问题
I have a SQL Server error I'm trying to resolve. Could someone please help me out?
The query is:
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;
And the error: 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.
回答1:
As stated ORDER BY must not apper in subqueries unless TOP or FOR XML is used.
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;
回答2:
If you are using SQL Server 2012 or higher version, please use "offset 0 rows" after order by. Ex -
create view Department_View
as
select Name from [HumanResources].[Department]
order by Name offset 0 rows

I used the following construction:
SELECT
ROW_NUMBER() OVER (ORDER BY LASTNAME) SORTORDER,
*
FROM
CLIENT

I think it is self-explanatory. You can't use the ORDER BY clause in your sub-queries because they don't use a TOP or FOR XML.
When reviewing your code, I'm not sure I see the problem code though. All of the code looks correct. You are only using the ORDER BY in sub-queries that also employe the TOP command so they should all work. I would comment out all of the ORDER BY commands and then add them in one at a time until you find the one that throws the error. Maybe it doesn't like them because they are a sub-query of a sub-query.
Edit: Looking over it again, I think the problem is your IN statements. I don't believe you can use a sub-query with the ORDER BY when you are using IN.
Here is the code I would try:
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 != ''))
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 != '')))

CREATE FUNCTION GetUnitIDWithScenarioCount
(
@calculatorType int
)
returns TABLE as
return
(
select count,unitid from(
SELECT Top 1
count(sc.UnitId) as count, sc.unitid
FROM scenarios SC
INNER JOIN npcstatus NPC
ON NPC.UnitId=SC.UnitId
INNER JOIN IPEDSCollegeData..hd hd
ON hd.UnitId=NPC.UnitId
WHERE npc.calculatorType=4
Group by sc.unitid
) as temp
order by count
