IF DAX Function (Logical)

Sprawdza, czy jest spełniony warunek i zwraca jedną wartość, jeśli jest spełniony, a inną wartość, gdy nie jest spełniony.

Syntax

IF ( <LogicalTest>, <ResultIfTrue> [, <ResultIfFalse>] )
Parameter Attributes Description
LogicalTest

Dowolna wartość lub wyrażenie, które może przyjąć wartość PRAWDA lub FAŁSZ.

ResultIfTrue

The value that is returned if the logical test is TRUE.

ResultIfFalse Optional

The value that is returned if the logical test is FALSE.
If omitted, a BLANK is returned.

Return values

Scalar A single value of any type.

Either ResultIfTrue or ResultIfFalse expression result, depending on LogicalTest.

Remarks

Using IF can generate multiple branches of code execution that could result in slower performance at query time.
Then IF can return BLANK as one of the results, there are cases where using DIVIDE to obtain the same result could produce a faster query plan.
The following code returns BLANK if LogicalTest is false.

IF ( <LogicalTest>, <ResultIfTrue> )

The previous code is semantically equivalent to the following expression:

DIVIDE ( <ResultIfTrue>, <LogicalTest> )
