Computes the approximate median from all row values in a column or group. Input column can be of Integer or Decimal.

  • If a row contains a missing or null value, it is not factored into the calculation. If the entire column contains no values, the function returns a null value.
  • When used in a pivot transform, the function is computed for each instance of the value specified in the group parameter. See Pivot Transform.
  • The approximate percentile functions utilize a different algorithm for efficiently estimating quantiles for streaming and distributed processing, depending on the running environment where the function is computed. 

    Tip

    Tip: Approximation functions are suitable for larger datasets. As the number of rows increases, accuracy and calculation performance improves for these functions.
