SQL Server触发器触发但结果奇怪

Question

我在更新时设置了一个触发器。

如果我更新10行，第一个IF块将插入10行到changelog的 但是接下来的IF语句将只更新一行...不是10

第一个IF语句IF @attribute <> 'totalDescriptionLong'必火的10倍，正如我所料。

下一个IF语句IF @attribute = 'publishingStatus' 似乎只火一次......即使我更新10点或更多的行有资格获得这个...！

我不明白为什么代码的一部分在其他

ALTER TRIGGER [dbo].[AttributeUpdate]

    FROM inserted i 

    SELECT @nOldValue = d.Active FROM deleted d

的另一种方式，我认为这应该是八九不离十的作用。我对插入相当有信心，但更新可能需要稍微调整。当然，我大部分时间都在猜测，因为我没有桌子结构，也不能100％确定你要做什么。这应该是非常接近，但。

insert [DemandwareDataHub].[dbo].[ChangeLog] 
(
    ReferenceRecid 
    , EntityTypeID 
    , ActionType 
    , LogEntryDateTime 
    , PimChangeDateTime 
    , Processed 
) 
select i.RECID 
    , 1 
    , case when i.Active <> d.Active then 1 else 2 end 
    , getdate() 
    , i.TIMESTAMP 
    , 0 
from inserted i 
join deleted d on d.RECID = i.RECID --or whatever the primary key column(s) are 


UPDATE RETAILEXPORTOUTPUTEXTHUBDWATTRIBUTE 
set ATTRIBUTEVALUE = case when re.PRICELOCKED = 1 then 'proofed' else 'proofedPriceNotLocked' end 
from inserted i 
join SyncPimPriceBooks b on b.SiteID = i.SITE 
join RETAILEXPORTOUTPUTEXTDWPRICELOCKED re on re.ACCOUNTRELATION = b.CountryID AND re.PRODUCT = i.PRODUCT 
where re.ATTRIBUTE = 'publishingStatus'
