Returns the most common Datetime value of rows in each group that meet a specific condition. Set of values must valid Datetime values.

NOTE: When added to a transformation, this function is applied to the current sample. If you change your sample or run the job, the computed values for this function are updated. Transformations that change the number of rows in subsequent recipe steps do not affect the values computed for this step.

To calculate the most common Datetime value of rows without conditionals, use the MODEDATE function. See MODEDATE Function.

modedateif(incidentDate, serverFailure == 'true')

Output: Returns the most common date from the incidentDate column when the value in the serverFailure column is true.

modedateif(col_ref, test_expression) [group:group_col_ref] [limit:limit_count]

ArgumentRequired?Data TypeDescription
col_refYstringReference to the column you wish to evaluate. Values in the columns must be valid Date values.
test_expressionYstringExpression that is evaluated. Must resolve to true or false

For more information on the group and limit parameters, see Pivot Transform.


Name of the column whose values you wish to use in the calculation. Inputs must be Datetime values.

Required?Data TypeExample Value
YesString that corresponds to the name of the columnmyDates


This parameter contains the expression to evaluate. This expression must resolve to a Boolean (true or false) value.

Required?Data TypeExample Value
