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
return
end
go
