#
# The problem in ticket #2640 was that the query optimizer was
# not recognizing all uses of tables within subqueries in the
# WHERE clause. If the subquery contained a compound SELECT,
# then tables that were used by terms of the compound other than
# the last term would not be recognized as dependencies.
# So if one of the SELECT statements within a compound made
# use of a table that occurs later in a join, the query
# optimizer would not recognize this and would try to evaluate
# the subquery too early, before that tables value had been
# established.
