IF.EAGER

  • Article

Applies to: Calculated column Calculated table Measure Visual calculation

Checks a condition, and returns one value when TRUE, otherwise it returns a second value. It uses an eager execution plan which always executes the branch expressions regardless of the condition expression.

Syntax

IF.EAGER(<logical_test>, <value_if_true>[, <value_if_false>])

Parameters

Term Definition
logical_test Any value or expression that can be evaluated to TRUE or FALSE.
value_if_true The value that's returned if the logical test is TRUE.
value_if_false (Optional) The value that's returned if the logical test is FALSE. If omitted, BLANK is returned.

Return value

Either value_if_true, value_if_false, or BLANK.

Remarks

  • The IF.EAGER function can return a variant data type if value_if_true and value_if_false are of different data types, but the function attempts to return a single data type if both value_if_true and value_if_false are of numeric data types. In the latter case, the IF.EAGER function will implicitly convert data types to accommodate both values.

    For example, the formula IF.EAGER(<condition>, TRUE(), 0) returns TRUE or 0, but the formula IF.EAGER(<condition>, 1.0, 0) returns only decimal values even though value_if_false is of the whole number data type. To learn more about implicit data type conversion, see Data types.

  • IF.EAGER has the same functional behavior as the IF function, but performance may differ due to differences in execution plans. IF.EAGER(<logical_test>, <value_if_true>, <value_if_false>) has the same execution plan as the following DAX expression:

    
VAR _value_if_true = <value_if_true>
VAR _value_if_false = <value_if_false>
RETURN
IF (<logical_test>, _value_if_true, _value_if_false)

    Note: The two branch expressions are evaluated regardless of the condition expression.
