错误消息-消息156，级别15，状态1，关键字“ WHERE”附近的语法不正确

Question

尝试执行以下SQL语句时遇到错误。 不知道WHERE周围是否还需要其他保留字或括号，但是我的想法已经用完了。

我收到错误消息-“消息156，级别15，状态1，行20关键字'WHERE'附近的语法不正确。”

谁能帮助我找出如何纠正此错误？

提前致谢！

Answer 1

您的查询中有一些不必要的JOIN（例如重复的INNER JOIN dbo.PURCHASING_DETAIL ）和一些无用的括号。 尝试这个：

SELECT  dbo.PURCHASING_DETAIL.ID,
        dbo.SCA_SS_INVOICELINESALL.*,
        dbo.SCA_SS_INVOICESALL.*,
        dbo.PURCHASING_DETAIL.QUOTEDPRICE,
        dbo.PURCHASING_DETAIL.GLACCT,
        dbo.PURCHASING_DETAIL.[PO DATE]
FROM    dbo.PURCHASING_DETAIL
JOIN    dbo.SCA_SS_INVOICELINESALL
    ON  dbo.SCA_SS_INVOICELINESALL.SUPPARTNUM = dbo.PURCHASING_DETAIL.SUPPARTNUM 
JOIN    dbo.SCA_SS_INVOICESALL      
    ON  dbo.SCA_SS_INVOICESALL.INVOICENUMBER = dbo.PURCHASING_DETAIL.INVOICENUM
JOIN    dbo.SCA_SS_LOCATION
    ON  dbo.SCA_SS_INVOICESALL.SHIPTOADDRID = dbo.SCA_SS_LOCATION.LOCATIONID AND
        dbo.PURCHASING_DETAIL.FACILITY = dbo.SCA_SS_LOCATION.FACILITYID
WHERE   dbo.PURCHASING_DETAIL.[6DIGIT] = '50002'
        AND DATEDIFF(month,[PO DATE], GETDATE()) <= 12

Answer 2

您还具有一些JOIN表达式，这些表达式引用不在联接中的表。 这些可能应该在WHERE子句中。 可以，但是很难阅读。

我也同意您应该删除所有括号。

另外，正如我在评论中提到的，您有两次Purchasing_Detail。

尝试这个：

SELECT  dbo.PURCHASING_DETAIL.ID,
        dbo.SCA_SS_INVOICELINESALL.*,
        dbo.SCA_SS_INVOICESALL.*,
        dbo.PURCHASING_DETAIL.QUOTEDPRICE,
        dbo.PURCHASING_DETAIL.GLACCT,
        dbo.PURCHASING_DETAIL.[PO DATE]

FROM    dbo.SCA_SS_INVOICELINESALL

    INNER JOIN dbo.SCA_SS_INVOICESALL
        ON dbo.SCA_SS_INVOICELINESALL.INVOICESALLID = dbo.SCA_SS_INVOICESALL.INVOICESALLID

    INNER JOIN dbo.PURCHASING_DETAIL
        ON dbo.SCA_SS_INVOICELINESALL.SUPPARTNUM = dbo.PURCHASING_DETAIL.SUPPARTNUM 

    INNER JOIN dbo.SCA_SS_LOCATION
         ON (dbo.SCA_SS_INVOICESALL.SHIPTOADDRID = dbo.SCA_SS_LOCATION.LOCATIONID)

WHERE (dbo.PURCHASING_DETAIL.[6DIGIT] = '50002')
    AND (dbo.SCA_SS_INVOICESALL.INVOICENUMBER = dbo.PURCHASING_DETAIL.INVOICENUM)
    AND (dbo.PURCHASING_DETAIL.FACILITY = dbo.SCA_SS_LOCATION.FACILITYID)
    AND DATEDIFF(month,[PO DATE], GETDATE()) <= 12
