I have a table with three simple columns: id(unique), memberID, and
choice
I want to find out which memberIDs have BOTH choice 2 AND choice 3.
--> SELECT memberID from table where choice=2 AND choice = 3
That won't work (0 results, of course, because no row has two choices,
they're mutually exclusive)
---> SELECT memberID from table where choice=2 OR choice = 3
That doesn't work (shows all memberIDs that chose either 2 or 3).
Can I maybe join the table upon itself on the memberID?
Other suggestions?
thanks,
bill hollett
