I am not going to deep into the details but I need a way to determined the type of the return columns by store procedure.
Is there a way to achieved that and I do not look for a solution that works with specified procedure - I should be able to detect this in other procedure that receive as parameter other procedure's name.
I am using SQL Server 2012.
In SQL Server 2012 you can use sp_describe_first_result_set
As the name implies this returns metadata about the first result set only returned by a stored procedure. Example below.
CREATE PROC Foo
AS
SELECT *
FROM sys.objects
GO
EXEC sp_describe_first_result_set @tsql = N'Foo'
