# This file implements regression tests for SQLite library.

# This file implements tests to verify that ticket [31338dca7e] has been
# fixed.  Ticket [31338dca7e] demonstrates problems with the OR-clause
# optimization in joins where the WHERE clause is of the form
#
#     (x AND y) OR z
#
# And the x and y subterms from from different tables of the join.
