Derived tables are an optional feature that you can specify in the FROM clause of SELECT, ABORT, ROLLBACK, and DELETE statements.

You can use derived tables for these purposes:
  • To avoid CREATE TABLE and DROP TABLE statements for storing retrieved information that is only needed for one request.
  • To enable you to code more sophisticated, complex join queries.

    For examples, see Inner Joins and Outer Joins.
