mysql 查询报错

Expression #1 of ORDER BY clause is not in SELECT list, references column 'X1.t0.name' which is not in SELECT list; this is incompatible with DISTINCT

这一般是mysql版本问题造成的。

临时解决：

select version();
select @@global.sql_mode   查询sql_mode
set global sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION';

永久解决：
修改my.cnf，去掉ONLY_FULL_GROUP_BY参数:
添加sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION

数据库表字段字符集不同的查询报错，首先查看创建表的sql，或者看表结构的字符集是什么样子，然后修改一致，

ALTER table table_name COLLATE=utf8mb4_general_ci, convert to CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;
