Question

我有一张桌子发票。我需要排除所有具有round( sum(QtyInvoiced),1) = 0 and round(sum(Amount),1) =0

的行

我尝试了两个使用不同过滤器的查询：

查询1：返回12745行

select sum(    QtyInvoiced ) , sum(Amount) ,salesNumber 
    from invoicesales
   group by salesNumber 
having round( sum(QtyInvoiced),1) <> 0 and round(sum(Amount),1)<>0

查询2 ：：比Query1多返回13265行

 select sum(    QtyInvoiced ) , sum(Amount) ,salesNumber 
        from invoicesales
       group by salesNumber 
    HAVING NOT(ROUND( SUM(QtyInvoiced),1) = 0 AND ROUND(SUM(Amount),1) = 0);

我不明白两个过滤器之间的区别是什么？

Answer 1

您的second查询可能有结果，在会议either of conditions中，first查询将只有在会议both conditions中有结果。

如果您希望看到发票金额为正数时，我想您的sum(quantity)是销售和退货净额。因此，如果您还想查看净值为0的数量，请使用第二个查询

如果您只想看到同时满足两个条件的行，请使用第一个查询。这是示例

declare @table table (Salesnumber Int, QtyInvoiced  int,Amount money )
insert @table
select 1 ,2,20 union all
select 1 ,1,-10 union all
select 1 ,1,0 union all
select 2 ,2,20 union all
select 2 ,2,20 union all
select 2 ,2,20 union all
select 3 ,2,20 union all
select 3 ,1,-10 union all
select 4 ,1,0 union all
select 5 ,2,-20 union all
select 5 ,2,-20 union all
select 5 ,2,20 
--select * from @table
select sum(    QtyInvoiced ) Quantity , sum(Amount) Amount ,salesNumber 
    from @table
   group by salesNumber 
having round( sum(QtyInvoiced),1) <> 0 and round(sum(Amount),1)<>0

 select sum(    QtyInvoiced )Quantity  , sum(Amount) Amount ,salesNumber 
        from @table
       group by salesNumber 
    HAVING NOT(ROUND( SUM(QtyInvoiced),1) = 0 AND ROUND(SUM(Amount),1) = 0);
