How to try to drop a table without raising exception ORA-00942: table or view does not exist


Joris Visscher

With the piece of code below it’s quite easy to first make sure your table exists before dropping it, so you’re not running into SQL Error: ORA-00942: table or view does not exist

Script explanation: It will check if the table is present before trying to drop it.

-- Drop table
DECLARE
 l_count NUMBER;
BEGIN
 SELECT COUNT(1)
 INTO l_count
 FROM ALL_TABLES
 WHERE table_name = 'TABLE_NAME'
 AND owner = 'USERNAME';
 IF l_count > 0 THEN
 EXECUTE IMMEDIATE 'Drop table USERNAME.TABLE_NAME CASCADE CONSTRAINTS';
END IF;
END;
