在Power BI DAX中使用IF函数是一种条件语句,用于根据特定条件返回不同的结果。IF函数的语法如下: IF(条件, 结果1, 结果2) 其中,条件是一个逻辑表达式,如果为真,则返回结果1;如果为假,则返回结果2。 IF函数在Power BI中的应用场景非常广泛,可以用于数据转换、计算衍生指标、创建动态报表等。以下是一些常见的应用...
your weekly or monthly data would use a single date to represent the time period (e.g., end-of-week date, end-of-month date), and you would then join this date to
CALCULATE() alters the filtering behaviour of a visual by applying zero, one, or more filters prior to evaluating the expression. CALCULATE() then “reruns” the built-in filter propagation engine in Power BI—the one that makes the filters automatically propagate from the lookup tables and flow...
You can create variables within an expression by usingVAR. VAR is technically not a function, it's a keyword to store the result of an expression as a named variable. That variable can then be passed as an argument to other measure expressions. For example: ...

expressionAny DAX expression that returns a table or scalar value. The expression can use any of the defined entities. If there is a need to convert a scalar expression into a table expression, wrap the expression inside a table constructor with curly braces{}, or use theROW()function to ...
If the expression has a digit in the position where the 0 appears in the format string, display it; otherwise, display a zero in that position.If the number has fewer digits than there are zeros (on either side of the decimal) in the format expression, display leading or trailing zeros....
If we consider this expression:FILTER的第一个参数很重要,再举一个列子如下所示: ColorGreen = CALCULATE ( COUNTROWS ( 'Demo' ), FILTER ( 'Demo', 'Demo'[Color] = "Green" ) ) We pass the whole Demo table to the FILTER condition, which results a filter of the current context with all ...
DAX formulas are very similar to Excel formulas. To create one, you type an equal sign, followed by a function name or expression, and any required values or arguments. Like Excel, DAX provides a variety of functions that you can use to work with strings, perform calculatio...
