How to execute a stored procedure inside a select query - sql

Question

SELECT col1,
col2,
col3,
EXEC GetAIntFromStoredProc(T.col1) AS col4
FROM Tbl AS T
WHERE (col2 = #parm)
How to write this SQL query in SQL Server 2008?

Answer 1

Thanks #twoleggedhorse.
Here is the solution.
First we created a function
CREATE FUNCTION GetAIntFromStoredProc(#parm Nvarchar(50)) RETURNS INTEGER
AS
BEGIN
DECLARE #id INTEGER
set #id= (select TOP(1) id From tbl where col=#parm)
RETURN #id
END
then we do the select query
Select col1, col2, col3,
GetAIntFromStoredProc(T.col1) As col4
From Tbl as T
Where col2=#parm

Functions are easy to call inside a select loop, but they don't let you run inserts, updates, deletes, etc. They are only useful for query operations. You need a stored procedure to manipulate the data.
So, the real answer to this question is that you must iterate through the results of a select statement via a "cursor" and call the procedure from within that loop. Here's an example:
DECLARE #myId int;
DECLARE #myName nvarchar(60);
DECLARE myCursor CURSOR FORWARD_ONLY FOR
SELECT Id, Name FROM SomeTable;
OPEN myCursor;
FETCH NEXT FROM myCursor INTO #myId, #myName;
WHILE ##FETCH_STATUS = 0 BEGIN
EXECUTE dbo.myCustomProcedure #myId, #myName;
FETCH NEXT FROM myCursor INTO #myId, #myName;
END;
CLOSE myCursor;
DEALLOCATE myCursor;
Note that ##FETCH_STATUS is a standard variable which gets updated for you. The rest of the object names here are custom.

Answer 3

You can create a temp table matching your proc output and insert into it.
CREATE TABLE #Temp (
Col1 INT
)
INSERT INTO #Temp
EXEC MyProc

Answer 4

As long as you're not doing any INSERT or UPDATE statements in your stored procedure, you will probably want to make it a function.
Stored procedures are for executing by an outside program, or on a timed interval.

Answer 5

"Not Possible".
You can use a function instead of the stored procedure.

Answer 6

"Not Possible". You can do this using this query.
Initialize here
declare #sql nvarchar(4000)=''
Set Value & exec command of your sp with parameters
SET #sql += ' Exec spName #param'
EXECUTE sp_executesql #sql, N'#param type', #param = #param

Answer 7

Don't forget, if you just want to use the SP as a one-off query real quick to check something, all you have to do is pull the innards of the SP out and paste it in a new query window and do whatever you like at that point because it is no longer a SP.

Create a dynamic view and get result from it.......
CREATE PROCEDURE dbo.usp_userwise_columns_value
(
#userid BIGINT
)
AS
BEGIN
DECLARE #maincmd NVARCHAR(max);
DECLARE #columnlist NVARCHAR(max);
DECLARE #columnname VARCHAR(150);
DECLARE #nickname VARCHAR(50);
SET #maincmd = '';
SET #columnname = '';
SET #columnlist = '';
SET #nickname = '';
DECLARE CUR_COLUMNLIST CURSOR FAST_FORWARD
FOR
SELECT columnname , nickname
FROM dbo.v_userwise_columns
WHERE userid = #userid
OPEN CUR_COLUMNLIST
IF ##ERROR <> 0
BEGIN
ROLLBACK
RETURN
END
FETCH NEXT FROM CUR_COLUMNLIST
INTO #columnname, #nickname
WHILE ##FETCH_STATUS = 0
BEGIN
SET #columnlist = #columnlist + #columnname + ','
FETCH NEXT FROM CUR_COLUMNLIST
INTO #columnname, #nickname
END
CLOSE CUR_COLUMNLIST
DEALLOCATE CUR_COLUMNLIST
IF NOT EXISTS (SELECT * FROM sys.views WHERE name = 'v_userwise_columns_value')
BEGIN
SET #maincmd = 'CREATE VIEW dbo.v_userwise_columns_value AS SELECT sjoid, CONVERT(BIGINT, ' + CONVERT(VARCHAR(10), #userid) + ') as userid , '
+ CHAR(39) + #nickname + CHAR(39) + ' as nickname, '
+ #columnlist + ' compcode FROM dbo.SJOTran '
END
ELSE
BEGIN
SET #maincmd = 'ALTER VIEW dbo.v_userwise_columns_value AS SELECT sjoid, CONVERT(BIGINT, ' + CONVERT(VARCHAR(10), #userid) + ') as userid , '
+ CHAR(39) + #nickname + CHAR(39) + ' as nickname, '
+ #columnlist + ' compcode FROM dbo.SJOTran '
END
EXECUTE sp_executesql #maincmd
END
-----------------------------------------------
SELECT * FROM dbo.v_userwise_columns_value
