== Using connections

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

[source,groovy]

Prepared queries can be created:

[source,groovy]
----
connection.prepare("SELECT * FROM users WHERE first_name LIKE ?", { ar1 ->
  if (ar1.succeeded()) {
    def prepared = ar1.result()
    prepared.query().execute(Tuple.of("julien"), { ar2 ->
      if (ar2.succeeded()) {
        // All rows
        def rows = ar2.result()
      }
    })
  }
})
