I have 4 stored procedures.
The following is used to be invoked by C#:
ALTER PROCEDURE [dbo].[sp_retrieveResourceShell]
AS
BEGIN
SET NOCOUNT ON
DECLARE #result NVARCHAR(MAX)
EXEC [dbo].[sp_retrieveResTree]
#pid = NULL,
#ret = #result OUTPUT
***select*** #result
END
These are internal stored procedures:
ALTER PROCEDURE [dbo].[sp_retrieveResTree]
(#pid UNIQUEIDENTIFIER,
#ret NVARCHAR(MAX) OUTPUT)
AS
BEGIN
DECLARE #mdlId UNIQUEIDENTIFIER,
#mdlGroup NVARCHAR(MAX)
DECLARE mdlCursor CURSOR FOR
......
DECLARE #subRet NVARCHAR(MAX),
#viewRet NVARCHAR(MAX)
EXEC [dbo].[sp_retrieveResTree]
#pid = #mdlId,
#ret = #subRet OUTPUT
EXEC dbo.sp_retrieveResView
#mdlId = #mdlId,
#ret = #viewRet OUTPUT
SET #mdlGroup = #mdlGroup + FORMATMESSAGE('{"Id":"%s","Name":"%s","Subs":%s,"Views":%s},'...)
.......
SET #ret = FORMATMESSAGE('[%s]',#mdlGroup)
END
ALTER PROCEDURE [dbo].[sp_retrieveResView]
(#mdlId UNIQUEIDENTIFIER,
#ret NVARCHAR(MAX) OUTPUT)
AS
BEGIN
SET #ret = FORMATMESSAGE('[%s]',#viewGroup)
END
When I invoke sp_retrieveResourceShell like this:
DECLARE #return_value int
EXEC #return_value = [dbo].[sp_retrieveResourceShell]
SELECT 'Return Value' = #return_value
I can get a truncated string with ellipsis at the string tail.
how to get the full string without ellipsis?
update
Changed formatmessage function to string concatenation likes
SET #mdlGroup = #mdlGroup + '{"Id":"' + CAST(#mdlId AS CHAR(36))+ '","Name":"' + #mdlName + '","Subs":' + #subRet + ',"Views":' + #viewRet +'},'
when using string concatenation , likes
SET #ret = N'[' + #mdlGroup + N']'
and refernce to [n]varchar(max) + [n]varchar(max)
i got the right full string . Thanks to #MartinSmith at the same time .
I created a stored procedure that looks like this.
CREATE PROCEDURE [EXP_RfPickAfter] (
#SESSIONVALUE xml,
#WorkDSArray nvarchar(max),
#UserSignonDS nvarchar(max),
#Direction nvarchar(max),
#ImmediateCount nvarchar(max),
#CCWorkUnit nvarchar(max),
#PartialPick nvarchar(max),
#RETURNVALUE nvarchar(max) output
)
AS
SET NOCOUNT ON;
#workDSArray has this long string in it

I am trying to parse containerID and its value from this string and use it in a select statement in my stored procedure, but I am unsure how to parse only the containerID.
Any help would be appreciated
This is what I did to get the right ID I had to trigger off of something else. This is not ideal because I don't know if the string will change. If anybody knows a better way please post and thank you #ymuribbi you helped me out a ton. I edited this to show my full solution just in case someone else runs into this issue.

As #hogan stated in his comment, you can use string operators for extraction with some while and if-else statements
-- I am editing my answer.
To retrieve the container ID you use a store procedure like this:
create proc getid (#string varchar(max)) as
declare #containerIdIndex int = (select charindex('CONTAINER_ID',#string))
declare #internalContainerIndex int = (select(Charindex('INTERNAL_CONTAINER', #string)))
declare #range int = #internalContainerindex-#containerIdindex+12
declare #start int = #containerIdIndex+12 --12 is to pass the 'Container_ID'
declare #containerId varchar(max)
set #containerId = substring(#string,#start,#range)
print #containerId
I have a nvarchar(MAX) in my stored procedure which contains the list of int values, I did it like this as it is not possible to pass int list to my stored procedure,
but, now I am getting problem as my datatype is int and I want to compare the list of string.
Is there a way around by which I can do the same?
---myquerry----where status in (#statuslist)
but the statuslist contains now string values not int, so how to convert them into INT?
UPDate:
USE [Database]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[SP]
(
#FromDate datetime = 0,
#ToDate datetime = 0,
#ID int=0,
#List nvarchar(MAX) //This is the List which has string ids//
)
AS
SET FMTONLY OFF;
DECLARE #sql nvarchar(MAX),
#paramlist nvarchar(MAX)
SET #sql = 'SELECT ------ and Code in(#xList)
and -------------'
SELECT #paramlist = '#xFromDate datetime,#xToDate datetime,#xId int,#xList nvarchar(MAX)'
EXEC sp_executesql #sql, #paramlist,
#xFromDate = #FromDate ,#xToDate=#ToDate,#xId=#ID,#xList=#List
PRINT #sql
So when I implement that function that splits then I am not able to specify the charcter or delimiter as it is not accepting it as (#List,',').
or (','+#List+',').
It is possible to send an int list to your stored procedure using XML parameters. This way you don't have to tackle this problem anymore and it is a better and more clean solution.
have a look at this question:
Passing an array of parameters to a stored procedure
or check this code project:
http://www.codeproject.com/Articles/20847/Passing-Arrays-in-SQL-Parameters-using-XML-Data-Ty
However if you insist on doing it your way you could use this function:
CREATE FUNCTION [dbo].[fnStringList2Table]
(
#List varchar(MAX)
)
RETURNS
#ParsedList table
(
item int
)
AS
BEGIN
DECLARE #item varchar(800), #Pos int
SET #List = LTRIM(RTRIM(#List))+ ','
SET #Pos = CHARINDEX(',', #List, 1)
WHILE #Pos > 0
BEGIN
SET #item = LTRIM(RTRIM(LEFT(#List, #Pos - 1)))
IF #item <> ''
BEGIN
INSERT INTO #ParsedList (item)
VALUES (CAST(#item AS int))
END
SET #List = RIGHT(#List, LEN(#List) - #Pos)
SET #Pos = CHARINDEX(',', #List, 1)
END
RETURN
END
Call it like this:
SELECT *
FROM Table
WHERE status IN (SELECT * from fnStringList2Table(#statuslist))
You can work with string list too. I always do.
declare #statuslist nvarchar(max)
set #statuslist = '1, 2, 3, 4'
declare #sql nvarchar(max)
set #sql = 'select * from table where Status in (' + #statuslist + ')'
Execute(#sql)
You can do this by using sql function which will return you an integer array..
It would be great if you pass #Delimiter separated string to your stored procedure which could be processed properly afterwards.
Write one function to split the data as following
CREATE FUNCTION [dbo].[SplitValues] (#StringArray NVARCHAR(MAX), #Delimiter NVARCHAR(10))
RETURNS #ResultedValues table
(
ResultValue INT
)
AS
BEGIN
DECLARE #Tokens TABLE(Token nvarchar)
DECLARE #String nvarchar
WHILE (CHARINDEX(#Delimiter,#StringArray)>0)
BEGIN
INSERT INTO #Tokens (Token) VALUES (LTRIM(RTRIM(SUBSTRING(#StringArray,1,CHARINDEX(#Delimiter,#StringArray)-1))))
SET #String = SUBSTRING(#StringArray,
CHARINDEX(#Delimiter,#StringArray)+LEN(#Delimiter),LEN(#StringArray))
END
INSERT INTO #ResultedValues (ResultValue ) VALUES ( CAST(LTRIM(RTRIM(#String)) AS INT))
RETURN
END
And then use it like following, i am using (,) as #Delimiter here
SELECT ResultValue [YourSchema].[SplitValues](#statuslist,',')
Actually, you can send the list of int values to your procedure by creating a User Defined Table Type. However, this implies more work in order to populate the table parameter.
In your case, you can use the sp_executesql stored procedure to achieve what you want like this:
declare #statement nvarchar(4000) = '----your query---- where status in ('
+ #statusList +')'
sp_executesql #statement
here is an example of how to do it and the Link for more informations
ALTER FUNCTION iter_intlist_to_tbl (#list nvarchar(MAX))
RETURNS #tbl TABLE (listpos int IDENTITY(1, 1) NOT NULL,
number int NOT NULL) AS
BEGIN
DECLARE #startpos int,
#endpos int,
#textpos int,
#chunklen smallint,
#str nvarchar(4000),
#tmpstr nvarchar(4000),
#leftover nvarchar(4000)
SET #textpos = 1
SET #leftover = ''
WHILE #textpos <= datalength(#list) / 2
BEGIN
SET #chunklen = 4000 - datalength(#leftover) / 2
SET #tmpstr = ltrim(#leftover + substring(#list, #textpos, #chunklen))
SET #textpos = #textpos + #chunklen
SET #startpos = 0
SET #endpos = charindex(' ' COLLATE Slovenian_BIN2, #tmpstr)
WHILE #endpos > 0
BEGIN
SET #str = substring(#tmpstr, #startpos + 1, #endpos - #startpos - 1)
IF #str <> ''
INSERT #tbl (number) VALUES(convert(int, #str))
SET #startpos = #endpos
SET #endpos = charindex(' ' COLLATE Slovenian_BIN2, #tmpstr, #startpos + 1)
END
SET #leftover = right(#tmpstr, datalength(#tmpstr) / 2 - #startpos)
END
IF ltrim(rtrim(#leftover)) <> ''
INSERT #tbl (number) VALUES(convert(int, #leftover))
RETURN
END

I have several occurrences of differences strings in the columns, like this example
'dsasdasdsd'+'ewewewew'+'45454545'+(avg('uuuuuuu'))
I need to split this string into several columns with the substrings that are between
aphostropes
like this:
Column 1 = dsasdasdsd
Column 2 = ewewewew
Column 3 = 45454545
Column 4 = uuuuuuu
The numbers of apperances are random, thefore the length of the original column is also not fixed (from 50 char to > 1000)
DECLARE #InStr VarChar(1000) = '''dsasdasdsd''+''ewewewew''+''45454545''+(avg(''uuuuuuu''))'''
DECLARE #intStart INT = 0
DECLARE #intEnd INT = 1
DECLARE #ColNo INT = 1
DECLARE #MyString VARCHAR(2000)
DECLARE #SelectString VARCHAR(8000) = 'SELECT '
WHILE(#intStart < LEN(#InStr) )
BEGIN

END

I have been playing with this and this does run but unfortunately I don't have time right now to carry on with it but maybe you can improve on this?

You will be able to achieve this using CHARINDEX() and SUBSTRING()
Following example shows for splitting to 2 columns. When it has more columns, query will be get little more complicated. However, you can follow this to build your query.
SELECT OriginalColumn
, SUBSTRING(OriginalColumn, 1,CHARINDEX('x',OriginalColumn,1)-1) AS Column1
, SUBSTRING(OriginalColumn, CHARINDEX('x',OriginalColumn,1) + 1 ,CHARINDEX('x',OriginalColumn,CHARINDEX('x',OriginalColumn,1)-1)) AS Column2
FROM YourTable
I have used "x" as the delimiter in the example. Following is a sample result
try this:
declare #delim char
set #delim = ''''
declare #str nvarchar(max)
declare #substr nvarchar(max)
declare #newstr nvarchar(max)
declare #tmpTable table (partStrings nvarchar(max))
declare #count int
set #count = 0
select #str = <***Your String***>
while(charindex(#delim,#str) != 0)
begin
set #count = #count + 1
Select #substr = substring(#str,1,charindex(#delim,#str)-1)
if((#count % 2) = 0)
begin

I need to pull a specific substring from a string of the form:
foo=abc;bar=def;baz=ghi
For example, how would I get the value of "bar" from that string?
You can use charindex and substring. For example, to search for the value of "baz":
declare #str varchar(128)
set #str = 'foo=abc;bar=def;baz=ghi'
-- Make sure #str starts and ends with a ;
set #str = ';' + #str + ';'
select substring(#str,
charindex(';baz=',#str) + len(';baz='),
charindex('=',#str,charindex(';baz=',#str)) - charindex(';baz=',#str) - 1)
Or for the value of "foo" at the start of the string:
select substring(#str,
charindex(';foo=',#str) + len(';foo='),
charindex('=',#str,charindex(';foo=',#str)) - charindex(';foo=',#str) - 1)
Here's a UDF to accomplish this (more readable version inspired by BlackTigerX's answer):
create function dbo.FindValueInString(
#search varchar(256),
#name varchar(30))
returns varchar(30)
as
begin
declare #name_start int
declare #name_length int
declare #value_start int
declare #value_end int
set #search = ';' + #search
set #name_start = charindex(';' + #name + '=',#search)
if #name_start = 0
return NULL
set #name_length = len(';' + #name + '=')
set #value_start = #name_start + #name_length
set #value_end = charindex(';', #search, #value_start)
return substring(#search, #value_start, #value_end - #value_start)
end
As you can see, this isn't easy in Sql Server :) Better do this in the client language, or normalize your database so the substrings go in their own columns.
I have a generalized solution that works for this problem:
CREATE FUNCTION [dbo].[fn_StringBetween]
(
#BaseString varchar(max),
#StringDelim1 varchar(max),
#StringDelim2 varchar(max)
)
RETURNS varchar(max)
AS
BEGIN
DECLARE #at1 int
DECLARE #at2 int
DECLARE #rtrn varchar(max)
SET #at1 = CHARINDEX(#StringDelim1, #BaseString)
IF #at1 > 0
BEGIN
SET #rtrn = SUBSTRING(#BaseString, #at1
+ LEN(#StringDelim1), LEN(#BaseString) - #at1)
SET #at2 = CHARINDEX(#StringDelim2, #rtrn)
IF #at2 > 0
SET #rtrn = LEFT(#rtrn, #at2 - 1)
END
RETURN #rtrn
END
so if you run (just wrap your original string to be searched with ';' at beginning and end):
PRINT dbo.fn_StringBetween(';foo=abc;bar=def;baz=ghi;', ';bar=', ';')
you will get 'def' returned.
look into the PATINDEX function. It has wildcard matching which should help you..
you can use this function
alter function FindValue(#txt varchar(200), #find varchar(200))
returns varchar(200)
as
begin
declare
#firstPos int,
#lastPos int
select #firstPos = charindex(#find, #txt), #lastPos = charindex(';', #txt, #firstPos+5)
select #lastPos = len(#txt)+1 where #lastPos = 0
return substring(#txt, #firstPos+len(#find)+1, #lastPos-#firstPos-len(#find)-1)
end
select dbo.FindValue('foo=abc;bar=def;baz=ghi', 'bar')
update: was not using the length of #find
this is assuming that the string will have the same string format just substitute the column name for the 'foo=abc;bar=def;baz=ghi'
select substring('foo=abc;bar=def;baz=ghi',patindex('%bar=%','foo=abc;bar=def;baz=ghi')+4, len('foo=abc;bar=def;baz=ghi')-patindex('%;baz=%','foo=abc;bar=def;baz=ghi')-4)
This can achieve in simple way
DECLARE #str VARCHAR(30)
DECLARE #start INT
SET #str='foo=abc;bar=def;baz=ghi'
SET #start=CHARINDEX('bar',#str)
PRINT SUBSTRING(#str,#start,3)
