MySQL 5.7版本sql_mode=only_full_group_by問題
1、在MySQL環境下執行分組sql,如下
mysql> select db_server_name,login_user,count(db_server_name) from `mysql_audit_log` group by login_user;
提示
ERROR 1055 (42000): Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column ‘collect_mysql_audit_log.mysql_audit_log.db_server_name‘ which is not functionally dependent on colum ns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
2、解決:
執行SELECT @@GLOBAL.sql_mode 查看
mysql> SELECT @@GLOBAL.sql_mode; +-------------------------------------------------------------------------------------------------------------------------------------------+ | @@GLOBAL.sql_mode | +-------------------------------------------------------------------------------------------------------------------------------------------+ | 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 | +-------------------------------------------------------------------------------------------------------------------------------------------+
1 row in set (0.06 sec)
重新設置 sql_mode,禁用ONLY_FULL_GROUP_BY。如下設置,下面設置是臨時生效,如果想永久生效,請在配置文件中添加配置
mysql> SET sql_mode =‘STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION‘; Query OK, 0 rows affected (0.00 sec)
配置文件中添加配置
sql_mode =‘STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION‘
