Read all about Join in the manual -- it includes hints like this query:
SELECT DISTINCT(PersonID) FROM PersonProject AS P1
LEFT JOIN PersonProject AS P2 ON P2.PersonID=P1.PersonID AND
P2.ProjectID=2
WHERE P2.PersonID IS NULL;
Cheers,
Kent
That is exactly what I want, Thanks Rafal
PS: does anybody know if there are plans to support nested queries in mySQL?
Hi,
maybe something like this:
select a.PersonId from PersonProject a left join PersonProject b
on(a.PersonID=b.PersonID and b.ProjectID=2) where b.PersonID
is null group

I am using two versions of MySQL, on two different platforms, and having the
same problem on both. One very odd aspect of this problem is that it behaves
precisely the same way on both platforms, down to which records are garbled
onscreen and how they are garbled. Anyone with any ideas?

Are you inserting both values at once? Or inserting the startdate first,
then
updating the stopdate later. You may or may not be able to do this in one
