JDBC Statement implementation of Phoenix. Currently only the following methods are supported: - {@link #executeQuery(String)}- {@link #executeUpdate(String)}- {@link #execute(String)}- {@link #getResultSet()}- {@link #getUpdateCount()}- {@link #close()}The Statement only supports the following options: - ResultSet.FETCH_FORWARD - ResultSet.TYPE_FORWARD_ONLY - ResultSet.CLOSE_CURSORS_AT_COMMIT @author jtaylor @since 0.1
