID FROM #idValues)

You will need to use Dynamic sql for such kind of queries.
first construct the query and
SET #sql = 'select * from table
where nId not in (' + #sRemovePreviouslySelectedWhereClause+ ')'
then use EXEC(#sql) to run the query.

Passing a varchar full of comma delimited values to a SQL Server IN function

Duplicate of
Dynamic SQL Comma Delimited Value Query
Parameterized Queries with Like and In
I have a SQL Server Stored Procedure where I would like to pass a varchar full of comma delimited values to an IN function. For example:
DECLARE #Ids varchar(50);
SET #Ids = '1,2,3,5,4,6,7,98,234';
SELECT *
FROM sometable
WHERE tableid IN (#Ids);
This does not work of course. I get the error:
Conversion failed when converting the varchar value '1,2,3,5,4,6,7,98,234' to data type int.
How can I accomplish this (or something relatively similar) without resorting to building dynamic SQL?

Of course if you're lazy like me, you could just do this:
Declare #Ids varchar(50) Set #Ids = ',1,2,3,5,4,6,7,98,234,'
Select * from sometable
where Charindex(','+cast(tableid as varchar(8000))+',', #Ids) > 0

Don't use a function that loops to split a string!, my function below will split a string very fast, with no looping!
Before you use my function, you need to set up a "helper" table, you only need to do this one time per database:
CREATE TABLE Numbers
(Number int NOT NULL,
CONSTRAINT PK_Numbers PRIMARY KEY CLUSTERED (Number ASC)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
DECLARE #x int
SET #x=0
WHILE #x<8000
BEGIN
SET #x=#x+1
INSERT INTO Numbers VALUES (#x)
END
use this function to split your string, which does not loop and is very fast:
CREATE FUNCTION [dbo].[FN_ListToTable]
(
#SplitOn char(1) --REQUIRED, the character to split the #List string on
,#List varchar(8000) --REQUIRED, the list to split apart
)
RETURNS
#ParsedList table
(
ListValue varchar(500)
)
AS
BEGIN
/**
Takes the given #List string and splits it apart based on the given #SplitOn character.
A table is returned, one row per split item, with a column name "ListValue".
This function workes for fixed or variable lenght items.
Empty and null items will not be included in the results set.
Returns a table, one row per item in the list, with a column name "ListValue"
EXAMPLE:
----------
SELECT * FROM dbo.FN_ListToTable(',','1,12,123,1234,54321,6,A,*,|||,,,,B')
returns:
ListValue
-----------
1
12
123
1234
54321
6
A
*
|||
B
(10 row(s) affected)
**/
----------------
--SINGLE QUERY-- --this will not return empty rows
----------------
INSERT INTO #ParsedList
(ListValue)
SELECT
ListValue
FROM (SELECT
LTRIM(RTRIM(SUBSTRING(List2, number+1, CHARINDEX(#SplitOn, List2, number+1)-number - 1))) AS ListValue
FROM (
SELECT #SplitOn + #List + #SplitOn AS List2
) AS dt
INNER JOIN Numbers n ON n.Number < LEN(dt.List2)
WHERE SUBSTRING(List2, number, 1) = #SplitOn
) dt2
WHERE ListValue IS NOT NULL AND ListValue!=''
RETURN
END --Function FN_ListToTable
you can use this function as a table in a join:
SELECT
Col1, COl2, Col3...
FROM YourTable
INNER JOIN FN_ListToTable(',',#YourString) s ON YourTable.ID = s.ListValue
Here is your example:
Select * from sometable where tableid in(SELECT ListValue FROM dbo.FN_ListToTable(',',#Ids) s)

No Table No Function No Loop
Building on the idea of parsing your list into a table our DBA suggested using XML.
Declare #Ids varchar(50)
Set #Ids = ‘1,2,3,5,4,6,7,98,234’
DECLARE #XML XML
SET #XML = CAST('<i>' + REPLACE(#Ids, ',', '</i><i>') + '</i>' AS XML)
SELECT *
FROM
SomeTable
INNER JOIN #XML.nodes('i') x(i)
ON SomeTable .Id = x.i.value('.', 'VARCHAR(MAX)')
These seems to have the same performance as #KM's answer but, I think, a lot simpler.

You can create a function that returns a table.
so your statement would be something like
select * from someable
join Splitfunction(#ids) as splits on sometable.id = splits.id
Here is a simular function.
CREATE FUNCTION [dbo].[FUNC_SplitOrderIDs]
(
#OrderList varchar(500)
)
RETURNS
#ParsedList table
(
OrderID int
)
AS
BEGIN
DECLARE #OrderID varchar(10), #Pos int
SET #OrderList = LTRIM(RTRIM(#OrderList))+ ','
SET #Pos = CHARINDEX(',', #OrderList, 1)
IF REPLACE(#OrderList, ',', '') <> ''
BEGIN
WHILE #Pos > 0
BEGIN
SET #OrderID = LTRIM(RTRIM(LEFT(#OrderList, #Pos - 1)))
IF #OrderID <> ''
BEGIN
INSERT INTO #ParsedList (OrderID)
VALUES (CAST(#OrderID AS int)) --Use Appropriate conversion
END
SET #OrderList = RIGHT(#OrderList, LEN(#OrderList) - #Pos)
SET #Pos = CHARINDEX(',', #OrderList, 1)
END
END
RETURN
END

It's a very common question. Canned answer, several nice techniques:
http://www.sommarskog.se/arrays-in-sql-2005.html

This works perfectly! The below answers are too complicated. Don't look at this as dynamic. Set up your store procedure as follows:
(#id as varchar(50))
as
Declare #query as nvarchar(max)
set #query ='
select * from table
where id in('+#id+')'
EXECUTE sp_executesql #query

I can suggest using WITH like this:
DECLARE #Delim char(1) = ',';
SET #Ids = #Ids + #Delim;
WITH CTE(i, ls, id) AS (
SELECT 1, CHARINDEX(#Delim, #Ids, 1), SUBSTRING(#Ids, 1, CHARINDEX(#Delim, #Ids, 1) - 1)
UNION ALL
SELECT i + 1, CHARINDEX(#Delim, #Ids, ls + 1), SUBSTRING(#Ids, ls + 1, CHARINDEX(#Delim, #Ids, ls + 1) - CHARINDEX(#Delim, #Ids, ls) - 1)
FROM CTE
WHERE CHARINDEX(#Delim, #Ids, ls + 1) > 1
)
SELECT t.*
FROM yourTable t
INNER JOIN
CTE c
ON t.id = c.id;

I think a very simple solution could be following:
DECLARE #Ids varchar(50);
SET #Ids = '1,2,3,5,4,6,7,98,234';
SELECT *
FROM sometable
WHERE ','+#Ids+',' LIKE '%,'+CONVERT(VARCHAR(50),tableid)+',%';

Without using dynamic SQL, you have to take the input variable and use a split function to put the data into a temp table and then join to that.

Thanks, for your function I Used IT........................
This is my EXAMPLE
**UPDATE [RD].[PurchaseOrderHeader]
SET [DispatchCycleNumber] ='10'
WHERE OrderNumber in(select * FROM XA.fn_SplitOrderIDs(#InvoiceNumberList))**
CREATE FUNCTION [XA].[fn_SplitOrderIDs]
(
#OrderList varchar(500)
)
RETURNS
#ParsedList table
(
OrderID int
)
AS
BEGIN
DECLARE #OrderID varchar(10), #Pos int
SET #OrderList = LTRIM(RTRIM(#OrderList))+ ','
SET #Pos = CHARINDEX(',', #OrderList, 1)
IF REPLACE(#OrderList, ',', '') <> ''
BEGIN
WHILE #Pos > 0
BEGIN
SET #OrderID = LTRIM(RTRIM(LEFT(#OrderList, #Pos - 1)))
IF #OrderID <> ''
BEGIN
INSERT INTO #ParsedList (OrderID)
VALUES (CAST(#OrderID AS int)) --Use Appropriate conversion
END
SET #OrderList = RIGHT(#OrderList, LEN(#OrderList) - #Pos)
SET #Pos = CHARINDEX(',', #OrderList, 1)
END
END
RETURN
END

If you use SQL Server 2008 or higher, use table valued parameters; for example:
CREATE PROCEDURE [dbo].[GetAccounts](#accountIds nvarchar)
AS
BEGIN
SELECT *
FROM accountsTable
WHERE accountId IN (select * from #accountIds)
END
CREATE TYPE intListTableType AS TABLE (n int NOT NULL)
DECLARE #tvp intListTableType
-- inserts each id to one row in the tvp table
INSERT #tvp(n) VALUES (16509),(16685),(46173),(42925),(46167),(5511)
EXEC GetAccounts #tvp

Its been a while but I have done this in the past using XML as a interim.
I can't take any credit for this, but I'm afraid I no longer know where I got this idea from:
-- declare the variables needed
DECLARE #xml as xml,#str as varchar(100),#delimiter as varchar(10)
-- The string you want to split
SET #str='A,B,C,D,E,Bert,Ernie,1,2,3,4,5'
-- What you want to split on. Can be a single character or a string
SET #delimiter =','
-- Convert it to an XML document
SET #xml = cast(('<X>'+replace(#str,#delimiter ,'</X><X>')+'</X>') as xml)
-- Select back from the XML
SELECT N.value('.', 'varchar(10)') as value FROM #xml.nodes('X') as T(N)

Create a table function like below which parse comma separated varchar and returns a table that can be inner joined with other tables.
CREATE FUNCTION [dbo].[fn_SplitList]
(
#inString varchar(MAX) = '',
#inDelimiter char(1) = ',' -- Keep the delimiter to 100 chars or less. Generally a delimiter will be 1-2 chars only.
)
RETURNS #tbl_Return table
(
Unit varchar(1000) COLLATE Latin1_General_BIN
)
AS
BEGIN
INSERT INTO #tbl_Return
SELECT DISTINCT
LTRIM(RTRIM(piece.value('./text()[1]', 'varchar(1000)'))) COLLATE DATABASE_DEFAULT AS Unit
FROM
(
--
-- Replace any delimiters in the string with the "X" tag.
--
SELECT
CAST(('<X>' + REPLACE(s0.prsString, s0.prsSplitDelimit, '</X><X>') + '</X>') AS xml).query('.') AS units
FROM
(
--
-- Convert the string and delimiter into XML.
--
SELECT
(SELECT #inString FOR XML PATH('')) AS prsString,
(SELECT #inDelimiter FOR XML PATH('')) AS prsSplitDelimit
) AS s0
) AS s1
CROSS APPLY units.nodes('X') x(piece)
RETURN
END
=================================================
Now consume above created table function in your code,creation of function is one time activity in your database that can be used across databases as well on same server.
DECLARE #Ids varchar(50);
SET #Ids = '1,2,3,5,4,6,7,98,234';
SELECT
*
FROM sometable AS st
INNER JOIN fn_SplitList(#ids, ',') AS sl
ON sl.unit = st.tableid

I've written a stored procedure to show how to do this before.
You basically have to process the string.
I tried to post the code here but the formatting got all screwy.

I have same idea with user KM. but do not need extra table Number. Just this function only.
CREATE FUNCTION [dbo].[FN_ListToTable]

,#List varchar(8000) --REQUIRED, the list to split apart
)

ListValue varchar(500)
)
AS
BEGIN
DECLARE #number int = 0
DECLARE #childString varchar(502) = ''
DECLARE #lengthChildString int = 0
DECLARE #processString varchar(502) = #SplitOn + #List + #SplitOn
WHILE #number < LEN(#processString)
BEGIN
SET #number = #number + 1
SET #lengthChildString = CHARINDEX(#SplitOn, #processString, #number + 1) - #number - 1
IF #lengthChildString > 0
BEGIN
SET #childString = LTRIM(RTRIM(SUBSTRING(#processString, #number + 1, #lengthChildString)))
IF #childString IS NOT NULL AND #childString != ''
BEGIN
INSERT INTO #ParsedList(ListValue) VALUES (#childString)
SET #number = #number + #lengthChildString - 1
END
END
END
RETURN
END
And here is the test:
SELECT ListValue FROM dbo.FN_ListToTable('/','a/////bb/c')
Result:

insert into #temptable(ID) values(#slice)

You could do it like this:
create or replace
PROCEDURE UDP_SETBOOKMARK
(
P_USERID IN VARCHAR2
, P_BOOKMARK IN VARCHAR2
) AS
BEGIN
UPDATE T_ER_Bewertung
SET LESEZEICHEN = P_BOOKMARK
WHERE STAMM_ID in( select regexp_substr(P_USERID,'[^,]+', 1, level) from dual
connect by regexp_substr(P_USERID, '[^,]+', 1, level) is not null )
and ER_ID = (select max(ER_ID) from T_ER_Bewertung_Kopie);
commit;
END UDP_SETBOOKMARK;
Then try it with
Begin
UDP_SETBOOKMARK ('1,2,3,4,5', 'Test');
End;
You can use this IN-Clause with regexp_substr in other situations too, just try it.

Error 493: The column 'i' that was returned from the nodes() method cannot be
used directly. It can only be used with one of the four XML data type
methods, exist(), nodes(), query(), and value(), or in IS NULL and IS NOT
NULL checks.
The above errorr was fixed in SQL Server 2014 by using following snippet
Declare #Ids varchar(50)
Set #Ids = '1,2,3,5,4,6,7,98,234'
DECLARE #XML XML
SET #XML = CAST('<i>' + REPLACE(#Ids, ',', '</i><i>') + '</i>' AS XML)
SELECT SomeTable.*
FROM
SomeTable
cross apply #XML.nodes('i') x(i)
where SomeTable .Id = x.i.value('.', 'VARCHAR(MAX)')

Try this:
SELECT ProductId, Name, Tags
FROM Product
WHERE '1,2,3,' LIKE '%' + CAST(ProductId AS VARCHAR(20)) + ',%';
As said on the last example of this link

Tons of answers here, but to add my two cents I think STRING_SPLIT is a very simple approach to this sort of problem:
DECLARE #Ids varchar(50);
SET #Ids = '1,2,3,5,4,6,7,98,234';
SELECT *
FROM sometable
WHERE tableid IN;
(SELECT value FROM STRING_SPLIT(#Ids, ','))

Best and simple approach.

I ran into the same issue, and I don't want to have any footprint on the source database - i.e. no stored procedures or functions. I went about it this way:
declare #IDs table (Value int)
insert into #IDs values(1)
insert into #IDs values(2)
insert into #IDs values(3)
insert into #IDs values(5)
insert into #IDs values(4)
insert into #IDs values(6)
insert into #IDs values(7)
insert into #IDs values(98)
insert into #IDs values(234)
SELECT *
FROM sometable
WHERE tableid IN (select Value from #IDs)

The answer by #RBarryYoung (above) worked for me.
But when you have spaces in between the comma separated string values, then it will omit IDs with spaces. So I removed the spaces.
Take a look at the code snippet below.
Declare #Ids varchar(50) Set #Ids = '1 , 2,3'
set #Ids=','+Replace(#Ids,' ', '')+',';
Select * from [tblEmployee]
where Charindex(','+cast(ID as varchar(8000))+',', #Ids) > 0

WHERE someId IN (SELECT convert(int, value) FROM string_split(#stringOfCommaDelimitedIds, ','))

The simplest way i found was to use FIND_IN_SET
FIND_IN_SET(column_name, values)
values=(1,2,3)
SELECT name WHERE FIND_IN_SET(id, values)

This came in handy for one of my requirements where I did not want to use CTE and also did not want to go with the inner join.
DECLARE #Ids varchar(50);
SET #Ids = '1,2,3,5,4,6,7,98,234';
SELECT
cn1,cn2,cn3
FROM tableName
WHERE columnName in (select Value from fn_SplitString(#ids, ','))
Function for split string :
CREATE FUNCTION [dbo].[fn_SplitString] ( #stringToSplit VARCHAR(MAX), #seperator Char )
RETURNS
#returnList TABLE ([Value] [nvarchar] (500))
AS
BEGIN
DECLARE #name NVARCHAR(255)
DECLARE #pos INT
WHILE CHARINDEX(#seperator, #stringToSplit) > 0
BEGIN
SELECT #pos = CHARINDEX(#seperator, #stringToSplit)
SELECT #name = SUBSTRING(#stringToSplit, 1, #pos-1)
INSERT INTO #returnList
SELECT #name
SELECT #stringToSplit = SUBSTRING(#stringToSplit, #pos+1, LEN(#stringToSplit)-#pos)
END
INSERT INTO #returnList
SELECT #stringToSplit
RETURN
END
