Set a SP return value to a variable in SQL Server

Question

I have a sproc that returns a single line and column with a text, I need to set this text to a variable, something like:

declare @bla varchar(100)
select @bla =          


        

Answer 1

If the stored procedure is returning a single value you could define one of the parameters on the stored procedure to be an OUTPUT variable, and then the stored procedure would set the value of the parameter

CREATE PROCEDURE dbo.sp_Name
    @In INT,
    @Out VARCHAR(100) OUTPUT

AS
BEGIN
    SELECT @Out = 'Test'
END
GO

And then, you get the output value as follows

DECLARE @OUT VARCHAR(100)
EXEC sp_name 1, @Out OUTPUT
PRINT @Out
