Computes the maximum value found in all row values in a column. Input column are permitted to be of Integer or Decimal. |
- When used in a
pivot
transform, the function is computed for each instance of the value specified in the group
parameter. See Pivot Transform. - If a row contains a missing or null value, it is not factored into the calculation.
- If no numeric values are found in the source column, the function returns a null value.
For a version of this function computed over a rolling window of rows, see ROLLINGMAX Function.
