을 내가 예를 들어 어떤 값을 실행하려고 할 때 영향을 받고 실제로 마지막 값은 내 테이블에만 들어갑니다. 왜 그런가?

Answer 1

기본적으로,이 문으로, 동시에 둘 이상의 값을 물을 수 없습니다 당신의 변수 가입일 :

SELECT @OfferId = a.OfferId 
     ,@CountryId = a.CountryId 
     ,@VatRateId = a.VatRateId 
     ,@SalePrice = a.SalePrice 
     ,@SaleFromDate = a.SaleFromDate 
     ,@SaleToDate = a.SaleToDate 
     ,@DefaultPrice = a.DefaultPrice 
FROM @OfferPriceTVP a; 

당신이 당신의 입력 테이블의 한 레코드를 보유하고 있습니다.

입력 된 테이블을 OfferPrice 테이블과 병합하려고합니다. 따라서 MERGE 문을 사용하는 것이 좋습니다. 여기

MERGE OfferPrice AS TARGET 
USING (SELECT VatRateId 
      ,CASE WHEN Price IS NULL AND SalePrice IS NOT NULL AND GETUTCDATE() >= SaleFromDate AND GETUTCDATE() < SaleFromDate THEN SalePrice ELSE DefaultPrice END AS Price 
      -- And so on and so forth 
     FROM @OfferPriceTVP) AS SOURCE 
    ON TARGET.OfferId = SOURCE.OfferId 
WHEN MATCHED THEN 
    UPDATE SET VatRateId = SOURCE.VatRateId 
       ,Price  = SOURCE.Price 
       -- And so on and so forth 
WHEN NOT MATCHED THEN 
    INSERT (OfferId, CountryId) -- And so on and so forth 
    VALUES (SOURCE.OfferId, SOURCE.CountryId) -- And so on and so forth
