I would expect that what you have should work.

create procedure t1
as
	raiserror('this is my error', 16, 1)
go

create procedure t 
	@p int output
as
	execute t1
	if @@error != 0
		set @p = -1
	else
		set @p = 0

return
go

declare @x int
execute t @x output
select @x

Are you finding the error in the Connection object's error collection?

>Basically, the statement of UPDMAIN1 will generate a duplicate primary key error. The result of ASP showed BLANK value of "RTNVALUE" and "@Err". And UPDMAIN1 storedproc is a common stored procedure to share another procedure. Anyone has any idea? Thank you for your help ....
