Hi, not sure if you solved this problem but in case you have not I might suggest the following as possible reasons for Oracles error as the syntax looks good to me:

- Lack of Delete privs on the tables

As an aside to your specific question, if the tables that you are deleting are large tables - you should consider executing COMMIT inside your loop every 1000 of records to avoid "blowing" your rollback segments.

Debasisdas is correct skkydiver, there is one too many ; in the statement. we can reproduce this nicely
