因为DAX知道销售表和客户表之间的现有关系,所以它会自动随着模型进行筛选。最后,SUMMARIZE函数需要由"客户表" [客户名字]执行分组,整个公式没使用任何关键字。 DAX是一种函数式的语言 SQL是一种声明性语言。您可以通过使用SELECT语句声明从数据集中检索出所需内容,而不必担心引擎该如何检索信息。另一方面,DAX是一种函数...
The query returned varies depending on the data type of the column, showing different statistics for numeric, text, and date columns. Measures Evaluate creates a query to show the result of the measure. SUMMARIZECOLUMNS() is used so you can add in any group by columns to show the measure ...
对比没有allselectd的情况下的筛选 ALLNOBLANKROW函数:从关系的父表中,返回除空白行之外的所有行,或某一列中除空白行之外的所有非重复值,并且忽略可能存在所有上下文的筛选器。 语法:ALLNOBLANKROW(<table>|<column>) 1. 若选table要删除其所有上下文筛选器的表,列同理,创建一个度量值 ...

If we used theAccountKeycolumn to limit the visibility, we would end up limiting the visibility to only one row and the user would not see the children nodes. By leveraging the path column, we can easily select multiple rows by including all the nodes that can be reached when traversing ...
