Generates the maximum value of rows in each group that meet a specific condition. Inputs can be Integer, Decimal, or Datetime. |
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 maximum value of rows without conditionals, use the MAX function. See MAX Function.
maxif(testScores, testCount >= 3) |
Output: Returns the maximum of the testScores column when the testCount is greater than or equal to 3.
maxif(col_ref, test_expression) [group:group_col_ref] [limit:limit_count] |
| Argument | Required? | Data Type | Description |
|---|---|---|---|
| col_ref | Y | string | Reference to the column you wish to evaluate. |
| test_expression | Y | string | Expression 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 Integer, Decimal, or Datetime values.
NOTE: If the input is in Datetime type, the output is in unixtime format. You can wrap these outputs in the DATEFORMAT function to generate the results in the appropriate Datetime format. See DATEFORMAT Function. |
| Required? | Data Type | Example Value |
|---|---|---|
| Yes | String that corresponds to the name of the column | myValues |
This parameter contains the expression to evaluate. This expression must resolve to a Boolean (true or false) value.
| Required? | Data Type | Example Value |
