# This file implements regression tests for SQLite library.  The
# focus of this file is is verifying that a virtual table in the
# TEMP database that is created and dropped within a transaction
# is handled correctly.  Ticket #2994.
#
# Also make sure a virtual table on the right-hand side of an IN operator
# is materialized rather than being used directly.  Ticket #3082.
