## Using connections

When you need to execute sequential queries (without a transaction), you can create a new connection or borrow one from the pool:

Prepared queries can be created:

    var Tuple = require("vertx-sql-client-js/tuple");
    connection.prepare("SELECT * FROM users WHERE first_name LIKE ?", function (ar1, ar1_err) {
      if (ar1_err == null) {
        var prepared = ar1;
        prepared.query().execute(Tuple.of("julien"), function (ar2, ar2_err) {
          if (ar2_err == null) {
            // All rows
            var rows = ar2;
          }
        });
      }
    });
