How can I get a list of all
select distinct PersonID
from PersonProject
where ProjectID != '2';

No, what I'm looking for is...
SELECT PersonID
FROM PersonProject
AND PersonID NOT IN (SELECT PersonID
FROM PersonProjectID
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
