SQL错误 "The ORDER BY clause is invalid in views..."

Question

我正在尝试解决一个SQL Server错误。有人可以帮我吗？
查询是:

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 NOT c.id IN ( 
SELECT TOP 10 tblclassifieds.id 
FROM tblclassifieds 
WHERE (c.expirydate != '') 
ORDER BY inserteddate desc) 
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 NOT ce.id IN ( 
SELECT TOP 10 tblclassifiedemployers.id 
FROM tblclassifiedemployers 
WHERE (ce.expirydate != '') 
ORDER BY inserteddate desc) 
ORDER BY inserteddate desc; 

错误:

The ORDER BY clause is invalid in views, inline functions, derived tables, subqueries, and common table expressions, unless TOP or FOR XML is also specified.

Answer 1

如前所述，除非使用TOP或FOR XML，否则ORDER BY不得出现在子查询中。

    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 NOT c.id IN ( 
        SELECT TOP 10 
            tblclassifieds.id 
        FROM tblclassifieds 
        WHERE c.expirydate != ''
        ORDER BY inserteddate desc 
    ) 
    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 NOT ce.id IN ( 
        SELECT TOP 10 
            tblclassifiedemployers.id 
        FROM tblclassifiedemployers 
        WHERE ce.expirydate != ''
        ORDER BY inserteddate desc
    )
) a ORDER BY inserteddate desc;
