Answer 1

我同意@lamak的问题。

但猜测：

Create proc [dbo].[SpGetPharmacyLogpast]
AS
SELECT  TOP 1 Pharmacylog.PharmcyItemID,Pharmacylog.PastQuantity,Pharmacylog.NowQuantity,Pharmacylog.Amount,Pharmacylog.TotalValue,PharmacyItems.ID  
from Pharmacylog 
LEFT JOIN PharmacyItems
ON  PharmacyItems.ID=Pharmacylog.PharmcyItemID 
where PharmacyItems.ItemID=8
ORDER BY Pharmacylog.PharmcyItemID DESC 
RETURN
