# Test plan:
#
#   1.*: Test UPDATE ... FROM statements that modify IPK fields. And that
#        modify "INTEGER PRIMARY KEY" fields on WITHOUT ROWID tables.
#
#   2.*: Test UPDATE ... FROM statements that modify PK fields of WITHOUT
#        ROWID tables.
#
#   3.*: Test that UPDATE ... FROM statements are not confused if there
#        are multiple tables of the same name in attached databases.
#
#   4.*: Tests for UPDATE ... FROM statements and foreign keys.
