Answer 1

Im not sure on the Group by part because of the aggregate but, you can try this:

 SELECT A.Docentry, A.Transtype, A.LotQty 
 FROM your_table as A 
 WHERE A.ItemCode IN 
    (SELECT B.ItemCode 
      FROM your_table as B 
      WHERE SUM(B.LotQty) = 0 
      GROUP BY B.ItemCode)

Answer 2

您可以使用ABS函数获取绝对值并进行比较。

Select * from Table T1 join Table T2 Where ABS(T1.LotQty)<>ABS(T2.LotQty)
