TRUNCATE TABLE statement

Description 

If TRUNCATE_WITH_AUTO_COMMIT is set to ON, then a COMMIT is executed both before and after the TRUNCATE TABLE statement is executed. The primary purpose of the option is to enable faster table truncation (delete of all rows).

There are some cases where a fast TRUNCATE cannot be done:

• If there are foreign keys either to or from the table

• If the TRUNCATE TABLE statement is executed within a trigger

• If the TRUNCATE TABLE statement is executed within an atomic statement
