Fetch Function

The INTO helper uses a fetch function to get the row from a resulting query. The definition of the Fetch Function is described below.

var fetch = (count,rows,stmt) => 
(count && rows.next() && Array.apply(null,Array(stmt.getColumnCount())).map((_,i)
=> rows.getColumnValue(i + 1))) || [];

Some parts of the output code are omitted for clarity reasons.
