I have this function, but I wanted to pass a table so as to use the same function to get the job done for multiple tables. For example, I want this function work for table1, and table2. But it is just for table1 currently. I was trying to use a dynamic sql in vain; it doesn't pass the parameter selected.
Can someone help? Give me guide on how to pass table as a parameter.
Sample data, table1
CREATE TABLE table1 (id int identity (1,1), name varchar(60))
INSERT INTO table1
VALUES ('a1, a2, a9, a8')
Sample data, table2
CREATE TABLE table2 (id int identity (1,1), name varchar(60))
INSERT INTO table2
VALUES ('a1, a2, a9, a8')
The function:
CREATE FUNCTION f_split
(#id INT)
RETURNS #ab
TABLE (name VARCHAR(20),
ab1 VARCHAR(5)
)
AS
BEGIN
DECLARE #temp TABLE (rn INT, name VARCHAR(5))
INSERT INTO #temp(rn, name)
SELECT ROW_NUMBER() OVER(ORDER BY LTRIM(RTRIM(Split.a.value('.', 'NVARCHAR(MAX)'))) ASC) rn, LTRIM(RTRIM(Split.a.value('.', 'NVARCHAR(MAX)'))) Result
FROM
(
SELECT CAST('<X>'+REPLACE([name], ',', '</X><X>')+'</X>' AS XML) AS String
FROM table1 where id = #id
) AS A
CROSS APPLY String.nodes('/X') AS Split(a)
ORDER BY 1
INSERT INTO #ab
SELECT * FROM #temp
RETURN
END
This gives the result from table1.
SELECT * FROM F_SPLIT(1)
But I want the same function to work for table2 as well.
Any help is appreciated.
Use a partitioned view, which will allow you to specify the table name as a parameter in the where clause.
Start by creating a view that unions the two tables, plus an additional column to indicate which table the row comes from.
CREATE VIEW BothTables AS
SELECT 'Table1' TableName, * FROM Table1
UNION ALL
SELECT 'Table2' TableName, * FROM Table2
Then modify your function. When you pass the table name, use it to select a subset of rows from the view. So instead of
SELECT CAST('<X>'+REPLACE([name], ',', '</X><X>')+'</X>' AS XML) AS String
FROM table1
WHERE id = #id
Use
SELECT CAST('<X>'+REPLACE([name], ',', '</X><X>')+'</X>' AS XML) AS String
FROM BothTables
WHERE TableName = #TableName
AND id = #id

I am trying to insert data to a table from another where data is not already exists
The table I am inserting the data into
CREATE TABLE #T(Name VARCHAR(10),Unit INT, Id INT)
INSERT INTO #T
VALUES('AAA',10,100),('AAB',11,102),('AAC',12,130)
The table I am selecting the data from
CREATE TABLE #T1(Name VARCHAR(10),TypeId INT,Unit INT, Id INT)
INSERT INTO #T1
VALUES('AAA',3,10,100),('AAA',3,10,106)
In this case I want to select ('AAA',3,10,106) from #T1 because AAA,106 combination not exists in #T
Basically what I want is to populate unique Name and Id combination
I tried below which doesn't seems to work
SELECT *
FROM #T1
WHERE NOT EXISTS(SELECT * FROM #T)
You have to somehow correlate the two tables:
SELECT *
FROM #T1
WHERE NOT EXISTS(SELECT *
FROM #T
WHERE #T1.Name = #T.Name AND #T1.ID = #T.ID)
The above query essentially says: get me those records of table #T1 which do not have a related record in #T having the same Name and ID values.
Your best bet is probably to use a insert statement with a subquery. Something like this:
SQL Insert Into w/Subquery - Checking If Not Exists
Edit: If you're still stuck, try this--
INSERT INTO #T (Name, Unit, Id)
SELECT Name, Unit, Id
FROM #T1
WHERE
NOT EXISTS (SELECT Name, Unit, Id FROM #T
WHERE #T.Name = #T1.Name AND #T.Unit = #T1.Unit AND #T.Id = #T1.Id)
I've tried flexing my Google-fu to no avail so here I am! Unfortunately I cannot change anything about these tables as they are coming out of an application that I have to report out of.
In SQL Server 2008, I'm trying to replace multiple values in one text string column (Table 1) with the value from another table (Table 2).
Thanks in advance!!
Table 1
id value
-------------
1 a1, a2, a3
2 a2, a3
3 a4
Table 2
id value
---------
a1 Value1
a2 Value2
a3 Value3
a4 Value4
Desired Output
id value
-----------------------------
1 Value1, Value2, Value3
2 Value2, Value3
3 Value4
I'm sorry for this solution in advance :) It does what you need though:
create table TableA(
id int,
string varchar(255)
)
create table table2(
id varchar , text varchar(255)
)
insert into tableA values(1,'a,b,c,d')
insert into tableA values(2,'e,f')
insert into table2 values('a', 'value1')
insert into table2 values('b', 'value2')
insert into table2 values('c', 'value3')
insert into table2 values('d', 'value4')
insert into table2 values('e', 'value5')
insert into table2 values('f', 'value6')
select id, left(myConcat,len(myConcat)-1) from (
select c.id, replace(replace(CAST(CAST('<i'+stuff((select * from(
SELECT A.[id] ,
Split.a.value('.', 'VARCHAR(1000)') AS String
FROM (SELECT [id],
CAST ('<M>' + REPLACE([string], ',', '</M><M>') + '</M>' AS XML) AS String
FROM TableA) AS A CROSS APPLY String.nodes ('/M') AS Split(a)) a
inner join table2 b on a.String = b.id
where a.id = c.id
FOR XML PATH ('')
),1,2,'') AS XML).query('/text') AS VARCHAR(1000)),'<text>',''),'</text>',',') myConcat
from TableA c
group by c.id
) d
Using the DelimitedSplit8K found at http://www.sqlservercentral.com/articles/Tally+Table/72993/ as suggested by #user1221684 you might come up with something like this. Working with delimited data like this is a pain. First you have to parse the string so you can join it to the other table and then ruin by stuffing it back into a denormalized form.
Make sure that if you use this that you understand that function and what this code is doing. This is not entry level t-sql and it will be YOU supporting this at 3am when it breaks in production, not me.

This site has a delimited text split function http://www.sqlservercentral.com/articles/Tally+Table/72993/
Use that function to split your values out into a temp table. Replace the values in your temp table with the new values. Then use STUFF..FOR XML to combine the records back together and update your table.
One query with a few cte's should be able to handle all of this after you add the function to your database.
Example using Sql Fiddle
Use this:
DECLARE #t TABLE(id int,value varchar(255))
INSERT INTO #t (id,value)
VALUES(1,'a1'),(2,'a2'),(3,'a3')....
SELECT *,STUFF((SELECT DISTINCT ','+value FROM #t WHERE id=t.id)
FOR XML PATH('')),1,2,' ')
FROM (SELECT DISTINCT ID FROM #t) t
DISTINCT in the case of same id, otherwise let it go
I have like 10 diff temporary tables created in SQL server, what I am looking to do is union them all to a final temporary table holding them all on one table. All the tables have only one row and look pretty much exactly like the two temp tables below.
Here is what I have so far this is an example of just two of the temp tables as their all exactly like this one then #final is the table I want to union the all to:
create table #lo
(
mnbr bigint
)
insert into #login (mnbr)
select distinct (_ID)
FROM [KDB].[am_LOGS].[dbo].[_LOG]
WHERE time >= '2012-7-26 9:00:00
Select count(*) as countreject
from #lo
create table #pffblo
(
mber_br
)
insert into #pffblo (mber_br)
select distinct (mber_br)
from individ ip with (nolock)
join memb mp with (nolock)
on( ip.i_id=mp.i_id and mp.p_type=101)
where ip.times >= '2012-9-26 11:00:00.000'
select count(*) as countaccept
create table #final
(
countreject bigint
, Countacceptbigint
.....
)
insert into #final (Countreject, Countaccept....more rows here...)
select Countreject, Countaccept, ...more rows selected from temp tables.
from #final
union
(select * from #lo)
union
(select * from #pffblo)
select *
from #final
drop table #lo
drop table #pffblo
drop table #final
if this the form to union the rows form those temp tables to this final one. Then is this correct way to show all those rows that were thus unioned. When I do this union I get message number of columns in union need to match number of columns selected in union
I think you're using a union the wrong way. A union is used when you have to datasets that are the same structure and you want to put them into one dataset.
e.g.:
CREATE TABLE #Table1
(
col1 BIGINT
)
CREATE TABLE #Table2
(
col1 BIGINT
)
--populate the temporary tables
CREATE TABLE #Final
(
col1 BIGINT
)
INSERT INTO #Final (col1)
SELECT *
FROM #Table1
UNION
SELECT *
FROM #Table2
drop table #table1
drop table #table2
drop table #Final
I think what you're trying to do is get 1 data set with the count of all your tables in it. Union won't do this.
The easiest way (although not very performant) would be to do select statements like the following:
CREATE TABLE #Table1
(
col1 BIGINT
)
CREATE TABLE #Table2
(
col1 BIGINT
)
--populate the temporary tables
CREATE TABLE #Final
(
col1 BIGINT,
col2 BIGINT
)
INSERT INTO #Final (col1, col2)
select (SELECT Count(*) FROM #Table1) as a, (SELECT Count(*) FROM #Table2) as b
select * From #Final
drop table #table1
drop table #table2
drop table #Final
It appears that you want to take the values from each of temp tables and then place then into a single row of data. This is basically a PIVOT, you can use something like this:
create table #final
(
countreject bigint
, Countaccept bigint
.....
)
insert into #final (Countreject, Countaccept....more rows here...)
select
from
(
select count(*) value, 'Countreject' col -- your UNION ALL's here
from #lo
union all
select count(*) value, 'countaccept' col
from #pffblo
) x
pivot
(
max(value)
for col in ([Countreject], [countaccept])
) p
Explanation:
You will create a subquery similar to this that will contain the COUNT for each of your individual temp table. There are two columns in the subquery, one column contains the count(*) from the table and the other column is the name of the alias:
select count(*) value, 'Countreject' col
from #lo
union all
select count(*) value, 'countaccept' col
from #pffblo
You then PIVOT these values to insert into your final temp table.
If you do not want to use PIVOT, then you can use a CASE statement with an aggregate function:
insert into #final (Countreject, Countaccept....more rows here...)
select max(case when col = 'Countreject' then value end) Countreject,
max(case when col = 'countaccept' then value end) countaccept
from
(
select count(*) value, 'Countreject' col -- your UNION ALL's here
from #lo
union all
select count(*) value, 'countaccept' col
from #pffblo
) x
Or you might be able to JOIN all of the temp tables similar to this, where you create a row_number() for the one record in the table and then you join the tables with the row_number():
insert into #final (Countreject, Countaccept....more rows here...)
select isnull(lo.Countreject, 0) Countreject,
isnull(pffblo.Countaccept, 0) Countaccept
from
(
select count(*) Countreject,
row_number() over(order by (SELECT 0)) rn
from #lo
) lo
left join
(
select count(*) Countaccept,
row_number() over(order by (SELECT 0)) rn
from #pffblo
) pffblo
on lo.rn = pffblo.rn
SELECT *
INTO #1
FROM TABLE2
UNION
SELECT *
FROM TABLE3
UNION
SELECT *
FROM TABLE4
If you would like to get count for each temporary table in the resulting table, you will need just to calculate it for each column in subquery:
INSERT INTO result (col1, col2,...
SELECT
(SELECT COUNT() FROM tbl1) col1
,(SELECT COUNT() FROM tbl2) col2
..
After having created a temporary table and declaring the data types like so;
CREATE TABLE #TempTable(
ID int,
Date datetime,
Name char(20))
How do I then insert the relevant data which is already held on a physical table within the database?
INSERT INTO #TempTable (ID, Date, Name)
SELECT id, date, name
FROM physical_table
To insert all data from all columns, just use this:
SELECT * INTO #TempTable
FROM OriginalTable
Don't forget to DROP the temporary table after you have finished with it and before you try creating it again:
DROP TABLE #TempTable
SELECT ID , Date , Name into #temp from [TableName]
My way of Insert in SQL Server. Also I usually check if a temporary table exists.
IF OBJECT_ID('tempdb..#MyTable') IS NOT NULL DROP Table #MyTable
SELECT b.Val as 'bVals'
INTO #MyTable
FROM OtherTable as b
SELECT *
INTO #TempTable
FROM table
I have provided two approaches to solve the same issue,
Solution 1: This approach includes 2 steps, first create a temporary table with
specified data type, next insert the value from the existing data
table.
CREATE TABLE #TempStudent(tempID int, tempName varchar(MAX) )
INSERT INTO #TempStudent(tempID, tempName) SELECT id, studName FROM students where id =1
SELECT * FROM #TempStudent
Solution 2: This approach is simple, where you can directly insert the values to
temporary table, where automatically the system take care of creating
the temp table with the same data type of original table.
SELECT id, studName INTO #TempStudent FROM students where id =1
SELECT * FROM #TempStudent
After you create the temp table you would just do a normal INSERT INTO () SELECT FROM
INSERT INTO #TempTable (id, Date, Name)
SELECT t.id, t.Date, t.Name
FROM yourTable t
The right query:
drop table #tmp_table
select new_acc_no, count(new_acc_no) as count1
into #tmp_table
from table
where unit_id = '0007'
group by unit_id, new_acc_no
having count(new_acc_no) > 1
insert into #temptable (col1, col2, col3)
select col1, col2, col3 from othertable
Note that this is considered poor practice:
insert into #temptable
select col1, col2, col3 from othertable
If the definition of the temp table were to change, the code could fail at runtime.
Basic operation of Temporary table is given below, modify and use as per your requirements,
-- CREATE A TEMP TABLE
CREATE TABLE #MyTempEmployeeTable(tempUserID varchar(MAX), tempUserName varchar(MAX) )
-- INSERT VALUE INTO A TEMP TABLE
INSERT INTO #MyTempEmployeeTable(tempUserID,tempUserName) SELECT userid,username FROM users where userid =21
-- QUERY A TEMP TABLE [This will work only in same session/Instance, not in other user session instance]
SELECT * FROM #MyTempEmployeeTable
-- DELETE VALUE IN TEMP TABLE
DELETE FROM #MyTempEmployeeTable
-- DROP A TEMP TABLE
DROP TABLE #MyTempEmployeeTable
INSERT INTO #TempTable(ID, Date, Name)
SELECT OtherID, OtherDate, OtherName FROM PhysicalTable
insert #temptable
select idfield, datefield, namefield from yourrealtable
All the above mentioned answers will almost fullfill the purpose. However, You need to drop the temp table after all the operation on it. You can follow-
INSERT INTO #TempTable (ID, Date, Name)
SELECT id, date, name
FROM physical_table;
IF OBJECT_ID('tempdb.dbo.#TempTable') IS NOT NULL
DROP TABLE #TempTable;
I am trying to select some fields from one table and insert them into an existing table from a stored procedure. Here is what I am trying:
SELECT col1, col2
INTO dbo.TableTwo
FROM dbo.TableOne
WHERE col3 LIKE #search_key
I think SELECT ... INTO ... is for temporary tables which is why I get an error that dbo.TableTwo already exists.
How can I insert multiple rows from dbo.TableOne into dbo.TableTwo?
SELECT ... INTO ... only works if the table specified in the INTO clause does not exist - otherwise, you have to use:
INSERT INTO dbo.TABLETWO
SELECT col1, col2
FROM dbo.TABLEONE
WHERE col3 LIKE #search_key
This assumes there's only two columns in dbo.TABLETWO - you need to specify the columns otherwise:
INSERT INTO dbo.TABLETWO
(col1, col2)
SELECT col1, col2
FROM dbo.TABLEONE
WHERE col3 LIKE #search_key
There are two different ways to implement inserting data from one table to another table.
For Existing Table - INSERT INTO SELECT
This method is used when the table is already created in the database earlier and the data is to be inserted into this table from another table. If columns listed in insert clause and select clause are same, they are not required to list them. It is good practice to always list them for readability and scalability purpose.
----Create testable
CREATE TABLE TestTable (FirstName VARCHAR(100), LastName VARCHAR(100))
----INSERT INTO TestTable using SELECT
INSERT INTO TestTable (FirstName, LastName)
SELECT FirstName, LastName
FROM Person.Contact
WHERE EmailPromotion = 2
----Verify that Data in TestTable
SELECT FirstName, LastName
FROM TestTable
----Clean Up Database
DROP TABLE TestTable
For Non-Existing Table - SELECT INTO
This method is used when the table is not created earlier and needs to be created when data from one table is to be inserted into the newly created table from another table. The new table is created with the same data types as selected columns.
----Create a new table and insert into table using SELECT INSERT
SELECT FirstName, LastName
INTO TestTable
FROM Person.Contact
WHERE EmailPromotion = 2
----Verify that Data in TestTable
SELECT FirstName, LastName
FROM TestTable
----Clean Up Database
DROP TABLE TestTable
Ref 1 2
It would work as given below :
insert into Gengl_Del Select Tdate,DocNo,Book,GlCode,OpGlcode,Amt,Narration
from Gengl where BOOK='" & lblBook.Caption & "' AND DocNO=" & txtVno.Text & ""
If the destination table does exist but you don't want to specify column names:
DECLARE #COLUMN_LIST NVARCHAR(MAX);
DECLARE #SQL_INSERT NVARCHAR(MAX);
SET #COLUMN_LIST = (SELECT DISTINCT
SUBSTRING(
(
SELECT ', table1.' + SYSCOL1.name AS [text()]
FROM sys.columns SYSCOL1
WHERE SYSCOL1.object_id = SYSCOL2.object_id and SYSCOL1.is_identity <> 1
ORDER BY SYSCOL1.object_id
FOR XML PATH ('')
), 2, 1000)
FROM
sys.columns SYSCOL2
WHERE
SYSCOL2.object_id = object_id('dbo.TableOne') )
SET #SQL_INSERT = 'INSERT INTO dbo.TableTwo SELECT ' + #COLUMN_LIST + ' FROM dbo.TableOne table1 WHERE col3 LIKE ' + #search_key
EXEC sp_executesql #SQL_INSERT
select *
into existing table database..existingtable
from database..othertables....
If you have used select * into tablename from other tablenames already, next time, to append, you say select * into existing table tablename from other tablenames
IF you want a identity column in new table created with select into then it can be done as below.
SELECT
ID = IDENTITY(INT, 1, 1),
name
INTO table2
FROM table1
If you want to insert into Table_A, from Table_B, only if the column is not in Table_A, then use the following:
BEGIN TRANSACTION
INSERT INTO dbo.Table_A (Column_1)
SELECT DISTINCT Some_Column AS Column_1
FROM dbo.Table_B
WHERE Some_Column
NOT IN (SELECT DISTINCT GroupId
FROM dbo.Table_A)
COMMIT
