Oracle Create Table if it does not exist

Normally, it doesn't make a lot of sense to check whether a table exists or not because objects shouldn't be created at runtime and the application should know what objects were created at install time. If this is part of the installation, you should know what objects exist at any point in the process so you shouldn't need to check whether a table already exists.

If you really need to, however,

• You can attempt to create the table and catch the `ORA-00955: name is already used by an existing object" exception.
• You can query USER_TABLES (or ALL_TABLES or DBA_TABLES depending on whether you are creating objects owned by other users and your privileges in the database) to check to see whether the table already exists.
• You can try to drop the table before creating it and catch the `ORA-00942: table or view does not exist" exception if it doesn't.

You can do this with the Following Procedure -

BEGIN    BEGIN         EXECUTE IMMEDIATE 'DROP TABLE <<Your Table Name>>';    EXCEPTION         WHEN OTHERS THEN                IF SQLCODE != -942 THEN                     RAISE;                END IF;    END;    EXECUTE IMMEDIATE '<<Your table creation Statement>>';END;

Hope this may help you.

@Archie I would like to answer your question.@Piyas De Sorry for stealing your code :).

Just a little update of @Piyas De answer.

BEGIN    BEGIN        EXECUTE IMMEDIATE '<<Your table creation Statement>>';    EXCEPTION        WHEN OTHERS THEN            IF SQLCODE == -955 THEN                RAISE;            END IF;    END;END;
