# New test case for WL 3686 (which is not until CGE-6.3)

# but test is committed in 5.1 to verify consistant results.

#

# When only constant expressions in update statements and

# only PK or UK in WHERE clause. No extra WHERE parts are

# allowed. WL #3687 takes of more advanced variants of

# avoiding the read before the update/delete
