After Connecting, you can execute a SQL statement and retrieve the results.

SELECT Procedure

You can use the query method to execute the statement. It will split the query results into batches, and invoke a callback once for each batch. The rows are given to the callback as a list of objects, along with a flag indicating whether more rows are available.

db.open("...", (err) => {
    db.query("SELECT DocumentNumber, Revision FROM Orders WHERE VendorId = 'v1'", (err, rows, moreRows) => {
        for (var i = 0; i < rows.length; i++) {
            var row = rows[i];
            console.log("DocumentNumber = " + row["DocumentNumber"]);
            console.log("Revision = " + row["Revision"]);
        }

        if (!moreRows) {
            console.log("All rows have been processed");
        }
    });
});
