It is impossible in SQL.

You can not DELETE or INSERT or UPDATE more than one table in a single statement (exclusion is using OUTPUT clause which allows to insert results of modification operation into separate table).

Actually what is the reason you want to delete from two table in single statement? If it's to maintain data consistency, than just do your deletes in single transaction.

thanks sscrazy.........!!!!

it's a quick response.

There is nothing about consistency......... its just a question that someone asked me to do so..... he says its possible....!!!!

Trigger,OUTPUT, cascading are possible solution but i dont have to use none of them,,,,,,,!!! i guess MySQL has this capability......

I guess,,,,, it can be done.....!!!!

The only thing you can do is run the two delete statements inside a single transaction. Then, the data gets deleted, effectively, together and at the same time. But the delete statements themselves are two different deletes. As long as they're wrapped inside a transaction though, they'll complete or rollback as a single unit.
