Hi,

I have two tables A and B, each have a column dates, A.dates, B.dates. How to find out the part that is in B but not in A, or wise versa?

Thanks!

The reason is that A.dates is all dates in a month; B.dates is only weekdays. I want to mark the week days or weekends by another column: A.Weekends.

Use setdiff for that purpose.
