The expression can use inline functions. For example, to calculate the maximum over an average of a multivalued column, use `MV_AVG` to first average the multiple values per row, and use the result with the `MAX` function
|
||
|
|
|
||
|
|
```esql
|
||
|
|
FROM employees
|
||
|
|
| STATS max_avg_salary_change = MAX(MV_AVG(salary_change))
|
||
|
|
```
|
||
|
|
|
||
|
|
| max_avg_salary_change:double |
