# |
# alter3-1.*: Test that ALTER TABLE correctly modifies the CREATE TABLE sql. |
# alter3-2.*: Test error messages. |
# alter3-3.*: Test adding columns with default value NULL. |
# alter3-4.*: Test adding columns with default values other than NULL. |
# alter3-5.*: Test adding columns to tables in ATTACHed databases. |
# alter3-6.*: Test that temp triggers are not accidentally dropped. |
# alter3-7.*: Test that VACUUM resets the file-format. |
# |
|
# This procedure returns the value of the file-format in file 'test.db'. |
