<code>SELECT * FROM table
WHERE ANY(field > 10);</code>

If If there are any rows in table that have a field value greater than 10, this query will return all those rows.

Determine whether all rows meet the condition:

<code>SELECT * FROM table
WHERE NOT ANY(field < 10);</code>

If the field value of all rows in table is greater than or equals 10, this query will return all those rows. Otherwise, it returns an empty result set.
