    All Methods Instance Methods Abstract Methods
    Modifier and Type | Method and Description
    --- | ---
    `Future<Void>` | `close()` Like `close(Handler)` but returns a `Future` of the asynchronous result
    `void` | `close(Handler<AsyncResult<Void>> handler)` Close the client and release the associated resources.
    `PreparedQuery<RowSet<Row>>` | `preparedQuery(String sql)` Create a prepared query, one of the `PreparedQuery.execute(io.vertx.sqlclient.Tuple, io.vertx.core.Handler<io.vertx.core.AsyncResult<T>>)` or `PreparedQuery.executeBatch(java.util.List<io.vertx.sqlclient.Tuple>, io.vertx.core.Handler<io.vertx.core.AsyncResult<T>>)` methods must be called to execute the query.
    `Query<RowSet<Row>>` | `query(String sql)` Create a query, the `Query.execute(io.vertx.core.Handler<io.vertx.core.AsyncResult<T>>)` method must be called to execute the query.

- - ### Method Detail

    - #### query

          Query<RowSet<Row>> query(String sql)

      Create a query, the `Query.execute(io.vertx.core.Handler<io.vertx.core.AsyncResult<T>>)` method must be called to execute the query.
      Returns:
        the query

    - #### preparedQuery

          PreparedQuery<RowSet<Row>> preparedQuery(String sql)

      Create a prepared query, one of the `PreparedQuery.execute(io.vertx.sqlclient.Tuple, io.vertx.core.Handler<io.vertx.core.AsyncResult<T>>)` or `PreparedQuery.executeBatch(java.util.List<io.vertx.sqlclient.Tuple>, io.vertx.core.Handler<io.vertx.core.AsyncResult<T>>)` methods must be called to execute the query.
      Returns:
        the prepared query

    - #### close

          void close(Handler<AsyncResult<Void>> handler)

      Close the client and release the associated resources.
      Parameters:
        `handler` - the completion handler

    - #### close

          Future<Void> close()

      Like `close(Handler)` but returns a `Future` of the asynchronous result
