MEDIAN [esql-median]
Syntax
:::{image} ../../../../../images/median.svg :alt: Embedded :class: text-center :::
Parameters
true Description
The value that is greater than half of all values and less than half of all values, also known as the 50% PERCENTILE.
::::{note}
Like PERCENTILE, MEDIAN is usually approximate.
::::
Supported types
| number | result |
|---|---|
| double | double |
| integer | double |
| long | double |
Examples
FROM employees
| STATS MEDIAN(salary), PERCENTILE(salary, 50)
| MEDIAN(salary):double | PERCENTILE(salary, 50):double |
|---|---|
| 47003 | 47003 |
The expression can use inline functions. For example, to calculate the median of the maximum values of a multivalued column, first use MV_MAX to get the maximum value per row, and use the result with the MEDIAN function
FROM employees
| STATS median_max_salary_change = MEDIAN(MV_MAX(salary_change))
| median_max_salary_change:double |
|---|
| 7.69 |
::::{warning}
MEDIAN is also non-deterministic. This means you can get slightly different results using the same data.
