Question

WHILE @Suma < @ZalihaVP
begin
    Insert into @Promet (Kljuc, Kolicina, Datum, StarostPrometa)
    select top 1 m.acKey, anQTY, m.adDate, DATEDIFF(d, m.adDate, getdate())
    from tHE_Move m inner join tHE_MoveItem mi
    on m.acKey = mi.acKey
    where acReceiverStock = 'Y'
    and acReceiver = @Skladiste
    and acIdent = @Ident
    and m.acKey not in(select Kljuc from @Promet)
    order by adDate desc

    set @Suma = @Suma + (select SUM(kolicina) from @Promet)

    if @Suma > @ZalihaVP begin update @Promet set Kolicina = Kolicina - (@Suma - @ZalihaVP) where KLjuc = (select top 1 KLjuc from @Promet order by Datum) end
    if @Suma > @ZalihaVP begin set @Suma = @ZalihaVP end
end

这是我的WHILE循环，我在这里遇到问题。 @ZalihaVP = 92 @Suma = 0

@ promet.kolicina的记录是：40,50,50

在第三张唱片上，@ Suma比@ZalihaVP 40 + 50 + 50 = 140＆gt; @Suma 和第三个记录没有插入，但我希望它们插入。

我如何发送@Suma＆lt; @Zaliha插入后结束了吗？

Answer 1

我认为问题在于这一行：

set @Suma = @Suma + (select SUM(kolicina) from @Promet)

您将@Suma设置为自身加上所有kolicina合并。

也许应该是：

set @Suma = select SUM(kolicina) from @Promet
