Joining tables by more than one column

[cgosmon]

I have 2 tables that I need to merge. However I have to join two different columns from each table. For example, both tables have user id and date feilds that need to be joined. If I join by user id the date column does not line up on the merged table. Both tables have several instances of each that need to be group as the end result as well as other fields from each i need to keep. Any ideas anyone?

Turns out that the solution is pretty simple. Just hold down Ctrl and select the columns you want to join.
