Datetime, and Timestamp values Warning: By default zero date/datetime/timestamp values are no longer allowed in MySQL, as of 5.7.8 NO_ZERO_IN_DATE and NO_ZERO_DATE are included in SQL_MODE by default. These modes should be used with strict mode as they will be merged with strict mode in a future release. If you do not include these modes in your SQL_MODE setting, you are able to insert date/datetime/timestamp values that contain zeros. It is strongly advised to replace zero values with valid ones, as they may not work correctly in the future.
