Computes the average (mean) from all row values in a column. 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.
For a version of this function computed over a rolling window of rows, see ROLLINGAVERAGE Function.
