Hello,

This is closely linked to the already-answered PAQed question ["if not exists" SQL statement in Oracle ?] but you can have a new answer anyway ;-)

You have to use PL/SQL to write some kind of stored procedure :

Begin execute immediate 'Drop table toto'; Exception when others then null; End; / create table toto (...DDL...);



or you can also use this kind of code :

DECLARE exists PLS_INTEGER; BEGIN select count(*) into exists from user_tables where table_name = 'toto'; if exists = 1 then execute immediate 'drop table toto'; end if; END; / create table toto ( ...DDL...);
