Improving Min/Max Aggregation over Spatial Objects 来自 Semantic Scholar 喜欢 0 阅读量: 28 作者: VJ Tsotras 摘要: We examine the problem of computing MIN/MAX aggregates over a collection of spatial objects. Each spatial object is associated with a weight (value), for example, the average ...
直接看例子,先查询出所有 Sub Category 下的 Reseller Sales Amount。 然后使用 MAX 函数查询出 Sub Category 下最大的 Reseller Sales Amount。在这里查询的范围即 SET 集合是 Sub Category 的所有成员,比较大小的依据是 Reseller Sales Amount,即在 SET 集合中查找 Reseller Sales Amount 的最大值。 比较每个 Su...
聚合函数aggregation function又称为组函数。认情况下 聚合函数会对当前所在表当做一个组进行统计。 2.聚合函数的特点 1.每个组函数接收一个参数(字段名或者表达式)统计结果中默认忽略字段为NULL的记录 2.要想列值为NULL的行也参与组函数的计算,必须使用IFNULL函数对NULL值做转换。
