DELETE Statement in the Last Request - Advanced SQL Engine - Teradata Database

If a DELETE statement is in the last request of a transaction and the following conditions are met, the delete is optimized to delete entire row partitions:

• The ANSI mode and Teradata mode conditions for fastpath delete processing are satisfied, with the exception that a deferred partition DELETE can be followed by another statement that references the same target table.
• The target table is not defined with referential integrity.
