MySQL 5.7.5后实现了对功能依赖的检测。默认启用了only_full_group_by 的SQL模式，会抛出：Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'userinfo. 在session和global 的sql_mode的值都为： 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 执行select @@sql_mode;查询；执行以下两个命令去掉：ONLY_FULL_GROUP_BY就好； set global sql_mode = 'STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'; set session sql_mode= 'STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'; (责任编辑：IT) |
