SQL syntax term for 'WHERE (col1, col2) < (val1, val2)'

Question

As my question states, I would like to know what we call types of queries with that type of condition in the WHERE clause, i.e.:

SELECT * FROM m         


        

Answer 1

WHERE (col1, col2) < (val1, val2)

Above syntax is called Row Value Constructor/tuple syntax/Row Subquery.

From doc

ANSI SQL row value constructor syntax, sometimes referred to AS tuple syntax, even though the underlying database may not support that notion. Here, we are generally referring to multi-valued comparisons, typically associated with components

Alternatively it can be called Row Subqueries
