CREATE OR REPLACE TABLE

Question

Hi, i need to write a script that re-creates a table. Something similar to CREATE OR REPLACE VIEW. I came up with the following
DECLARE
   does_not_exist   EXCEPTION;
   PRAGMA EXCEPTION_INIT (does_not_exist, -942);
BEGIN
   EXECUTE IMMEDIATE 'DROP TABLE foobar';
EXCEPTION
   WHEN does_not_exist
   THEN
      NULL;
END;
CREATE TABLE foobar (c1 INT);I wonder if there's an easier way. Is there?
TIA, Markus

Hi, Markus,
I don't know of anything simpler.
In SQL*Plus, you can do something that's about as complicated:
SET     PAGESIZSE     0
SPOOL     next_step.sql
SELECT     CASE
          WHEN  ( SELECT  1
                     FROM     user_tables
               WHERE     table_name     = 'FOOBAR'
          THEN  'DROP TABLE FOOBAR;'
          ELSE  'PROMPT  Table did not exist'
     END
FROM     dual;
SPOOL     OFF
@next_stepAll this supposes you really need something that doesn't raise an error.
