问题描述
您可以使用表值参数存储触发器中插入/删除的值,并将其传递给proc。例如,如果您在proc中所需的全部是UNIQUEFileID's
:
CREATE TYPE FileIds AS TABLE
(
FileId INT
);
-- Create the proc to use the type as a TVP
CREATE PROC commonProc(@FileIds AS FileIds READONLY)
AS
BEGIN
UPDATE at
SET at.DateVersion = CURRENT_TIMESTAMP
FROM ATable at
JOIN @FileIds fi
ON at.FileID = fi.FileID;
END
然后从触发器中传递插入/删除的ID,例如:
CREATE TRIGGER MyTrigger ON SoMetable FOR INSERT
AS
BEGIN
DECLARE @FileIds FileIDs;
INSERT INTO @FileIds(FileID)
SELECT disTINCT FileID FROM INSERTED;
EXEC commonProc @FileIds;
END;
解决方法
我为几个表创建触发器。触发器具有相同的逻辑。我将要使用一个通用的存储过程。但是我不知道如何处理 插入 和 删除的 表。
例子:
SET @FiledId = (SELECT FiledId FROM inserted)
begin tran
update table with (serializable) set DateVersion = GETDATE()
where FiledId = @FiledId
if @@rowcount = 0
begin
insert table (FiledId) values (@FiledId)
end
commit tran
