複数の場所で在庫品目を更新するストアド プロシージャがあります。私が主にやろうとしているのは、場所間の在庫移動の適切な記録管理を可能にすることです.
私が直面している問題は、これらの場所のいくつかにはほとんどの種類の在庫品目の記録がないため、数量を更新しようとすると (開始場所から -1、新しい場所に +1) 記録がないことです。アップデート。
これが私のストアドプロシージャです:
CREATE procedure dbo.Inv_Transfer (@p_hStock numeric,
@p_sFProp varchar(20), @p_hTProp numeric,
@p_dQuan numeric, @p_Date datetime,
@p_sUser1 varchar(1000),@p_sUser2 varchar(1000))
as
declare
@v_FInvhMy numeric,
@v_TInvhMy numeric,
@v_sStockCode varchar(10),
@v_hFProp numeric,
@v_ibegin int,
@v_iend int
begin
set @v_ibegin = charindex('(', @p_sFProp )
if @v_ibegin <= 0
begin
raiserror('From property string not readable',16,1, @p_sFProp )
return(0)
end
else
begin
set @v_iend = charindex (')',@p_sFProp)
set @v_hFProp = substring(@p_sFProp,@v_ibegin + 1,@v_iend - @v_ibegin -1)
end
select @v_sStockCode = sCode from mm2stock where hMy = @p_hStock
if @@ERROR<> 0
begin
raiserror('Stock read failed ',16,1)
return(0)
end
select @v_FInvhMy = hMy from mm2inventory where hStock = @p_hStock and hStoreProp = @v_hFprop
if @@ERROR<> 0
begin
raiserror('From inventory read failed ',16,1)
return(0)
end
select @v_TInvhMy = hMy from mm2inventory where hstock = @p_hStock and hStoreProp = @p_hTProp

end
update mm2inventory set iQtyonHand = iQtyonHand + @p_dquan where hmy = @v_TInvhMy
if @@ERROR<> 0
begin
raiserror('Update to inventory failed ',16,1)
return(0)
end
else
begin
INSERT INTO mm2inventory (scode, hstock, hstoreprop, dcosteach, dbillprice, ireorderlevel, ireorderqty, iqtyonorder, iqtyonhand, suser1, suser2, suser3, suser4, snotes)

update mm2inventory set iQtyonHand = iQtyonHand + @p_dquan where hmy = @v_TInvhMy
end
insert into mm2InvXfer( sStock,hinvfrom,hinvto,dquant,dtdate,sUser1,sUser2)
values (@v_sStockCode,@v_FinvhMy, @v_TInvhMy, @p_dquan,

end
私が取り組んでいることの抜粋:
update mm2inventory set iQtyonHand = iQtyonHand - @p_dquan where hmy = @v_FInvhMy
if @@ERROR<> 0
begin
raiserror('Update from inventory failed ',16,1)
return(0)
end
update mm2inventory set iQtyonHand = iQtyonHand + @p_dquan where hmy = @v_TInvhMy
if @@ERROR<> 0
begin
raiserror('Update to inventory failed ',16,1)
return(0)
end
else
begin
INSERT INTO mm2inventory (scode, hstock, hstoreprop, dcosteach, dbillprice, ireorderlevel, ireorderqty, iqtyonorder, iqtyonhand, suser1, suser2, suser3, suser4, snotes)
SELECT (SELECT hmy + 1 where hmy in (select max(hmy) from mm2inventory)),@p_hStock,@p_hTProp,(SELECT dcosteach from mm2inventory where hstock = @p_hStock and hstoreprop = @v_hFProp),(SELECT dbillprice from mm2inventory where hstock = @p_hStock and hstoreprop = @v_hFProp),(SELECT ireorderlevel from mm2inventory where hstock = @p_hStock and hstoreprop = @v_hFProp),(SELECT ireorderqty from mm2inventory where hstock = @p_hStock and hstoreprop = @v_hFProp),0,0,'','','','','' FROM mm2inventory
update mm2inventory set iQtyonHand = iQtyonHand + @p_dquan where hmy = @v_TInvhMy
end
上記のように、更新しようとしています (両方の保管場所の在庫品目のレコードが存在する場合は正常に機能します) が、エラーが発生した場合は、その特定の在庫品目に新しい行を挿入してから、新しい数量値で更新しますが、間違ったことをしています。
誰が私が間違っているのか教えてもらえますか? ありがとう
