Sql 从联合计算第二页结果

我遇到了SQLServer问题

我正在尝试如何显示第二页的结果。结果的第一页是使用下面的查询获取的

SELECT TOP 10 * FROM (
    SELECT c.id, c.name, c.inserteddate, c.cityname, ftblstates.name AS statename, clc.name AS catname, '' AS listingimagelogo, '' AS orgname, relocateyn, '' AS employerclassified
    FROM tblclassifieds c
    LEFT JOIN tblclassifiedscategories clc ON c.categoryid = clc.id
    LEFT JOIN ftblstates ON c.stateid = ftblstates.id
    WHERE c.expirydate != '' AND c.expirydate >= '5/17/2011'
    UNION ALL
    SELECT ce.id, ce.name, ce.inserteddate, suburb AS cityname, ftblstates.name AS statename, ce.jobtype AS catname, ce.listingimagelogo, ce.orgname, '' AS relocateyn, '1' AS employerclassified
    FROM tblclassifiedemployers ce
    LEFT JOIN ftblstates ON ce.stateid = ftblstates.id
    WHERE ce.expirydate != '' AND ce.expirydate >= '5/17/2011'
) a
ORDER BY inserteddate desc;

答案与下面的类似吗

SELECT TOP 10 * FROM (
    SELECT c.id, c.name, c.inserteddate, c.cityname, ftblstates.name AS statename, clc.name AS catname, '' AS listingimagelogo, '' AS orgname, relocateyn, '' AS employerclassified
    FROM tblclassifieds c
    LEFT JOIN tblclassifiedscategories clc ON c.categoryid = clc.id
    LEFT JOIN ftblstates ON c.stateid = ftblstates.id
    WHERE c.expirydate != '' AND c.expirydate >= '5/17/2011'
    UNION ALL
    SELECT ce.id, ce.name, ce.inserteddate, suburb AS cityname, ftblstates.name AS statename, ce.jobtype AS catname, ce.listingimagelogo, ce.orgname, '' AS relocateyn, '1' AS employerclassified
    FROM tblclassifiedemployers ce
    LEFT JOIN ftblstates ON ce.stateid = ftblstates.id
    WHERE ce.expirydate != '' AND ce.expirydate >= '5/17/2011'
) a

WHERE NOT a.id IN (SELECT TOP 10 tblclassifieds.id ...

ORDER BY inserteddate desc;

有人能帮我完成这个查询吗？

一个简单的方法：

declare @page int = 2
declare @take int = 10

select * from (
    SELECT *, ROW_NUMBER() OVER(ORDER BY inserteddate desc) as rowno FROM (
        SELECT c.id, c.name, c.inserteddate, c.cityname, ftblstates.name AS statename, clc.name AS catname, '' AS listingimagelogo, '' AS orgname, relocateyn, '' AS employerclassified
        FROM tblclassifieds c
        LEFT JOIN tblclassifiedscategories clc ON c.categoryid = clc.id
        LEFT JOIN ftblstates ON c.stateid = ftblstates.id
        WHERE c.expirydate != '' AND c.expirydate >= '5/17/2011'
        UNION ALL
        SELECT ce.id, ce.name, ce.inserteddate, suburb AS cityname, ftblstates.name AS statename, ce.jobtype AS catname, ce.listingimagelogo, ce.orgname, '' AS relocateyn, '1' AS employerclassified
        FROM tblclassifiedemployers ce
        LEFT JOIN ftblstates ON ce.stateid = ftblstates.id
        WHERE ce.expirydate != '' AND ce.expirydate >= '5/17/2011'
    ) a
) b
where   rowno > (@page - 1) * @take 
    AND rowno <= @page * @take
order by rowno

我没有改变你的内部询问

编辑：在where子句中添加了parentese

，看起来您可能正在尝试制定分页SQL查询的常规模式。如果是这样的话，您的问题可能是@mu引用的问题的副本，它比我上面提到的问题更具体。但请注意，这两个问题的答案都需要使用row_number函数，该函数在SQL Server>=2005中提供。对于旧版本，您唯一的工具是选择TopN，如示例中所示。假设需要第四页，每页10行，则需要1选择所有行，按所需顺序排序。2添加行以选择前4*10行，按相反顺序排序；3添加更多行以查询，从这40行中选择前10行，这次按所需顺序排序。@Joel:那么我想问题是Ben有哪个版本的SQL Server？非常感谢Johan的帮助！您为我节省了很多时间：我只需要做一些更改，就可以让页面显示正确数量的结果。在rowno>@page*@take-@take和rowno Ok的地方，我现在明白了，我应该把parenteses和@page-1放在一起，让它工作，但是你的解决方案工作得很好。
