以下存储过程执行不佳。我想将其更改为合并声明。我该怎么做？我以前没有使用过 Merge 语句。请帮忙

IF  EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[pa_CPE_TUA_RD]') AND type in (N'P', N'PC'))
DROP PROCEDURE [dbo].[pa_CPE_TUA_RD]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
IF NOT EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[pa_CPE_TUA_RD]') AND type in (N'P', N'PC'))
BEGIN
CREATE PROCEDURE [dbo].[pa_CPE_TUA_RD]  
AS       
  -- This procedure moves RewardDistribution records from UploadTemp_RD    
  SET NOCOUNT ON;    
  declare @NumRecs int;    
  select @NumRecs=count(*) from CPE_UploadTemp_RD with (NoLock) where WaitingACK=-5;    
  if @NumRecs=0 begin    
    set rowcount 1800;     
    update CPE_UploadTemp_RD with (RowLock) set WaitingACK=-5;     
    set rowcount 0;    
  end    

  -- Move records to CPE_RewardDistribution    
  insert into CPE_RewardDistribution with (RowLock) (LocalID, ServerSerial, LocationID, IncentiveID, RewardOptionID, Phase, CustomerPK, DistributionDate, LogixTransNum, PresentedCustomerID, PresentedCardTypeID, ResolvedCustomerID, HHID, Deleted, LastUpdate, WaitingACK, LastServerID, POSTimeStamp)     
    select Col1, Col2, Col9, Col3, Col4, Col5, Col6, Col7, Col8, Col10, Col11, Col12, Col13, 0 as Deleted, getdate() as LastUpdate, -5 as WaitingACK, ServerSerial as LastServerID, POSTimeStamp from CPE_UploadTemp_RD with (NoLock)     
    where WaitingACK=-5;    

  -- Move records to CPE_RD_Output    
  insert into CPE_RD_Output with (RowLock) (LocalID, ServerSerial, IncentiveID, RewardOptionID, Phase, CustomerPK, DistributionDate, Deleted, LastUpdate, WaitingACK, TargetLocationID, POSTimeStamp)

    from CPE_UploadTemp_RD as BT with (NoLock) Inner Join CustomerLocations as CL with (NoLock) on BT.Col6=CL.CustomerPK and not(CL.LocationID=BT.LocationID) and BT.WaitingACK=-5;    

  Delete from CPE_UploadTemp_RD with (RowLock) where WaitingACK=-5;    

END
GO
GRANT EXECUTE ON [dbo].[pa_CPE_TUA_RD] TO [Copient_Logix_uspRole] AS [dbo]
