27# Test organization:
28#
29# alter-1.1.* - alter-1.7.*: Basic tests of ALTER TABLE, including tables
30#     with implicit and explicit indices. These tests came from an earlier
31#     fork of SQLite that also supported ALTER TABLE.
32# alter-1.8.*: Tests for ALTER TABLE when the table resides in an
33#     attached database.
34# alter-1.9.*: Tests for ALTER TABLE when their is whitespace between the
35#     table name and left parenthesis token. i.e:
36#     "CREATE TABLE abc       (a, b, c);"
37# alter-2.*: Test error conditions and messages.
38# alter-3.*: Test ALTER TABLE on tables that have TRIGGERs attached to them.
39# alter-4.*: Test ALTER TABLE on tables that have AUTOINCREMENT fields.
40# ...
41# alter-12.*: Test ALTER TABLE on views.
42#
43
44# Create some tables to rename.  Be sure to include some TEMP tables
45# and some tables with odd names.
