As you can see in the following table, the result of a comparison to an expression that evaluates to BLANK matches the first blank or false value found in the list. When you use SWITCH, the behavior is different, because it applies a different comparison logic that matches the BLANK value using the ISBLANK function internally. When you use nested IF functions, the order of comparisons to equivalent BLANK values is important, because only the first one matches the comparison. In this case, the measures containing an empty string generates an error during evaluation, because it cannot be converted to a valid value by the VALUE function. If you invert the two comparisons, now there are two values (zero and blank) that match the first condition of the two IF statements, and the second is never executed. Īll the three values (zero, empty string, and blank) match the first condition of the two IF statements, and the second IF is never executed. For example, consider the following expression and the result for different values of. The automatic conversion to zero or empty string of a blank value might have undesired side effects. IF ( ISBLANK ( BLANK () ), "true", "false" ) The next table shows a number of examples that illustrates how you obtain a positive match comparing a blank values with an empty string and a zero value. For this reason, comparing an expression to blank requires a specific function, ISBLANK, which returns true whenever its only argument is a blank expression. When you use BLANK in a comparison, the conversion to 0 or to an empty string results in a positive match with these values. You can replace the call to the BLANK function with any DAX expression returning a blank value, including a column reference. The following table shows what is the result of several expression containing a blank value. You can obtain a blank value in DAX calling the BLANK function. When you evaluate a DAX expression, a blank value is always converted to 0 or to an empty string, depending on the data type requested by the expression, unless it is evaluated in any term of a multiplication, in which case the blank value propagates in the multiplication result. If you are used to SQL, you might expect a propagation of the blank value in a DAX expression, but in reality the behavior is different. This is the value assigned to a column when the data source contains a NULL value. What is a blank value in DAXĪny column data type in DAX can have a blank value.
