when trying to run an sql 2005 user defined function, it wont execute as the following error message occurs:

Msg 443, Level 16, State 15, Procedure InsertMailingPreferences, Line 60
Invalid use of side-effecting or time-dependent operator in 'INSERT' within a function.

How do i resolve this?

THanks

You can't run DML statements on user tables inside functions like that.

Chap is right... but what you really want is a stored procedure.
USE [MembershipDB]
GO
/****** Object:  procedure[dbo].[getUpgradeProductIdInPackage]    Script Date: 10/27/2008 14:09:44 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
create procedure [dbo].[InsertMailingPreferences] 
                        
                        @PackageID int,
                        @AddressID int,
                        @UserName nvarchar(100)
                        @output nvarchar(50) output

Thanks,

but this function is the second call, after a stored procedure, which then calls another function as you can see.

The problem is, when i convert the above function to a strored procecure, i cant call it from another stored procedure...or can i?

Thanks
