# suite/funcs_1/t/tables.test

#

# Check the layout of information_schema.tables and the impact of

# CREATE/ALTER/DROP TABLE/VIEW/SCHEMA ... on it.

#

# Note:

#    This test is not intended

#    - to show information about the all time existing tables

#      within the databases information_schema and mysql

#    - for checking storage engine properties

#      Therefore please do not alter $engine_type and $other_engine_type.

#      Some results of the subtests depend on the storage engines assigned.
