while循環SAP B1 SQL存儲過程阻塞

Question

我的存儲過程SAP B1有問題。

我在這裏要做的是存儲數量的總和，按製造訂單分組，並將其插入臨時表中。然後使用while循環遍歷每個ID以與用戶表格[@FGTRACKING]進行比較，並在[[FGTracking]中設置 temp.quantity> sum（quantity）]。

但是這不起作用，事務仍然通過存儲過程塊。我懷疑我的語法有問題。

IF @transaction_type IN ('A') AND @object_type = '67' 
    BEGIN 
    declare @top as int 
    declare @temp table (id int,quantity int NOT NULL, monum int NOT NULL) 
    insert into @temp (id, quantity,monum) 
    select row_number() over (order by (select NULL)), sum(quantity) as quantity, u_shipment_line as monum 
    from wtr1 t1 
    where t1.docentry = @list_of_cols_val_tab_del 
    group by u_shipment_line 
    set @top = 1 
    WHILE @top <= (select count(monum) from @temp) 
    BEGIN 
    IF EXISTS (select t100.monum from @temp t100 
    where t100.quantity > (select sum(t111.u_transfer) 
    from [@FGTRACKING] t111 where t111.u_mo_num = t100.monum 
    group by t111.u_mo_num) and t100.id = @top) 
    BEGIN 
    SELECT @Error = 666, @error_message = 'Over-transfer' 
    END 
    ELSE 
    set @top = @top + 1 
    END 
    END

它看起來像你只是增加你的迭代器（@top）當你沒有遇到你的錯誤情況，所以如果你的錯誤條件觸發，你停留在一個無限循環。

擺脫「其他」並始終增加@top，或者在達到錯誤條件時跳出while循環。

ELSE -- Get rid of this else 
set @top = @top + 1
