I want to import 100000 entries to my database. Each entry has mutiple columns, suppose 10 columns. There are some duplicates in them(sometimes according to (column1, column2), sometimes according to (column5, column6)).

How can I keep entries imported to database are unique on (column1, column2) and (column5, column6).

What's the best way to remove them(duplicates)?

Thanks in advance! Received on Tue Mar 13 2001 - 15:37:00 CST
