Hi Gurus,
Which is faster - a subquery or a join ?
select groupid,ob
jectid from egmemberobject
where groupid in (select groupid from eggroup where grouptype=2)
select a.groupid,a.objectid from egmemberobject a, eggroup b
where a.groupid=b.groupid
and b.grouptype=2
Could somebody please list or site examples of specific cases when you would
use one over the other despite the performance issues?
thanks,
