咪卡四處看

service需先進行delect 再select新資料

service：

@Transactional(propagation = Propagation.REQUIRED, rollbackFor = Exception.class)
  public List<CreditCardInfoResponse> getCreditCardList(Long fridayUid) {
      //移除資料
      prodDao.deleteByProdId(prodId);
      prodDao.flush();
      
      //撈取資料
      List<prod> prodList = prodDao.findByProdId(ProdId);
  }

Dao

  public interface prodDao{
  
	public List<prod> findByProdId(Long prodId);
	
	@Modifying
	@Transactional
	@Query("delete from Prod where prodId = :prodId")
	public int deleteByIdFridayUidAndIsDefault(Long prodId);
  }

==>

如果表定Query，實際對資料庫操作

1.  delete from PROD  where PRODID=?

2.  select PRODID, PRODNAME from PROD  where PRODID=?

Dao

  public interface prodDao{
  
	public List<prod> findByProdId(Long prodId);
	
	public int deleteByIdFridayUidAndIsDefault(Long prodId);
  }

如果使用原定義，實際對資料庫操作

1.  select PRODID, PRODNAME from PROD  where PRODID=?   // 多一次select

2.  delete from PROD  where PRODID=?

3.  select PRODID, PRODNAME from PROD  where PRODID=?
