2 解决办法
2.1 查看全局sql模式
使用如下m命令：
|
1
|
select @@global.sql_mode; |
如下：
|
1
2
3
4
5
6
7
|
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) |
2.2 设置全局sql模式
使用如下命令：
|
1
|
SET GLOBAL sql_mode = 'STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION'; |
如下：
|
1
2
3
|
ysql> SET GLOBAL sql_mode = 'STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION';Query OK, 0 rows affected, 1 warning (0.00 sec)mysql> |
2.3 查看当前sql模式
使用如下命令：
|
1
|
select @@sql_mode; |
如下：
|
1
2
3
4
5
6
7
8
|
mysql> select @@sql_mode;+------------------------------------------------------------------------------------------------------------------------+| @@sql_mode |+------------------------------------------------------------------------------------------------------------------------+| 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> |
2.4 设置当前sql模式
使用如下命令：
|
1
|
set @@sql_mode = 'STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION'; |
如下：
|
1
2
3
|
mysql> set @@sql_mode = 'STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION';Query OK, 0 rows affected, 1 warning (0.00 sec)mysql> |
3 永久生效的解决办法
3.1 找到my.cnf文件
可以使用如下命令查找，一般在 /etc/下或者 /etc/mysql/ 目录下
|
1
|
find /etc/ -name my.cnf |
3.2 编辑my.cnf文件
|
1
|
vi /etc/mysql/my.cnf |
然后增加以下内容：
|
1
|
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION |
3.3 重启数据库服务
|
1
|
systemctl restart mysqld |
