Unanswered: Cascade Delete And Update
Im a mysql newbie, my problem is sounds easy to all mysql experts. I used mysql 5.0.1 beta. It is posible to to have a cascade delete and update here.
ok i have to give 2 tables here.
if i delete idno 0001 in table1 . The corresponding record in table2 also where delete.
In Ms SQL it is posible.
Another question is, what is the diferent between unique and primary index?
yes, you can have CASCADE, but you must use InnoDB tables for this
the difference between unique and primary keys is that unique keys can be null
thanks for the answer bro.
