mysql5.7 datetime 默認值0000-00-00 00:00:00出錯
實驗環境:MySQL 5.7.17
使用wordpress的表wp_posts
mysql > CREATE TABLE `wp_posts` ( -> `ID` bigint(20) unsigned NOT NULL AUTO_INCREMENT, -> `post_author` bigint(20) unsigned NOT NULL DEFAULT '0', -> `post_date` datetime NOT NULL DEFAULT '0000-00-00 00:00:00', -> `post_date_gmt` datetime NOT NULL DEFAULT '0000-00-00 00:00:00', -> `post_content` longtext NOT NULL, -> `post_title` text NOT NULL, -> `post_excerpt` text NOT NULL, -> `post_status` varchar(20) NOT NULL DEFAULT 'publish', -> `comment_status` varchar(20) NOT NULL DEFAULT 'open', -> `ping_status` varchar(20) NOT NULL DEFAULT 'open', -> `post_password` varchar(20) NOT NULL DEFAULT '', -> `post_name` varchar(200) NOT NULL DEFAULT '', -> `to_ping` text NOT NULL, -> `pinged` text NOT NULL, -> `post_modified` datetime NOT NULL DEFAULT '0000-00-00 00:00:00', -> `post_modified_gmt` datetime NOT NULL DEFAULT '0000-00-00 00:00:00', -> `post_content_filtered` longtext NOT NULL, -> `post_parent` bigint(20) unsigned NOT NULL DEFAULT '0', -> `guid` varchar(255) NOT NULL DEFAULT '', -> `menu_order` int(11) NOT NULL DEFAULT '0', -> `post_type` varchar(20) NOT NULL DEFAULT 'post', -> `post_mime_type` varchar(100) NOT NULL DEFAULT '', -> `comment_count` bigint(20) NOT NULL DEFAULT '0', -> PRIMARY KEY (`ID`), -> KEY `post_name` (`post_name`(191)), -> KEY `type_status_date` (`post_type`,`post_status`,`post_date`,`ID`), -> KEY `post_parent` (`post_parent`), -> KEY `post_author` (`post_author`) -> ) ENGINE=innodb AUTO_INCREMENT=536 DEFAULT CHARSET=utf8; ERROR 1067 (42000): Invalid default value for 'post_date'
出現以上問題:是因為mysql5.7版本后,sql_mode參數被設置了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)
解決方法:
方法一:臨時修改方法
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' ;
方法二:永久修改方法,需要重啟mysql服務:修改mysql的配置文件my.cnf,添加以下參數
sql_mode=ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION //實際是去除NO_ZERO_IN_DATE,NO_ZERO_DATE
方法三:修改datetime的默認值
