Question

我正在编写此查询，原始查询返回272行

SELECT
i.InvoiceId
,i.AccountCode AS ClientAccountCode FROM 
vwInvoicesToSend i
    JOIN 
[SmartAdmin].dbo.Customers c ON i.AccountCode = c.AccountCode COLLATE DATABASE_DEFAULT
    JOIN 
InvoiceImages ii  ON i.invoiceid = ii.invoiceid WHERE 
i.BillRunId = 140 
    AND
c.BusinessGroup = 'xxxNZ'

我也有这个子查询返回5795行

WITH base AS (
SELECT Email, MAX(AccountCode) AS AccountCode FROM [SMPro5Profile].dbo.vwPFD_0000001848 WHERE AccountCode IS NOT NULL GROUP BY Email,AccountCode)

当我尝试在这两个查询之间执行内部联接时，我希望看到不超过272行。但我得到了1824行。

WITH base AS (SELECT Email, MAX(AccountCode) AS AccountCode FROM [SMPro5Profile].dbo.vwPFD_0000001848 WHERE AccountCode IS NOT NULL GROUP BY Email,AccountCode )  SELECT
i.InvoiceId
,i.AccountCode AS ClientAccountCode
--,base.AccountCode
--,base.[Email] FROM 
vwInvoicesToSend i
    JOIN 
[SmartAdmin].dbo.Customers c ON i.AccountCode = c.AccountCode COLLATE DATABASE_DEFAULT
    JOIN 
InvoiceImages ii  ON i.invoiceid = ii.invoiceid 
    INNER JOIN
base ON base.AccountCode = i.AccountCode COLLATE DATABASE_DEFAULT WHERE 
i.BillRunId = 140 
    AND
c.BusinessGroup = 'xxxNZ'

我怀疑异常是由于COLLATE DATABASE_DEFAULT，因为两个引用列具有不同的归类定义。

无法解决＆＃34; SQL_Latin1_General_CP1_CI_AS＆＃34;之间的整理冲突和＆＃34; Latin1_General_CI_AS＆＃34;在等于操作。

有人知道如何解决这个问题吗？谢谢:)）

COLLATE DATABASE_DEFAULT JOIN返回太多行
