合併語句和觸發器SQL Server 2012

Question

我有一個合併語句應該多次執行觸發器。

我首先想到我的觸發器沒有執行，但是通過一些研究，我發現觸發器每個語句只觸發一次（觸發器是一個語句）。

但是所有的帖子都是舊的，我認爲現在可能有一個簡單的方法來讓我的觸發器執行多次。

那麼有什麼我可以添加到我的觸發器或我的合併聲明，使我的觸發器這樣做？

感謝

TRIGGER

BEGIN

MERGE語句

Merge ZZ AS TARGET USING ZZTemp AS SOURCE 
ON (Target.Operation=Source.Operation AND Target.Ordre=Source.Ordre) 
WHEN MATCHED THEN 
UPDATE SET TARGET.DateTERA=SOURCE.DateTERA, TARGET.MatTERA=SOURCE.MatTERA, TARGET.MatTERC=SOURCE.MatTERC 
WHEN NOT MATCHED THEN      
INSERT(Operation,Ordre,ElementOTP,Article,DesignationOF,PosteTravail,ValeurTemps,DHT,Statut,StatutOF,TexteActivite,DateTERA,MatTERA,MatTERC,StatutMat)         
VALUES(SOURCE.Operation,SOURCE.Ordre,SOURCE.ElementOTP,SOURCE.Article,SOURCE.DesignationOF,SOURCE.PosteTravail,SOURCE.ValeurTemps,SOURCE.DHT, 
SOURCE.Statut,SOURCE.StatutOF,SOURCE.TexteActivite,SOURCE.DateTERA,SOURCE.MatTERA,SOURCE.MatTERC,SOURCE.StatutMat);

您的問題是，光標不正確的寫入處理的數據集。任何設置插入或刪除標量變量的值形式的觸發器都不正確，並且由於數據完整性的原因必須重寫。這個觸發器是越野車。期。沒有必要重寫它（以及其他使用相同技術的其他程序）。

您的觸發器中的代碼應該是這樣的：

INSERT INTO Log(NumeroOF,Matricule,IdAction,Date,EstAdmin) 
SELECT max(Id),l.Matricule,l.IdAction, 13,GETDATE(),1 
FROM Log l 
JOIN Inserted i ON l.NumeroOF = i.Ordre 
WHERE i.Statut LIKE '%CLOT%' OR i.Statut LIKE '%CLTT%' OR i.Statut LIKE '%CONF%' 
GROUP BY l.Matricule,l.IdAction 

INSERT INTO Log(NumeroOF,Matricule,IdAction,Date,EstAdmin) 
SELECT max(Id),l.Matricule,l.IdAction, 2,GETDATE(),1 
FROM Log l 
JOIN Inserted i ON l.NumeroOF = i.Ordre 
WHERE IdAction<=2 
WHERE i.Statut LIKE '%CLOT%' OR i.Statut LIKE '%CLTT%' OR i.Statut LIKE '%CONF%' 
GROUP BY l.Matricule,l.IdAction 

確保與單記錄和多個記錄插入到測試所有觸發器應該進行測試。一旦你確信觸發器是正確的，然後嘗試你的MERGE。
