# This file implements regression tests for SQLite library.

# This file implements tests to make sure expression of an INSERT
# and UPDATE statement are only evaluated once. See ticket #980.
# If an expression uses a function that has side-effects or which
# is not deterministic (ex: random()) then we want to make sure
# that the same evaluation occurs for the actual INSERT/UPDATE and
# for the NEW.* fields of any triggers that fire.
