如何在MySQL中启用严格的sql_mode?

How can I enable strict sql_mode in MySQL?

我想从SQL中获取数据并在strict模式下对其进行处理.

I want to fetch data from SQL and process the same in strict mode.

我当前的sql_mode是:

mysql> SELECT @@sql_mode;
+------------------------+
| @@sql_mode             |
+------------------------+
| NO_ENGINE_SUBSTITUTION |
+------------------------+

推荐答案

您基本上可以通过两种方法来执行此操作，即使用SQL命令或更改配置文件.如果使用SQL命令进行设置-服务器重新启动后，它会变回原来的状态.

You basically have two ways of doing it, using SQL command or changing configuration file. If you set it using SQL command - it will change back after the server is restarted.

在SQL中执行

SET GLOBAL sql_mode='STRICT_TRANS_TABLES';

在配置文件中执行此操作

Doing it in config file:

[mysqld] sql_mode="STRICT_TRANS_TABLES"

[mysqld] sql_mode="STRICT_TRANS_TABLES"

文件位置因您的操作系统而异，更多有关在此处找到文件的位置: https://dev.mysql.com/doc/refman/5.7/en/option-files.html

File location varies depending on your operating system, more on where to find it here: https://dev.mysql.com/doc/refman/5.7/en/option-files.html

重要的是，您可以指定多种模式:

Important to note, that you can have multiple modes specified:

sql_mode="STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION"

这在使用SQL语句时尤其重要，因为它可以覆盖整个模式字符串.

this is especially important when using SQL statement, since it could override your whole mode string.

有关SQL模式的更多信息，请参见: https://dev .mysql.com/doc/refman/5.7/en/sql-mode.html
