Sql 更新查询不会触发所有记录的更新触发器

Question

我从 table1 触发器调用了更新查询，当该查询运行时，它成功更新了其他 table2，但 table2 的更新触发器仅触发了 1 次，这意味着不是针对从更新查询更新的每条记录

我使用的是 SQL Server 2008 Express 版本-

请指点我哪里错了

Answer 1

终于得到了答案：/，触发器触发一次以执行单个查询。批量或批量更新/插入/删除不会唤醒每一行的触发器 :(，我非常感谢 Markov 先生和 David Dubois 先生，他们有兴趣帮助我:) 谢谢亲爱的，

ALTER TRIGGER [dbo].[tbl_Inv_PurchaseNoteDetailUpdate] 
   ON  [dbo].[tbl_Inv_PurchaseNoteDetail] 
   AFTER Update
AS 
BEGIN
    SET NOCOUNT ON;

Declare @RefNo as varchar(15) Declare @rate as float 
Declare @NewNetValue as float Declare @OldNetValue as float

select
@RefNo=ReferenceNo,
@rate=Rate
from inserted 


select 
@NewNetValue=isnull(i.NetAmount,0), @OldNetValue=isnull(d.NetAmount,0)
from inserted i inner join deleted d on i.id = d.id  

 --if amount changes then rate should be updated to another table 
if  @NewNetValue<>@OldNetValue 
begin
    -- using cursor work fine, update trigger of table[tbl_Inv_Ledger] is fired for every record
    Declare @Inv_LedgerID as numeric
    DECLARE  PurchaseNoteDetail_Cursor  CURSOR FOR
    Select ID from dbo.tbl_Inv_Ledger where ReferenceNo=@ReferenceNo 
    and FK_tbl_Inv_PurchaseNoteDetail_ID is null 
    and FK_tbl_Inv_PurchaseReturnNoteDetail_ID is null -- also check purchase return entry should not be distrubed

    OPEN  PurchaseNoteDetail_Cursor
    FETCH NEXT FROM  PurchaseNoteDetail_Cursor INTO @Inv_LedgerID
    WHILE @@FETCH_STATUS = 0
    BEGIN

    update dbo.tbl_Inv_Ledger
    set Rate=@Rate
    where ID=@Inv_LedgerID

    FETCH NEXT FROM  PurchaseNoteDetail_Cursor INTO @Inv_LedgerID
    END
    CLOSE   PurchaseNoteDetail_Cursor
    DEALLOCATE   PurchaseNoteDetail_Cursor 
end

这是触发并使用更新查询更新另一个表的触发器，但没有为除已更新的第二个表的第一条记录之外的所有记录触发更新触发器。

    ALTER TRIGGER [dbo].[tbl_Inv_PurchaseNoteDetailUpdate] 
       ON  [dbo].[tbl_Inv_PurchaseNoteDetail] 
       AFTER Update
    AS 
    BEGIN
        SET NOCOUNT ON;

    Declare @RefNo as varchar(15) Declare @rate as float 
    Declare @NewNetValue as float Declare @OldNetValue as float

    select
    @RefNo=ReferenceNo,
    @rate=Rate
    from inserted 


    select 
    @NewNetValue=isnull(i.NetAmount,0), @OldNetValue=isnull(d.NetAmount,0)
    from inserted i inner join deleted d on i.id = d.id  

     --if amount changes then rate should be updated to another table 
    if  @NewNetValue<>@OldNetValue 
    begin

        ---this will update new rate in table[tbl_Inv_Ledger] 
        --but didnot fire update trigger of table[tbl_Inv_Ledger] for all record which was updated
    update dbo.tbl_Inv_Ledger
    set Rate=Rate
    where ReferenceNo=@RefNo
    ---update trigger of table[tbl_Inv_Ledger] is fired only for first record
    end     

end
