|
|
```esql
|

FROM employees
|
||
|
|
| STATS MEDIAN(salary), PERCENTILE(salary, 50)
|
||
|
|
```

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
|

|
|
|
||
|
|
```esql
|
||
|
|
FROM employees
|
||
|
|
| STATS median_max_salary_change = MEDIAN(MV_MAX(salary_change))
|
||
|
|
```
|
||
|
|
|
||
|
|
| median_max_salary_change:double |

`MEDIAN` is also [non-deterministic](https://en.wikipedia.org/wiki/Nondeterministic_algorithm). This means you can get slightly different results using the same data.
