Window.RowNumber = ROWNUMBER( ALLSELECTED( 'DataTable'[Item] ) , ORDERBY( CALCULATE( SUM( 'DataTable'[Value] ) ) ) ) 效果如下: 可以看出,在大小一样的情况下,会按元素的名字优先排序得到结果。 总结 对于窗口函数来说,其本质是形成一个窗口区域,ROWNUMBER 用于唯一化定位当前元素在窗口区域中的位置。

Row_Number函数是一种在关系型数据库中常用的窗口函数,用于为结果集中的每一行分配一个唯一的序号。它可以根据指定的排序规则对结果集进行排序,并为每一行分配一个连续的整数值。 Row_Number函数的语法如下: 代码语言:txt 复制 ROW_NUMBER() OVER (ORDER BY column1, column2, ...) 其中,ORDER BY子句用于指定...

表示属于表的所有行的集合。 请注意,与区域或列不同,如果新行或列被添加到它们之前,区域或列将进行调整, TableRow 对象表示表行的物理位置,而不是数据。 也就是说,如果对数据进行排序或添加新行,则表行将继续指向创建它的索引。
