Edit File: mysql56_temporal_format_func.test

#
# This test checks that DATETIME, DATETIME(5), TIME(5) columns
# occupy different data length depending on @@mysql56_temporal_format:
#
#  Type           MariaDB   MySQL
#  ----           -------   -----
#  DATETIME             8       5
#  DATETIME(5)          7       8
#  TIME(5)              5       6
#
# The DATETIME(1-3,4,6) and TIME(0-4,6) data types use the same size
# in both MariaDB and MySQL formats.
# TIMESTAMP(0-6) also uses the same size in both formats.
#
# We use two columns in the tests below, to make sure the record length
# is longer than 7. Records whose fields occupy less then 7 bytes use
# 7 bytes anyway (assuming the default MAX_ROWS values), to store deleted
# record list pointers.
