Hi All,
I am wondering if this is possible.
I understand how to create a variable within my query - when I am assigning a value from a table query to the variable. However I am wondering is it possible to instead of pulling the value from a query to actually pull it from a stored procedure?

For Example:
DECLARE  @Payout  Float

SELECT @Payout = SUM(revenue)
FROM
(EXEC  [dbo].[mystoredprocedure] '2014-09-01','2014-10-01')SUBQ

SELECT @Payout

Thank you,
P

I think I may have answered my own question.
By doing the following it allowed me to call the procedure.

DECLARE  @Payout  Float
EXEC @Payout  =[mystoredprocedure] '2014-09-01','2014-10-01'

hope this can help someone else.

Actually I didn't!
That only returned all the rows from the SP. Instead of the actual value I needed

DECLARE  @Payout Float
SELECT @Payout = Payout
EXEC @Payout =[mystoredprocedur] @fromdate,@todate

Hello,

if you can user the temp table you can store the values to temp table and then assign it to your parameter i.e.

DECLARE @Payout Float

CREATE TABLE #tmpvalue
(
    TEMPpayout float
)
INSERT INTO #tmpvalue(TEMPpayout )
EXEC dbo.mystoredprocedur @fromdate,@todate

SELECT
    @Payout = TEMPpayout 
FROM 
    #tmpvalue

Open in new window

As samo4fun noted, you can't do that directly.

Another possibility: add optional parameters to the proc to "tell" it to return only the total, and then use those params when you EXEC the proc:


CREATE PROCEDURE  mystoredprocedure
    @...existing params...,
    @return_revenue_total_only bit = 0,
    @revenue_total float = 0 OUTPUT
AS
...existing proc code...
IF @return_revenue_total_only = 1
    SELECT @revenue_total = SUM(revenue) FROM (...existing SELECT to return result set from proc...)
ELSE
    ...existing SELECT to return result set from proc...
GO



DECLARE @Payout  Float
EXEC  [dbo].[mystoredprocedure] '2014-09-01','2014-10-01', @return_revenue_total_only = 1,
    @revenue_total = @Payout OUTPUT

thank you both for the feedback. I ended up using a global variable and that seemed to do the trick.
