-any queries involving the three new tables fail
queries to work on multiple tables at once, despite the column
names being the same. But besides this:
My current version generates, for multi-select cases, queries like this:
DELETE FROM the_table WHERE `ID`='1' OR ID`='2' OR `ID`='3' OR `ID`='4' OR
`ID`='5' OR `ID`='6'
or similar
for each delete routine. I've still not suceeded in getting
the delete queries to work on multiple tables at once, despite the column
names being the same. But besides this:
Multi-table deletes are new to mySQL 4.0, so if you are running a 3.x release they
won't work.

Hi
apologies if this is a dumb question but can you do subqueries in mysql?
select count(*) as RES from ACL_USER_GROUP_ROLE as UGR where UGR.USER_ID
=2 and UGR.ROLE_ID = (select ROLE_ID from ACL_ROLE where ROLE_NAME =
'projectmanager' )
this query fails, but the individual queries work fine
, but the individual queries work fine
select count(*) as RES from ACL_USER_GROUP_ROLE as UGR where UGR.USER_ID
=2 and UGR.ROLE_ID = 3
and
select ROLE_ID from ACL_ROLE where ROLE_NAME = 'projectmanager'
cheers
Nathan
You need MySQl 4.1.x to do subqueries.
