Question

我有两张桌子，

 Invoice (ordernumber, status(which assign to InvoiceStatuses), etc)

和

InvoiteStatuses(status name, statusid)

我需要仅针对OrderNumber检查Invoice中的重复项，但是where status != statusID（其中名称为“CANCELED”）

SELECT A.*
FROM Invoices A
JOIN InvoiceStatuses b 
 (
   SELECT * FROM InvoiceStatuses  
   WHERE InvoiceStatus = 'CANCELLED'
 ) B
ON A.InvoiceStatus!=b.InvoiceStatusID
WHERE exists (SELECT OrderNumber
    FROM Invoices c
    WHERE a.OrderNumber = c.OrderNumber
    GROUP BY OrderNumber
    HAVING COUNT(*)>1)

Answer 1

我认为您需要在查询中进行以下更改

JOIN子句过滤取消的状态out和where子句以仅检索重复的

SELECT A.*
FROM Invoices A
WHERE exists (SELECT OrderNumber
              FROM Invoices c
                 JOIN InvoiceStatuses b 
                 ON c.InvoiceStatus=b.InvoiceStatusID 
                    AND InvoiceStatus != 'CANCELLED'
              WHERE a.OrderNumber = c.OrderNumber
              GROUP BY OrderNumber
              HAVING COUNT(*)>1)

显示使用Where复制SQL
