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

我在尝试执行下面的 SQL 语句时运行遇到错误。不确定 WHERE 周围是否需要另一个保留字或括号，但我运行没主意了。

我收到错误消息——“消息 156，级别 15，状态 1，第 20 行关键字 'WHERE'."

附近的语法不正确

谁能帮我解决这个错误？

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。试试这个：

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

您还有一些 JOIN 表达式引用了不在联接中的表。这些可能应该在 WHERE 子句中。它会工作，但它真的很难阅读。

我也同意你应该删除所有括号。

此外，正如我在评论中提到的，您 Purchasing_Detail 两次。

试试这个：

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
