Description

                PreparedStatement preparedState = conn.prepareStatement(correctedSql);
                processStatementAttr(preparedState, sqlRequest);

                for (int i = 0; i < ((PrepareSqlRequest) sqlRequest).getParams().length; i++) {
                    setParam(preparedState, i + 1, ((PrepareSqlRequest) sqlRequest).getParams()[i]);
                }

                resultSet = preparedState.executeQuery();

preparedState should be closed upon returning from the method.
