# 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.
