    11  # This file implements regression tests for SQLite library.  The
    12  # focus of this file is is verifying that a virtual table in the
    13  # TEMP database that is created and dropped within a transaction
    14  # is handled correctly.  Ticket #2994.
    15  #
    16  # Also make sure a virtual table on the right-hand side of an IN operator
    17  # is materialized rather than being used directly.  Ticket #3082.
