Update Query
How do you ensure a query matching 2 or more feilds in multiple tables has not fed back any duplicates?

RE: Update Query
Hi Daq
Firstly if you SQL is structured correctly you shouldn't return too many duplicates. However if you are getting duplicates there is an SQL command called DISTINCT.
Hope this helps
David
