MySQL 5.7.9版本sql_mode=only_full_group_by问题
用到GROUP BY 语句查询时com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Expression #2 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'col_user_6.a.START_TIME' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by错误
解决方法 (修改全局):执行set global sql_mode = ''; 把sql_mode 改成非only_full_group_by模式。验证是否生效 SELECT @@GLOBAL.sql_mode 或 SELECT @@sql_mode
执行(只是修改会话级别的,只是当前会话生效)set session sql_mode = ''; 把sql_mode 改成非only_full_group_by模式。验证是否生效 SELECT @@GLOBAL.sql_mode 或 SELECT @@sql_mode
