mysql在where子句中使用逻辑+组函数的使用无效

我有下面的mysql查询，输出下图：

select
  v.invoicenumber,
  v.invoicedate,
  v.haulier,
  v.transporttype,
  count(v.loadnumber) as totalloads,
  sum(v.cost) as totalcost, 
  concat(SUM(if(invoiceapproved = 'yes', 1, 0)),' / ',count(v.loadnumber)) AS count,  SUM(if(invoiceapproved = 'yes', 1, 0)) as approved
from v2loads v  
  where v.invoiced='yes'   
  group by invoicenumber

此查询执行100%

我要做的是过滤掉计数为100%的任何行/数据。在示例输出中，我想过滤掉发票16，因为它是2/2和100%。那么在哪里呢

 count(v.loadnumber) <> SUM(if(invoiceapproved = 'yes', 1, 0))

如果我将此逻辑添加到where子句中，它将失败，错误为group函数的使用无效。所以下面的代码不起作用：

select v.invoicenumber,
  v.invoicedate,
  v.haulier,
  v.transporttype,
  count(v.loadnumber) as totalloads,
  sum(v.cost) as totalcost, 
  concat(SUM(if(invoiceapproved = 'yes', 1, 0)),' / ',count(v.loadnumber)) AS count, 
  SUM(if(invoiceapproved = 'yes', 1, 0)) as approved 
from v2loads v  
  where v.invoiced='yes' and 
  (count(v.loadnumber))<>(SUM(if(invoiceapproved = 'yes', 1, 0)))  
  group by invoicenumber

我得到了以下错误：

错误为1111-组函数的使用无效

任何建议都将一如既往地受到欢迎。

您可以这样做：

SELECT 
  *,
  CONCAT(approved, ' / ', totalloads) AS count, 
FROM
(
    SELECT
      v.invoicenumber,
      v.invoicedate,
      v.haulier,
      v.transporttype,
      COUNT(v.loadnumber)                    AS totalloads,
      SUM(v.cost)                            AS totalcost, 
      SUM(if(invoiceapproved = 'yes', 1, 0)) As approved 
    FROM v2loads v  
    WHERE v.invoiced='yes'
    GROUP BY invoicenumber
) t
WHERE totalloads <> approved;

您可以这样做：

SELECT 
  *,
  CONCAT(approved, ' / ', totalloads) AS count, 
FROM
(
    SELECT
      v.invoicenumber,
      v.invoicedate,
      v.haulier,
      v.transporttype,
      COUNT(v.loadnumber)                    AS totalloads,
      SUM(v.cost)                            AS totalcost, 
      SUM(if(invoiceapproved = 'yes', 1, 0)) As approved 
    FROM v2loads v  
    WHERE v.invoiced='yes'
    GROUP BY invoicenumber
) t
WHERE totalloads <> approved;
