CREATE FUNCTION [dbo].[tvf_StoredProcedureParameter]
( 
    @StoredProcedureName SYSNAME 
)
RETURNS @Parameters TABLE ( 
    [Parameter Name] SYSNAME,
    [Data Type] SYSNAME,
    [Length] INT,
    [Scale] INT,
    [Direction] NVARCHAR(20) 
    )
AS
BEGIN
   INSERT INTO @Parameters 
   SELECT PARAMETER_NAME,DATA_TYPE,ISNULL(CHARACTER_MAXIMUM_LENGTH, NUMERIC_PRECISION),NUMERIC_SCALE,PARAMETER_MODE FROM INFORMATION_SCHEMA.PARAMETERS
   WHERE SPECIFIC_SCHEMA = 'dbo' AND  SPECIFIC_NAME = @StoredProcedureName
   ORDER BY ORDINAL_POSITION
