以下查询；

   DECLARE  @uname VARCHAR(10) = 'Dom',
        @pword VARCHAR(10) = 'Python',
        @sntype VARCHAR(1) = 'B',
        @action VARCHAR(10) = 'INSERT',
        @salesContractRef VARCHAR(10) = '',
        @auctionId NCHAR(10) = '';

SELECT
    RTRIM(@uname) AS '@uname',
    RTRIM(@pword) AS '@pword',

    (SELECT
    LandingId AS '@landingId',
        @snType AS '@snType',
        RTRIM(@action) AS '@action',
        COALESCE(@salesContractRef, '') AS '@salesContractRef',
        CONVERT(VARCHAR(10), DateOfPurchase, 112) AS '@saleDate',
        RTRIM(COALESCE(@auctionID, '')) AS '@auctionID',
        ISNULL(Logbook1 + ',', '') + ISNULL(Loogbook2 + ',', '') + ISNULL(Logbook3 + ',', '') AS '@logBookNums',

        COALESCE(CONVERT(VARCHAR(10), LandingDate1, 112), '') AS '@landingDate1',
        COALESCE(CONVERT(VARCHAR(10), LandingDate2, 112), '') AS '@landingDate2',
        COALESCE(CONVERT(VARCHAR(10), LandingDate3, 112), '') AS '@landingDate3',
        RTRIM(CountryOfLanding) AS '@countryOfLanding',
        RTRIM(PortOfLanding) AS '@portOfLanding',
        (SELECT
            LandingDetails.LandingId AS '@landingId',
            SpeciesCode AS '@speciesCode',
            RTRIM(FishingArea) AS '@faoAreaCode',
            RTRIM(IcesZone) AS '@ZoneCode'
        FROM Landings.LandingDetails
        INNER JOIN Landings.LandingHeaders lh
            ON Landings.LandingDetails.LandingId = lh.LandingId
            WHERE lh.Posted = 0


        FOR XML PATH ('detail'), TYPE)

    FROM Landings.LandingHeaders
    JOIN Landings.Vessels
        ON Landings.LandingHeaders.VesselId = Vessels.VesselId
        WHERE Posted = 0
    FOR XML PATH ('sale'), TYPE)
FOR XML PATH ('abc')

产生这个输出；

    <abc uname="Dom" pword="Python">
  <sale landingId="3388" snType="B" action="INSERT" salesContractRef="" saleDate="20130706" auctionID="" logBookNums="L7014  ,L7015  ,L7016  ," landingDecNums="" landingDate1="20130705" landingDate2="" landingDate3="" countryOfLanding="GBR" portOfLanding="GBHTG">

    <detail landingId="3389" speciesCode="PLE" faoAreaCode="27" ZoneCode="VIID" />
  </sale>
</abc>

这几乎与我所希望的完全一样，除了两个销售行的详细信息行被重复，而实际上它们应该只出现在相关的销售行中。匹配landingid 显然是拉出了正确的细节线，只是不确定我缺少什么额外的小调整。

谢谢

编辑：将 SQL 查询更改为以下内容；

DECLARE @uname VARCHAR(10) = 'Dom',
        @pword VARCHAR(10) = 'Python',
        @sntype VARCHAR(1) = 'B',
        @action VARCHAR(10) = 'INSERT',
        @salesContractRef VARCHAR(10) = '',
        @auctionId NCHAR(10) = '';

SELECT
    RTRIM(@uname) AS '@uname',
    RTRIM(@pword) AS '@pword',

    (SELECT

        @snType AS '@snType',
        RTRIM(@action) AS '@action',
        COALESCE(@salesContractRef, '') AS '@salesContractRef',
        CONVERT(VARCHAR(10), DateOfPurchase, 112) AS '@saleDate',
        RTRIM(COALESCE(@auctionID, '')) AS '@auctionID',
        ISNULL(Logbook1 + ',', '') + ISNULL(Loogbook2 + ',', '') + ISNULL(Logbook3 + ',', '') AS '@logBookNums',
        ISNULL(LandingDecNumber1 + ',', '') + ISNULL(LandingDecNumber2 + ',', '') + ISNULL(LandingDecNumber3 + ',', '') AS '@landingDecNums',

        COALESCE(CONVERT(VARCHAR(10), LandingDate1, 112), '') AS '@landingDate1',
        COALESCE(CONVERT(VARCHAR(10), LandingDate2, 112), '') AS '@landingDate2',
        COALESCE(CONVERT(VARCHAR(10), LandingDate3, 112), '') AS '@landingDate3',
        RTRIM(CountryOfLanding) AS '@countryOfLanding',
        RTRIM(PortOfLanding) AS '@portOfLanding',
        (SELECT

            SpeciesCode AS '@speciesCode',
            RTRIM(FishingArea) AS '@faoAreaCode',
            RTRIM(IcesZone) AS '@ZoneCode'


        FOR XML PATH ('detail'), TYPE)

    FROM Landings.LandingHeaders

    INNER JOIN Landings.LandingDetails ld
        ON Landings.LandingHeaders.LandingId = ld.LandingId

    WHERE Posted = 0

    FOR XML PATH ('sale'), TYPE)
FOR XML PATH ('abc')

现在产生以下输出；

    <abc uname="Dom" pword="Python">
  <sale snType="B" action="INSERT" salesContractRef="" saleDate="20130706" auctionID="" logBookNums="L7014  ,L7015  ,L7016  ," landingDecNums="" landingDate1="20130705" landingDate2="" landingDate3="" countryOfLanding="GBR" portOfLanding="GBHTG">

至少明细行现在与销售行匹配，但它为每个明细行生成单独的销售行。显然少了一点点。我尝试了 Group By LandingHeaders.LandingId 但这似乎会导致更多问题。

我认为这

WHERE lh.Posted = 0

应该换成这个

WHERE lh.Posted = 0 AND lh.LandingId=LandingId

如果它抱怨 LandingId 不明确，则添加别名，FROM Landings.LandingHeaders这样它就会像FROM Landings.LandingHeaders lh1然后尝试

WHERE lh.Posted = 0 AND lh.LandingId=lh1.LandingId
