MEDIAN
Description

This function calculates the median per group. Median can be applied to INT, FLOAT or DATE columns.

The median is the middle element of a group. If the group has an even number of elements, the upper value of the two middle values is taken as the median.

Syntax
 MEDIAN ( table.column )
NULL handling

NULL values are ignored, meaning that they do not influence the result. If all values of a group are NULL, the result for this group is also NULL.
