The expression can use inline functions. For example, to calculate the minimum over an average of a multivalued column, use MV_AVG to first average the multiple values per row, and use the result with the MIN function
FROM employees
| STATS min_avg_salary_change = MIN(MV_AVG(salary_change))
| min_avg_salary_change:double |
|---|
| -8.46 |
MIN can also operate on exponential_histogram fields, returning the minimum of the values which were used to construct the histograms.
