在mysql5.5升级到5.7 或8.0 ，数据库默认sqlMode 是默认only\_full\_group\_by，导致聚合SQL报错

#### SQL: select a.deptname,ROUND(sum(a.outdata)\*0.0001,2) outPolicy,ROUND(sum(a.innerdata)\*0.0001,2) innerPolicy from( ( SELECT (case sd.pid when ‘1067246875800000066’ then sd.id else sd.pid end ) deptid, (case sd.pid when ‘1067246875800000066’ then sd.name else ####

#### Cause: java.sql.SQLSyntaxErrorException: Expression \#1 of SELECT list is not in GROUP BY clause and contains nonaggregated column ‘a.deptname’ which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql\_mode=only\_full\_group\_by ####

解决办法
    修改配置文件my.cnf

找到my.cnf，添加一下配置：

sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION

重启mysql即可。  
service mysqld restart
