SQL-使用附加条件筛选查询结果

我有一个包含两个表的数据库： -记录我必须收到的所有付款的信用证 -付款记录我收到的付款

结构是 信用：身份证，总计 付款：id，已收到

我的目标是有一个查询，打印所有尚未完全支付的付款。现在，我编写了一个查询，它成功地打印了 -信用证号码 -总金额请求 -收到的款项总额 我只需要添加一个条件：不要打印付款已全部完成的记录。这是我的SQL代码：

SELECT Credit.id,
       Credit.total,
       (SELECT SUM(Payment.received)
       FROM Payment WHERE Payment.id = Credit.id) AS TotalReceived
FROM Credit
WHERE Credit.total > 0;

我试着用“WHERE Credit.total>TotalReceived”来更改最后一行，但不起作用

你能帮我吗？：）

注：在信用证中，id是唯一的，而在付款表中，可以显示许多具有相同id的行。

除非使用子查询，否则不能为聚合列添加

WHERE

子句。您必须使用

分组依据

和

拥有

您的查询可以这样重写（我更喜欢使用联接的这种结构，而不是像您使用的那样使用关联查询）

SELECT Credit.id, Sum (Credit.total), SUM(Payment.received) TotalReceived
FROM Credit
INNER JOIN Payment ON Payment.id = Credit.id
WHERE Credit.total > 0
GROUP BY Credit.id

现在，添加一个

HAVING

子句

SELECT Credit.id, Sum (Credit.total), SUM(Payment.received) TotalReceived
FROM Credit
INNER JOIN Payment ON Payment.id = Credit.id
WHERE Credit.total > 0
GROUP BY Credit.id
HAVING SUM(Payment.received) > 0

如果您绝对希望保留您的结构，请使用如下子查询

Select Id, Total, TotalReceived
From
(
    SELECT Credit.id, Credit.total, (SELECT SUM(Payment.received)
    FROM Payment WHERE Payment.id = Credit.id) AS TotalReceived
    FROM Credit
    WHERE Credit.total > 0
) DerivedTable
Where TotalReceived > 0

这将为您获取尚未付款的信用记录。您的付款表可能应该有一个

creditId

字段来加入，而不是在

credit.id=payment.id

上，但如果它是这样设置的，那么这应该会起作用

SELECT  c.id,
        c.total,
        SUM(Nz(p.received,0)) AS totalreceived
FROM    Credit c
        LEFT JOIN Payment p ON c.id = p.id --not sure about this?
WHERE   c.total > 0
GROUP BY c.id, c.total
HAVING  c.total > SUM(Nz(p.received,0))
