I can't tell from you SQL statement what you are trying to do.  Does this do
what you want?

SELECT * FROM groups WHERE grouptype=7 and datecreate>'2006-09-01'
order by groupid;

If not, then perhaps you need to use a subquery to get the primary key for the
rows that you want and then select those from the master table.
