How to use the alasql.Database function in alasql

//
// AlaSQL node.js sample
//

var alasql = require('alasql');

var db = new alasql.Database();

db.exec("CREATE TABLE test (one INT, two INT)");
db.tables.test.data = [   // You can mix SQL and JavaScript
    {one:3,two:4},
    {one:5,two:6},
];

var res = db.exec("SELECT * FROM test ORDER BY two DESC");

console.log(res);

let columns: string[] = [];
            let lines: string[][] = [];
            let i = 0;
            for ( let row of table.rows ) {
                if ( 0 === i ) {
                    columns = row.cells;
                } else {
                    lines.push( row.cells );
                }
                ++i;
            }
            */

var mybase = new alasql.Database('mybase');
