Assigning results of stored procedure to a variable

I have a stored procedure (usp_GetEmailsOnCall) that selects as varchar(250) a set of email address in a line (i.e. in the format fred.smith@domain.com;joe.bloggs@domain.com) for where the oncall column = 1.

In the under lying table they are in the format

Email OnCall

fred.smith@domain.com 1

joe.bloggs@domain.com 1

mary.jones@domain.com 0

I now want to assign this to a variable. In the past I’ve used

Exec @Var = usp_GetEmailsOnCall

To get this type of info but in this instance all I’m getting is zero.

After a couple of hours googling this I’m still none the wiser / nearer my answer.

Does anyone have the answer please

I have now got a work around by putting the results of the sp into a temp table then, as the data is always only one row, assigning the variable to being the select top 1 from the table.

This seems a bit clumsy, so if there is a more elegant solution I would still like to hear.

Many thanks

Stuart

Hi Stuart,

Try this:

CREATE PROCEDURE usp_GetEmailsOnCall



   @EmailsOnCall varchar(max) OUTPUT

AS

BEGIN

   SET @EmailsOnCall = 'fred.smith@domain.com;joe.bloggs@domain.com' -- Replace this with actual code to get email adresses from database table

END

GO

DECLARE @EmailsOnCall varchar (max)

EXEC usp_GetEmailsOnCall @EmailsOnCall OUTPUT

SELECT @EmailsOnCall

Note that both the declaration of the parameter in the procedure as well as the actual parameter passed when calling the SP must be flagged as OUTPUT.

Regards,

Jan

Thanks for that Jan, I'll give that a go

I can now see where in one of my attempts in doing it I went wrong. I didn't pass a parameter to the stored proc as output and I was expecting to jyst output the data - it makes sense now.

You live and learn (hopefully)
