Question

Using TSQL is there a way to determine whether a UDF returns a Scalar Value or a Table Value?

I examined the results of this query but could not see any differences in functions based on type:

select * from sysobjects where type = 'FN'

Thanks.

Answer 1

have you tried joining to sys.parameters

select * FROM sys.objects AS SO
INNER JOIN sys.parameters AS P 
ON SO.OBJECT_ID = P.OBJECT_ID where type = 'FN'

The type_desc column should be either SQL_SCALAR_FUNCTION or SQL_TABLE_VALUED_FUNCTION
