Re: Oracle : IF Exists

Hi

The most common way is to select from all_objects, all_tables, all_views. See the description of these views in the manual. They all map to Oracle's so-called data dictionary, which hold the medata about objects in the database.

The faster way will be to attempt the operation on the table and intercept the exception of ORA-942. To do it, you will need to enclose executed code into BEGIN..EXCEPTION...END block and possibly to define an exception with EXCEPTION_INIT. See your PLSQL guide for more information.
