1. 错误提示
[ERR] 1292 - Incorrect datetime value: '0000-00-00 00:00:00' for column 'created_at' at row 1
2. 问题分析
- 从上面的描述我们可以看出原因是:我们给类型是datetime的xxx字段赋值0000-00-00 00:00:00是不被支持的,赋值包含两种情况:
- 情况一:我们运行的sql文件直接提供的值就是0000-00-00 00:00:00
- 情况二:xxx字段我们没有提供值,默认值是0000-00-00 00:00:00
3. 原因分析
原因是我们的数据库不支持datetime为0的情况,这是一个模式的设置。
4. 具体解决
4.1 查看sql_mode
# 查看当前sql_modeselect @@sql_mode;# 查看全局sql_modeselect @@global.sql_mode;
4.2 显示结果:
mysql> select @@sql_mode;+-------------------------------------------------------------------------------------------------------------------------------------------+| @@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 (0.00 sec)
mysql> select @@global.sql_mode;+-------------------------------------------------------------------------------------------------------------------------------------------+| @@global.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 (0.00 sec)
mysql>
4.3 修改sql_mode(将上述查询到的sql_mode中的NO_ZERO_DATE和NO_ZERO_IN_DATE删除即可)
# 修改全局set @@global.sql_mode = 'ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';# 修改当前set @@sql_mode = 'ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';
