# suite/funcs_1/t/is_table_privileges.test
#
# Check the layout of information_schema.table_privileges 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.
