也即,Grouping Sets语句的作用是指定几个grouping set作为Group By的分组规则,然后再将结果联合在一起。它的效果和,先分别对这些 grouping set 进行Group By分组之后,再通过 Union All 将结果联合起来,是一样的。 比如,对于dealer表,Group By Grouping Sets ((city, car_model), (city), (car_model), ())...

当您在执行 SQL 查询时,如果在 SELECT 子句中包含了非聚合函数的字段,而又没有在 GROUP BY 子句中指定该字段,那么就会抛出 "不在聚合函数或group by子句" 的异常。这是因为在执行 GROUP BY 查询时,数据库需要知道如何对每个分组中的非聚合字段进行处理,以便正确地返回结果集。 为了解决这个问题,您可以...
