## Using connections

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

    Code not translatable

Prepared queries can be created:

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

Note | prepared query caching depends on the `setCachePreparedStatements` and does not depend on whether you are creating prepared queries or use `direct prepared queries`
