ORDER BY clause is not in SELECT list

1、mysql查询异常：

Error querying database. Cause: java.sql.SQLException: Expression #1 of ORDER BY clause is not in SELECT list, references column ‘xxx-数据库.T1.sort’ which is not in SELECT list; this is incompatible with DISTINCT

2、解决办法：

2.1、查看是否开启了only_full_group_by规则校验

SELECT @@GLOBAL.sql_mode;
查询结果:
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

SELECT @@SESSION.sql_mode;
查询结果:
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

2.2、关闭only_full_group_by的规则校验

单引号中的内容是第一步查询的结果去掉“ONLY_FULL_GROUP_BY,”之后的值
set @@GLOBAL.sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';
set @@SESSION.sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';
