# suite/funcs_1/datadict/is_tables.inc
#
# 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.

# TABLE_CATALOG (always shows NULL),
# TABLE_SCHEMA (shows the name of the database, or schema, in which an

# TABLE_NAME (shows the name of a table which the current user may access),
# TABLE_TYPE (shows whether the table is a BASE TABLE, a TEMPORARY table,
#       or a VIEW),
# ENGINE (shows the storage engine used for the table),
# VERSION (shows the version number of the table's .frm file),
# ROW_FORMAT (shows the table's row storage format; either FIXED, DYNAMIC
#       or COMPRESSED),
# TABLE_ROWS (shows the number of rows in the table),
# AVG_ROW_LENGTH (shows the average length of the table's rows),
# DATA_LENGTH (shows the length of the table's data file),
# MAX_DATA_LENGTH (shows the maximum length of the table's data file),
# INDEX_LENGTH (shows the length of the index file associated with the table),
# DATA_FREE (shows the number of allocated, unused bytes),
# AUTO_INCREMENT (shows the next AUTO_INCREMENT value, where applicable),
# CREATE_TIME (shows the timestamp of the time the table was created),
# UPDATE_TIME (shows the timestamp of the time the table's data file was
#       last updated),
# CHECK_TIME (shows the timestamp of the time the table was last checked),
# TABLE_COLLATION (shows the table's default collation),
# CHECKSUM (shows the live checksum value for the table, if any; otherwise NULL),
# CREATE_OPTIONS (shows any additional options used in the table's definition;
#       otherwise NULL),
# TABLE_COMMENT (shows the comment added to the table's definition;
#       otherwise NULL).
