How to Use

• Almost setter made by fluent interface.
  • It returns the instance itself.
    • It means that you can chain methods.
    • For example, tbl.where("b", EQUAL, 10).selectAll().
• You can use the Tbl.from() method to convert the List<Map<String, Object>> to Tbl.
• You can use the toRowMapList() method to convert the Tbl to List<Map<String, Object>>.
• This is an example of how to use the Tbl class.
  • test code

public List<OrderDetailView> findOrderedDetailViewList(String userId) throws IllegalAccessException {
        List<Order> orderList = orderJpaRepository.findByUserId(userId);
        List<PgView> pgViewList = pgClient.findPgViewListByUserId(userId);
        List<WmsView> wmsViewList = wmsClient.findWmsViewListByUserId(userId);

        Tbl orderTbl = Tbl.from(orderList);
        Tbl pgTbl = Tbl.from(pgViewList);
        Tbl wmsTbl = Tbl.from(wmsViewList);
        Tbl result = orderTbl.innerJoin(pgTbl)
                .on("id", "orderId")
                .selectAll()
                .toTbl()
                .innerJoin(wmsTbl)
                .on("id", "orderId")
                .selectAll()
                .toTbl();
        List<Map<String, Object>> mapList = result.toRowMapList();
        return mapList.stream()
                .map(OrderDetailView::fromRowMap)
                .toList();
    }
