Tsql 使用多列时不存在

我正在尝试查找我的#tentable中不在staging表中的所有记录。 需要注意的是，比较需要在16个字段上进行

我试过几种组合，但似乎都不起作用

    SELECT CustomerAccountNo FROM #TempTable        
    WHERE NOT EXISTS
    (SELECT e.[CustomerAccountNo] ,
    e.[MeterNo] ,
    e.[CustomerName1] ,
    e.[ServiceAddress1] ,
    e.[ServiceAddress2] ,
    e.[ServiceCity] ,
    e.[ServiceState] ,
    e.[ServiceZip] ,
    e.[BillingAddress1] ,
    e.[BillingAddress2] ,
    e.[BillingAddress3] ,
    e.[BillingCity] ,
    e.[BillingState] ,
    e.[BillingZip] ,
    e.[BillingZip4] ,
    e.[PrimaryPhoneNumber] FROM #TempTable e
    JOIN dbo.Staging s
    ON e.CustomerAccountNo = s.CustomerAccountNo AND
    e.MeterNo = s.MeterNo AND
    e.CustomerName1 = s.CustomerName1 AND
    e.ServiceAddress1 = s.ServiceAddress1 AND
    e.ServiceAddress2 = s.ServiceAddress2 AND
    e.ServiceCity = s.ServiceCity AND
    e.ServiceState = s.ServiceState AND
    e.ServiceZip = s.ServiceZip AND
    e.BillingAddress1 = s.BillingAddress1 AND
    e.BillingAddress2 = s.BillingAddress2 AND
    e.BillingAddress3 = s.BillingAddress3 AND
    e.BillingCity = s.BillingCity AND
    e.BillingState = s.BillingState AND
    e.BillingZip = s.BillingZip AND
    e.BillingZip4 = s.BillingZip4 AND
    e.PrimaryPhoneNumber= s.PrimaryPhoneNumber          
    )

只需进行连接并查找null。像这样

SELECT e.*
 FROM #TempTable e
 LEFT JOIN dbo.Staging s
    ON e.CustomerAccountNo = s.CustomerAccountNo AND
    e.MeterNo = s.MeterNo AND
    e.CustomerName1 = s.CustomerName1 AND
    e.ServiceAddress1 = s.ServiceAddress1 AND
    e.ServiceAddress2 = s.ServiceAddress2 AND
    e.ServiceCity = s.ServiceCity AND
    e.ServiceState = s.ServiceState AND
    e.ServiceZip = s.ServiceZip AND
    e.BillingAddress1 = s.BillingAddress1 AND
    e.BillingAddress2 = s.BillingAddress2 AND
    e.BillingAddress3 = s.BillingAddress3 AND
    e.BillingCity = s.BillingCity AND
    e.BillingState = s.BillingState AND
    e.BillingZip = s.BillingZip AND
    e.BillingZip4 = s.BillingZip4 AND
    e.PrimaryPhoneNumber= s.PrimaryPhoneNumb
    WHERE s.CustomerAccountNo is null

你应该提供更详细的情况以得到正确的答案

显然，FROM子句和WHERE子句之间没有任何连接，因此查询将返回所有

试试这个：

SELECT CustomerAccountNo FROM #TempTable t       
WHERE NOT EXISTS
    (SELECT 1 FROM dbo.Staging s WHERE
    t.CustomerAccountNo = s.CustomerAccountNo AND
    t.MeterNo = s.MeterNo AND
    t.CustomerName1 = s.CustomerName1 AND
    t.ServiceAddress1 = s.ServiceAddress1 AND
    t.ServiceAddress2 = s.ServiceAddress2 AND
    t.ServiceCity = s.ServiceCity AND
    t.ServiceState = s.ServiceState AND
    t.ServiceZip = s.ServiceZip AND
    t.BillingAddress1 = s.BillingAddress1 AND
    t.BillingAddress2 = s.BillingAddress2 AND
    t.BillingAddress3 = s.BillingAddress3 AND
    t.BillingCity = s.BillingCity AND
    t.BillingState = s.BillingState AND
    t.BillingZip = s.BillingZip AND
    t.BillingZip4 = s.BillingZip4 AND
    t.PrimaryPhoneNumber= s.PrimaryPhoneNumber          
    )

它怎么不起作用？你的唱片太多了吗？还不够？或者…？在这个代码组合中，我得到了所有的记录。好像什么都不见了。在其他人身上，我什么也得不到…@HABO-他们在那里，我从#诱人的e JOIN dbo看到他们

。Staging s

它需要是一个

外部

连接。否则ON子句怎么能工作？@AaronBertrand-是的，我省略了

left

。（如果你必须留下一些东西，我想是吧。）where子句只考虑16个字段中的1个。我需要确保所有16个字段都“不在”

SELECT CustomerAccountNo FROM #TempTable t       
WHERE NOT EXISTS
    (SELECT 1 FROM dbo.Staging s WHERE
    t.CustomerAccountNo = s.CustomerAccountNo AND
    t.MeterNo = s.MeterNo AND
    t.CustomerName1 = s.CustomerName1 AND
    t.ServiceAddress1 = s.ServiceAddress1 AND
    t.ServiceAddress2 = s.ServiceAddress2 AND
    t.ServiceCity = s.ServiceCity AND
    t.ServiceState = s.ServiceState AND
    t.ServiceZip = s.ServiceZip AND
    t.BillingAddress1 = s.BillingAddress1 AND
    t.BillingAddress2 = s.BillingAddress2 AND
    t.BillingAddress3 = s.BillingAddress3 AND
    t.BillingCity = s.BillingCity AND
    t.BillingState = s.BillingState AND
    t.BillingZip = s.BillingZip AND
    t.BillingZip4 = s.BillingZip4 AND
    t.PrimaryPhoneNumber= s.PrimaryPhoneNumber          
    )
