sql-server - 合并语句和触发器 SQL Server 2012

Question

我有一个合并语句应该多次执行触发器。

我首先以为我的触发器没有执行，但经过一些研究，我发现每个语句仅触发一次触发器(一个触发器就是一个语句)。

但是所有的帖子都是旧的，我认为现在可能有一种简单的方法可以让我的触发器多次执行。

那么我可以在触发器或合并语句中添加任何内容以使触发器执行此操作吗？

谢谢

您的问题是游标被错误地写入来处理数据集。任何将值形式插入或删除到标量变量的触发器都是不正确的，出于数据完整性的原因必须重写。这个触发器有问题。时期。无可避免的是，它必须被重写(以及使用相同技术的任何其他内容)。

触发器内的代码应该类似于:

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  

确保使用单记录和多记录插入进行测试，因为应测试所有触发器。一旦您确信触发器正确，就尝试合并。
