Question

select v.nroventa, sum(v.importe)
from ventas v, pagosventas p 
where v.nroventa=p.nroventa 
  and v.codigocliente=41 
  and v.nroventa not in (select p.nroventa 
                         from pagosventas p, ventas v 
                         where p.nroventa=v.nroventa)
group by v.nroventa

为什么这个查询错了？

我现在遇到语法错误，并且VB没有突出显示错误引发时错误的部分。

Answer 1

以下查询应该有效。尝试从sql server或任何sql ide运行它。

SELECT A.nroventa,A.sum_importe
FROM
(
select v.nroventa, sum(v.importe) AS sum_importe
from ventas v, pagosventas p 
where v.nroventa=p.nroventa 
  and v.codigocliente=41 
group by v.nroventa
) A,
(
SELECT v.nroventa
FROM ventas v
WHERE v.nroventa 
not in
(select p.nroventa from pagosventas p, ventas v where p.nroventa=v.nroventa)
) B
WHERE A.nroventa = B.nroventa;

Answer 2

我认为你还需要在select的第一个字段上使用agg函数，例如MAX（v.nroventa）

select MAX(v.nroventa), sum(v.importe)
from ventas v, pagosventas p 
where v.nroventa=p.nroventa 
and v.codigocliente=41 
and v.nroventa not in (select p.nroventa 
                     from pagosventas p, ventas v 
                     where p.nroventa=v.nroventa)
group by v.nroventa

使用NOT IN关键字的SQL查询
