Well, I would use streams and their on method which IMO resembles the functional approach...

Do you mean in JS or Java? Because in Java doing it the functional way is extremely complex according to stackoverflow.com/questions/322092...

Do you have a JS example that reads rows from a relational DB without using loops?

I meant JavaScript. An example could be Google Lovefield (haven't tried it though).

By looking at the Readme, it seems like this API returns an array of rows. Which obviously is not acceptable when dealing with huge result sets.

}).then(function(results) {
// The SELECT query's Promise will return array of rows selected.
// If there were no rows, the array will be empty.

results.forEach(function(row) {
// Use column name to directly dereference the columns from a row.
console.log(row['description'], 'before', row['deadline']);
});
});
