Mysql has a nice “if exists” addition to the drop table statement. If the table to be dropped does not exists, it doesn’t raise an exception but only creates a warning.
In Oracle RDMBS you can emulate this behavior like so:
BEGIN EXECUTE immediate 'drop table INSERT_TABLE_NAME_HERE'; EXCEPTION WHEN others THEN IF SQLCODE != -942 THEN RAISE; END IF; END; /
Ugly, but it works very well.
