MYSQL报错：1055 - Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column

1055 - Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column
'rpacloudsit.t.app_id' which is not functionally dependent on columns in GROUP BY clause;
this is incompatible with sql_mode=only_full_group_by

MySQL有any_value(field)函数，他主要的作用就是抑制ONLY_FULL_GROUP_BY值被拒绝

官方有介绍，地址：https://dev.mysql.com/doc/refman/5.7/en/miscellaneous-functions.html#function_any-value

我们可以把select语句中查询的属性（除聚合函数所需的参数外），全部放入any_value(field)函数中；

例如：select name,any_value(sex) from test_table group by name

这样sql语句不管是在ONLY_FULL_GROUP_BY模式关闭状态还是在开启模式都可以正常执行，不被mysql拒绝。
