Just curious could I create a lookup table with all the extension in it and then insert that into the CallTrace table where the extension and do the same for the Customer table, because right now there are no PK, FK, it is the worst DB structure I have ever worked with, and yet they want miracles; After this I am going to insist on taking the time to work with my peer to begin creating a datamart, any suggestion for a beginning SQL to accomplish this?
