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.

pivot value:MAX(myRating) group:postal_code limit:1

Output: Generates a two-column table containing the unique values from the postal_code column and the maximum value of the myRating column for the postal_code value. The limit parameter defines the maximum number of output columns.
