The best way if to use Cascaded Deletes[^], so that the database will always handle it for you.

Alternatively, I would suggest that using transactions might be a better alternative, possibly inside a stored procedure.

If the tables are related (i.e., they have a common key), you can use ON DELETE CASCADE clause in the foreign key specification. Deleting rows from a master table will result in the deletion of all related child rows from the dependant tables.

If the tables are not related, you must use multiple DELETE statements.
