Answer 1

You can do multiple table deletes:-

http://dev.mysql.com/doc/refman/5.0/en/delete.html

For example say you had 4 tables and want to delete all the records in 3 of them that relate to the 1st table:-

DELETE Table1, Table2, Table3
FROM Table0
INNER JOIN Table1
ON Table0.Id = Table1.ParentId
INNER JOIN Table2
ON Table0.Id = Table2.ParentId
INNER JOIN Table3
ON Table0.Id = Table3.ParentId
WHERE Table0.Id = 1

Of course you could also delete from the first table (Table0) as well.
