> A lot of users are interested in doing "arg_min" and "arg_max". Basically, return the value of some other columns when one column's value is the max value.
> The following is an example usage when this is done:
> {code}
> SELECT department, max(struct(salary, employee_name))
> FROM compensations;
> {code}
