ANY

Aggregate function.

The ANY() function selects the first encountered (non-NULL) value, unless all rows have NULL values in that column. The query can be executed in any order and even in a different order each time, so the result of this function is indeterminate. To get a determinate result, you can use the ‘min’ or ‘max’ function instead of ‘any’.
