sql server 2008 - set @var = exec stored_procedure

Question

Is it possible to assign at variable a value returned from exec stored procedure?

Something like

DECLARE @count int
SET @count = Execute dbo.usp_GetCount @Id=123

Answer 1

If you use RETURN in the proc

DECLARE @count int
EXECUTE @count = dbo.usp_GetCount @Id=123

OUTPUT parameter

DECLARE @count int
EXECUTE dbo.usp_GetCount @Id=123, @count OUTPUT

Redirect the results to temp table/table variable

DECLARE @count int
DECLARE @cache TABLE (CountCol int NOT NULL)
INSERT @cache EXECUTE dbo.usp_GetCount @Id=123
SELECT @count = CountCol FROM @cache

You can't assign a recordset from the stored proc directly to a scalar variable
