Mysql 用“选择”按钮选择位置？

我有一个查询，发现所有未清余额不等于0的人。我认为这一切都是好的，但扩大了可用的样本数据后，我发现它并不完全存在，我想不远

代码如下：

    SELECT bookingRef, leadname, departureDate, balanceDueDate,
      totalDue, totalReceived, (totalDue - totalReceived) AS outstandingBalance,
      (SELECT SUM(CASE WHEN(totalDue - totalReceived) <> 0 THEN 1 ELSE 0 END)
       FROM bookings) AS numberOutstanding,
      (SELECT SUM(totalDue) FROM bookings) AS grossDue,
      (SELECT SUM(totalReceived) FROM bookings) AS grossReceived,
      (SELECT SUM(totalDue - totalReceived) FROM bookings) AS grossOutstanding
    FROM bookings
    WHERE (amendedDate BETWEEN '2015-09-30' AND '2016-09-30')
    HAVING outstandingBalance <> 0;

发生的情况是，当日期在整个范围内时，结果是正确的。但是，当只执行上述一年时，它仍然对总范围进行求和，忽略求和的where子句

我想我需要将where子句添加到每个sum select中，但仍会遇到运行错误

我将如何实现这一点

非常感谢

注意：使用MySQL 8-10年而不使用它时非常生锈。

没有MySQL窗口功能的解决方案 不幸的是，MySQL不支持窗口函数，这将使此查询更加方便。相反，您可以在案例中使用交叉联接。不过，由于MySQL也不支持公共表表达式，您将无法避免两次应用谓词：

SELECT b.bookingRef, b.leadname, b.departureDate, b.balanceDueDate,
  b.totalDue, b.totalReceived, (b.totalDue - b.totalReceived) AS outstandingBalance, a.*
FROM bookings b,
CROSS JOIN (
  SELECT 
    SUM(CASE WHEN(totalDue - totalReceived) <> 0 THEN 1 ELSE 0 END AS numberOutstanding,
    SUM(totalDue) AS grossDue,
    SUM(totalREceived) AS grossReceived,
    SUM(totalDue - totalReceived) AS grossOutstanding
  FROM bookings
  WHERE (amendedDate BETWEEN '2015-09-30' AND '2016-09-30')
  AND (totalDue - totalReceived) <> 0
) a
WHERE (b.amendedDate BETWEEN '2015-09-30' AND '2016-09-30')
AND (b.totalDue - b.totalReceived) <> 0;

关于拥有的旁注

我怀疑您使用HAVING子句是为了能够重新使用SELECT子句中的列名。这是非常特定于MySQL的，可能并不完全符合您的意图。HAVING在GROUP BY之后应用，因此在聚合之后应用。在您的查询中，您并不真正需要GROUP BY子句，因此我将避免使用HAVE

非常感谢，阻止我拔头发。

SELECT bookingRef, leadname, departureDate, balanceDueDate,
  totalDue, totalReceived, (totalDue - totalReceived) AS outstandingBalance,
  SUM(CASE WHEN(totalDue - totalReceived) <> 0 THEN 1 ELSE 0 END) OVER() AS numberOutstanding,
  SUM(totalDue) OVER() AS grossDue,
  SUM(totalReceived) OVER() AS grossReceived,
  SUM(totalDue - totalReceived) OVER() AS grossOutstanding
FROM bookings
WHERE (amendedDate BETWEEN '2015-09-30' AND '2016-09-30')
AND (b.totalDue - b.totalReceived) <> 0;
