# Bug#20691: DATETIME col (NOT NULL, NO DEFAULT) may insert garbage when specifying DEFAULT
#
# From the docs:
#  If the column can take NULL as a value, the column is defined with an
#  explicit DEFAULT NULL clause. This is the same as before 5.0.2.
#
#  If the column cannot take NULL as the value, MySQL defines the column with
#  no explicit DEFAULT clause. For data entry, if an INSERT or REPLACE
#  statement includes no value for the column, MySQL handles the column
#  according to the SQL mode in effect at the time:
#
#    * If strict SQL mode is not enabled, MySQL sets the column to the
#      implicit default value for the column data type.
#
#    * If strict mode is enabled, an error occurs for transactional tables and
#      the statement is rolled back. For non-transactional tables, an error
#      occurs, but if this happens for the second or subsequent row of a
#      multiple-row statement, the preceding rows will have been inserted.
