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