[Err] 1055 - Expression #1 of ORDER BY clause is not in GROUP BY clause and contains nonaggregated c

在navicat for mysql中的查询编辑器中执行sql语句总是提示下面的错误,虽然也可以正确的执行,但是看着总有些不对劲,所以就在csdn上查找了解决方案:已验证此解法可以有效。

[Err] 1055 - Expression #1 of ORDER BY clause is not in GROUP BY clause and contains nonaggregated c

解决方法:

主要是因为sql_mode设置导致的这个错误。

在新建查询中执行如下命令:

 
  1. -- 查看sql_mode设置

  2. show variables like "sql_mode";

  3. -- 设置sql_mode

  4. set sql_mode='';

  5. set sql_mode='NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES';

结果证明该方案有效;

[Err] 1055 - Expression #1 of ORDER BY clause is not in GROUP BY clause and contains nonaggregated c

 

也可以参考博主的另一个方法,设置mysql中的my.ini文件。
