So you'd rather have no foreign key relationships and let the DB get all out of whack rather than figure out the DTS issues? I think you're looking at the wrong problem, I'd spend my time figuring out the DTS and making sure it works correctly.

Speaking of OT SQL help ...
If there are any database gurus out there that could throw me a bone and send me some sql code that would detect and remove foreign key relationships from tables (sql server 2000). If you're thinking "why would I want to do this?" it is because this database gets updated everyday with DTS and the if anything is out of whack of course it causes DTS errors when moving the data.
I know I can remove them one at a time with enterprise manager but my remote connection seems to be incredibly slow doing it. 

Thanks,

Teddy,
Any idea why do I get an error in Query Analyzer :

SQL Statement
SELECT     *
FROM         dbo.ORDER_ITEMS oi LEFT OUTER JOIN
                      dbo.AP_translation tr ON tr.option_id IN
(select convert(int,Value) from dbo.Split(oi.OptionIDs, ','))
WHERE     (oi.Order_ID = 12387)

Error received:
Server: Msg 170, Level 15, State 1, Line 4
Line 4: Incorrect syntax near '.'.

You use it in an adhoc query in query analyzer or SSMA. I have not tried it as an ad hoc query in CF as I myself tend not to use cfquery wherever I can.

Without creating a SP, can I use this in a select statement?

Paul,
There is already an open source function in SQL Server to do this for you: 

http://www.4guysfromrolla.com/webtech/031004-1.shtml

They explain how to put it together.
Here is the function creation for how I put it together from their explanation:
if exists (select * from dbo.sysobjects where id = object_id (N'[dbo].[Split]') and xtype in (N'FN', N'IF', N'TF')) 
drop function [dbo].[Split]
GO

SET QUOTED_IDENTIFIER OFF
GO
SET ANSI_NULLS OFF
GO


CREATE  FUNCTION dbo.Split
(
 @List nvarchar(4000),
 @SplitOn nvarchar(5)
)

RETURNS @RtnValue table
(

 Id int identity(1,1),
 Value nvarchar(250)
)

AS

BEGIN

 While (Charindex(@SplitOn,@List)>0)
 Begin

  Insert Into
   @RtnValue
    (
    value
   )
  Select
Value = ltrim(rtrim(Substring(@List,1,Charindex (@SplitOn,@List)-1)))
Set @List = Substring(@List,Charindex(@SplitOn,@List)+len (@SplitOn),len(@List)) 
 End

 Insert Into
  @RtnValue
  (
   Value
  )
 Select
  Value = ltrim(rtrim(@List))

 Return

END

GO
SET QUOTED_IDENTIFIER OFF
GO
SET ANSI_NULLS ON
GO

It is implemented as such:

CREATE PROCEDURE getEmployeesByID(@employeeList nvarchar(1000))
AS

Select
   employeeId, -- integer (int)
   FirstName,
   LastName
from #myTable
Where
employeeId IN (Select convert(int,Value) from dbo.Split (@employeeList,',')) 


Cheers,
Teddy

I apologize for the OT post, but I'm getting frustrated.
I am attempting to use a UDF to split a varchar (comma delimited list of ints) in an IN clause in a SQL statement, and I'm not able to get the SQL statement to pass a Table field to the UDF.
I'm hoping someone sees a glaring error, or can tell me I can't do this.

OptionIDs is a varchar(255) field with a comma delimited list of integers. It doesn't like the oi.OptionIDs. If I put in a list like '0,1,2' in it's place, the query works. 

Can I not pass a field into a UDF?
Is there another way to skin this cat?
