If statement SQL Server 2005:查找一年内未订购的客户

我试图在SQLServer2005数据库中查找没有任何订单的客户名称，或者要求提供一年的报价。我正在尝试这一点，但它不起作用，因为它只显示超过一年的文档，但如果在当前一年中出现了相同客户的其他文档，也会显示它们

SELECT DISTINCT 
    ANAGRAFICACF.CODCONTO,
    DSCCONTO1,
    '€ '+LEFT(TOTDOCUMENTO,LEN(TOTDOCUMENTO)-2),
    CONVERT(VARCHAR(11),DATADOC,6),
    TESTEDOCUMENTI.TIPODOC,
    ANAGRAFICACF.PARTITAIVA,
    ANAGRAFICACF.CODFISCALE,
    ANAGRAFICARISERVATICF.NOTE1,
    TESTEDOCUMENTI.DATADOC,
    TESTEDOCUMENTI.CODAGENTE1,
    ANAGRAFICAAGENTI.DSCAGENTE 
FROM
    dbo.TESTEDOCUMENTI 
INNER JOIN 
    dbo.ANAGRAFICACF ON CODCLIFOR = CODCONTO
INNER JOIN 
    dbo.RIGHEDOCUMENTI ON PROGRESSIVO = IDTESTA AND TOTNETTORIGA <> '0'
INNER JOIN 
    dbo.ANAGRAFICARISERVATICF ON CODCLIFOR = ANAGRAFICARISERVATICF.CODCONTO
LEFT JOIN 
    dbo.ANAGRAFICAAGENTI ON CODAGENTE = TESTEDOCUMENTI.CODAGENTE1
WHERE  
    (dbo.TESTEDOCUMENTI.TIPODOC = 'ORDER' OR
     dbo.TESTEDOCUMENTI.TIPODOC = 'QUOTATION') 
    AND (dbo.TESTEDOCUMENTI.DATADOC < DATEADD(DAY, -365, GETDATE()) 

ORDER BY 
    TESTEDOCUMENTI.DATADOC DESC

解决方案谢谢@scsimon 将此where条件添加到NOT IN中：

    WHERE      dbo.TESTEDOCUMENTI.TIPODOC = 'FVC' AND dbo.TESTEDOCUMENTI.DATADOC < DATEADD(DAY, -365, GETDATE()) 
               AND TESTEDOCUMENTI.CODCLIFOR NOT IN (SELECT DISTINCT TESTEDOCUMENTI.CODCLIFOR
                    FROM dbo.TESTEDOCUMENTI  
                    WHERE dbo.TESTEDOCUMENTI.TIPODOC = 'FVC' AND dbo.TESTEDOCUMENTI.DATADOC > DATEADD(DAY, -365, GETDATE())
                    )

Hope this will help, if someone else will have my request. 

您要使用的文件不存在。如果ANAGRAFICACF.CODCONTO是您的客户编号，则以下内容适用于您。因为您的列名不是很自解释的，所以如果我不正确，请将它们更改为您需要的名称。但是，不存在的逻辑是你想要的

你的最后一个where子句似乎无关紧要。当你移除它时会发生什么是不相关的。我获得了相同的结果，但仍然是错误的结果，因为我获得了一个客户的名称，该客户在今年也有订单。我需要排除它们。订单日期是否仅基于dbo.TESTEDOCUMENTI.DATADOC是的，并且至少基于交货日期，但我认为使用它没有什么用处。然后仅使用和dbo.TESTEDOCUMENTI.DATADOC查询，另一次是<，我也会看到不同的客户代码。但是当我使用notexist时，结果是黑色的。还有另一个逗号用于排除结果？@BigBlack我给了你另一种使用NOT IN的方法。我还提供了一个示例数据集。这应该解决你的问题，所以考虑投票和接受它，以及我为你解决的另一个问题。

AND NOT dbo.TESTEDOCUMENTI.DATADOC BETWEEN DATEADD(DAY, -365, GETDATE() ) AND GETDATE())
