1. 3. 单独聚合查询: aggregate # 语法: aggregate(别名=聚合函数('字段')) # 规则: 1.可以同时对多个字段进行聚合处理:aggregate(别名1=聚合函数1('字段1'), ..., 别名n=聚合函数n('字段n')) 3.是QuerySet对象方法 2.方法返回值返回值为dict类型 # 案例:所有书中最贵的书的价格 Book.objects.all...
PolarDB解决问题的思路是对该SQL做查询变换, 把IN-List转变成一张物化表,加入join list,具体变换过程如下: Step 1:转成in子查询,上述SQL改写为 select...fromlineitemwherel_partkeyin(...)===>select...fromlineitemwherel_partkeyin(selectdt._col_1from(values(9628136),(19958441),...)dt) Step 2:...
which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_...

1.查看.sql_mode配置 select@@global.sql_mode; 2.查看返回信息是否包含ONLY_FULL_GROUP_BY ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION; 3.去掉ONLY_FULL_GROUP_BY ,其他参数不变,执行即可 SETGLOBAL sql_mode=‘STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION’; ...
only_full_group_by这个 sql_mode 的唯一要求,就是所有的select 字段必须在 group by 字段中,否则必须出现在 SQL Aggregate 函数中,反过来却是非必须的 假设我们有下面一张表employee CREATETABLEIFNOTEXISTS`employee`(`id`INTUNSIGNEDAUTO_INCREMENT,`name`VARCHAR(64)NOTNULL,`depart`VARCHAR(128)NOTNULL,`depart...
