Question

我有一个非常庞大的SP，我有一个交易。我正在SP中运行算法，如果算法不成功，则回滚事务。

即使事务被回滚，我也需要记录一些数据，但是当事务回滚时，它也会回滚日志。这是正常行为，但我需要从回滚中排除该日志插入语句，以便仍然记录事务。

我有一个名为#MissingAllocationLines的临时表，我将日志插入该表。然后，如果它回滚，我需要将#MissingAllocationLines中的所有行插入真实表DLWMS_ALLOCATIONMISSINGLOG

这可能吗？我的示例代码在

下面

create table #MissingAllocationLines
(ALLOCATIONJOBID BIGINT,
ORDERID BIGINT,
ORDERDETAILID BIGINT,
ITEMID BIGINT,
STOCKQUANTITY BIGINT,   
ORDERQUANTITY BIGINT)


BEGIN TRANSACTION

WHILE(.....)
BEGIN
    INSERT INTO #MissingAllocationLines (ALLOCATIONJOBID,ORDERID,ORDERDETAILID,ITEMID,STOCKQUANTITY,ORDERQUANTITY)
    VALUES (@ALLOCATIONJOBID,@OrderID,@OrderDetailID,@ItemID,ISNULL(@StockFreeQuantity, 0),ISNULL(@RemainingQuantity,0))
    ...
    ...
    ...
END

IF(@DONE=1)
BEGIN
    COMMIT TRANSACTION
END
ELSE
BEGIN
    ROLLBACK TRANSCATION

    INSERT INTO DLWMS_ALLOCATIONMISSINGLOG (ALLOCATIONJOBID,ORDERID,ORDERDETAILID,ITEMID,STOCKQUANTITY,ORDERQUANTITY)
    SELECT ALLOCATIONJOBID,ORDERID,ORDERDETAILID,ITEMID,STOCKQUANTITY,ORDERQUANTITY
    FROM #MissingAllocationLines
END

Answer 1

尝试使用表变量而不是临时表。表变量不参与事务。

Answer 2

在catch块中，在回滚事务之前，请执行以下操作...

 DECLARE @TABLE AS TABLE
    (COL1 INT,
     COL2 INT
    ...
     )
     INSERT INTO @TABLE 
     SELECT * FROM #TEMP TABLE

    ROLLBACK TRANSCATION

    INSERT INTO DLWMS_ALLOCATIONMISSINGLOG 
     select * from @table

查看SAVE TRANSACTION命令。

您可以将'remote proc transaction promotion'用作false并使用该链接服务器进行日志记录到本地服务器：代码如下

begin tran outertran
insert into t values (1)
begin tran innertran
insert into localserver.tempdb.#log values (1)
commit tran innertran
IF (@Done) 
begin 
     commit tran outertran
end
else begin
rollback tran outertran
end 

select * from #log

EXEC sp_addlinkedserver @server = N'localserver',@srvproduct = N'',@provider = N'SQLNCLI', @datasrc = @@SERVERNAME
EXEC sp_serveroption localserver,N'remote proc transaction promotion','FALSE'
EXEC sp_serveroption localserver,N'RPC OUT','TRUE' -- Enable RPC to the given server
