The above problem occurs because after the mysql5.7 version, the sql_mode parameter is set to NO_ZERO_IN_DATE,NO_ZERO_DATE
Mysql > show variables like 'sql_mode' +- -- + | Variable_name | Value | +- -- +- -+ | sql_mode | ONLY_FULL_GROUP_BY STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER NO_ENGINE_SUBSTITUTION | +-+- -- + 1 row in set (0.01 sec)
Solution:
Method 1: temporarily modify the method
Mysql > set global sql_mode='ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'; mysql > set session sql_mode='ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'
Method 2: permanently modify the method, which requires restarting the mysql service: modify the configuration file my.cnf of mysql and add the following parameters
Sql_mode=ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION / / actually removes NO_ZERO_IN_DATE,NO_ZERO_DATE
Method 3: modify the default value of datetime
