-- Functionality: Union all with joins and aggregates, various joins,
--                subqueries with aggregates, correlated subqueries.
-- Expected files: EXPECTED002, EXPECTED002.MP
-- Table created: t002t1, t002t2, t002t3, t002temp, t002tmp2, t002t5,
--                t002t6, t002t7, t002t8, t002t9, t002t10, t002tab2,

-- View Created: t002v
-- Limitations:
-- To Do: - Table t002vt is not created in ifMX case, but is to be dropped.
--        - Remove DIFF002.KNOWN.NSK when Unicode is supported on MX tables
--          while Unicode may never be supported on MP tables
--          (Done 5/19/02)
-- Revision history:
--     (1/28/02) - Copied from fullstack/TEST002
--     (2/18/02) - Renamed tables ZZ, ZZI, FU, FUI to t002ZZ, t002ZZI,
--                 t002FU, t002FUI
--     (2/19/02) - Merged in fullstack/TEST002U
--     (2/20/02) - Moved most subquery tests to TEST002 (Core)
--     (3/04/02) - Comment off Unicode tests for MP tables
--     (5/19/02) - Removed DIFF002.KNOWN.NSK as unicode is supported.
