本文先让我们理解CALCULATE的基本工作原理。 原文 The CALCULATE function in DAX is the magic key for many calculations we can do in DAX. However, it is not pretty intuitive how it works and I spent a lot of time trying to understand how it can be used.DAX的CALCULATE函数是很多应用场合的关键...
When filter expressions are provided, the CALCULATE function modifies the filter context to evaluate the expression. For each filter expression, there are two possible standard outcomes when the filter expression is not wrapped in the KEEPFILTERS function: If the columns (or tables) aren't in the...
regardless it is a slicer, a report filter or a row/column selection), any reference for that column in one ormore filter parameters of the Calculate function replaces the existing context. Then, the filters specified inthe CALCULATE parameters are combined together ...
Related Functions Whereas the CALCULATE function requires as its first argument an expression that returns a single value, the CALCULATETABLE function takes a table of values. See Also Other Resources CALCULATETABLE Function (DAX) Filter Functions (DAX)...
In this blog, I’ll cover how the CALCULATE function works and why it’s a very significant DAX function in Power BI. I’ll show you some examples of its application through some of our tutorials on Enterprise DNA. CALCULATEis one of the most dynamic functions that can he...
CALCULATE(<expression>[, <filter1> [, <filter2> [, …]]]) 參數展開資料表 術語定義 expression 要評估的表達式。 filter1, filter2,… (選擇性)定義篩選條件或篩選修飾詞函式的布爾表達式或數據表表達式。做為第一個參數的表達式基本上與量值相同。篩選可以是:布爾...
Examples Simple Date The following formula returns the date July 8, 2009: DAX Years before 1899 If the value that you enter for theyearargument is between 0 (zero) and 1899 (inclusive), that value is added to 1900 to calculate the year. The following formula returns January 2, 1908: (...
= CALCULATE(SUM(InternetSales_USD[SalesAmount_USD]), DATESYTD(DateTime[DateKey])) 下列範例公式會建立一個量值,此量值會使用美國地區設定來計算因特網銷售的「會計年度執行總計」,以取得日期格式。DAX 複製 = CALCULATE( SUM(InternetSales_USD[SalesAmount_USD]), DATESYTD(DateTime[DateKey], "6-30" ) ...
because it can do everything a calculate column can do (in this case) but doesn't need to materialise a new column into the table. In Power BI, fewer columns is always better • You can materialise a FILTER() function by using the New Table option if you want to see how it works...
CALCULATE 与筛选器参数 CALCULATE 接受三种类型的筛选器: 表形式的值列表 在这种情况下,你将提供需要在新的筛选上下文中显示的值列表,筛选器可以是单列形式的表,也可以是具有多个列的表,就像将整张表作为筛选器一样,FILTER是其中最常用的函数之一。 布尔表达式 ...
