मेरे पास एक विभाजन दृश्य है जिसमें नीचे सम्मिलित ट्रिगर (गरीब आदमी विभाजन) है। जब मैं एक DELETE करता हूं, तो मुझे नीचे क्वेरी योजना मिलती है:
delete from factproductprice where pricedate = '20170725'
दृश्य पर ट्रिगर:
ALTER TRIGGER [dbo].[factProductPriceDelete] ON [dbo].[FactProductPrice]
INSTEAD OF DELETE AS
BEGIN
IF @@ROWCOUNT = 0 RETURN;
DECLARE @PriceDate DATE
SELECT @PriceDate = CAST(PriceDate AS DATE) FROM DELETED
IF @PriceDate BETWEEN '20140101' AND '20141231'
BEGIN
DELETE FROM dbo.FactProductPrice2014
WHERE ProductId IN (SELECT ProductId FROM DELETED) AND SalesPriceSchemeId IN (SELECT SalesPriceSchemeId FROM DELETED) AND PriceDate IN (SELECT PriceDate FROM DELETED)
END
IF @PriceDate BETWEEN '20150101' AND '20151231'
BEGIN
DELETE FROM dbo.FactProductPrice2015
WHERE ProductId IN (SELECT ProductId FROM DELETED) AND SalesPriceSchemeId IN (SELECT SalesPriceSchemeId FROM DELETED) AND PriceDate IN (SELECT PriceDate FROM DELETED)
END
IF @PriceDate BETWEEN '20160101' AND '20161231'
