There's also the CALCULATETABLE function. It performs exactly the same functionality, except it modifies the filter context applied to an expression that returns a table object.SyntaxDAX კოპირება CALCULATE(<expression>[, <filter1> [, <filter2> [, …]]]) Parameters...
A Boolean expression used as a filter parameter in a CALCULATE function corresponds to an equivalent FILTER expression that operates on all the values of a column (for this reason, you can only a single column can be used in a Boolean expression that is used as a table filter expression):C...
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。然而,它的工作原理远没有看上去那么简单,需要...

1- SUM DAX function SUM函数是一类聚合函数(aggregation function),用于计算一列中的所有数字之和(calculates the sum of all numbers in a column)。因此语法中引用字段列名称——这也是SUM函数的唯一变量(SUM support only single argument.)。 语法: SUM(<Column>) 这里介绍一个案例。 1.1 创建一个SUM函...
CALCULATE is the most powerful and complex function in DAX. In this article, we provide an introduction to CALCULATE, its behavior, and how to use it. CALCU
CALCULATE是DAX语言最重要的函数,之所以说它重要是因为它能改变可视化对象的初始筛选。(什么是初始筛选我们在之前章节有介绍)。 注:实际上还有一些其它函数能改变可视化对象的初始筛选,像CALCULATETABLE,CALCULATETABLE主要在DAX查询里使用,超出了本书介绍的范畴。
CALCULATE 和 CALCULATETABLE 是 DAX 中惟二可以修改筛选上下文的函数。实际上,CALCULATE 创建了一个新的筛选上下文,然后在新的上下文中计值表达式。因为新上下文的源自现有上下文,所以我们可以说它修改了计值上下文。
CALCULATE is the most important function in DAX. Quite a sweeping statement you might think but as soon as you get to grips with CALCULATE, you'll quickly realize that there won't be many expressions you author in DAX where this function won't be required, even though you might think we...
If the data has been filtered, the CALCULATE function changes the context in which the data is filtered, and evaluates the expression in the new context that you specify. For each column used in a filter argument, any existing filters on that column are removed, and the filter used in the...
