Adding the index is definitely not the solution, nonethelesst an index on Deleted() is always a good idea.

>>Index uniqueness violated. I checked all fields and the values are in fact unique. Other info..the two tables are related thru another field called orderid...just thought that I might need another index on that one "for not dele()"...stay tuned...//:^)
>That was it. I needed the "for not dele()" clause on my relation index. Now the problem is that since I have cascading deletes, the delete and insert update is deleting my child records, but not adding them back in. Can I temporarily "turn off" the cascading delete?
