"'OFFSET'附近的语法不正确"modift sql comm 2012至2008

Question

我列出了这个问题

SELECT q.qTitle, q.qDescription, q.qCreatedOn, u.uCode, u.uFullname, qcat.qcatTitle, q.qId, q.qStatus 
FROM tblQuestion AS q INNER JOIN tblUser AS u 
ON q.uId = u.uId INNER JOIN tblQuestionCategory AS qcat 
ON q.qcatId = qcat.qcatId 
WHERE (q.qStatus = 1) 
ORDER BY q.qCreatedOn DESC 
OFFSET @page*10 ROWS FETCH NEXT 10 ROWS ONLY

但我的服务器出现问题,

Incorrect syntax near 'OFFSET'.
Invalid usage of the option NEXT in the FETCH statement.

如何修改sql server 2008的查询？

还有一个问题.如何编写列出页面的存储过程？这是我的完整代码http://codepaste.net/gq5n6c

Answer 1

对于首先使用Entity Framework,特别是数据库的人来说,如果使用SQL 2012进行开发但部署到早期版本,则会发生此错误.

如果您使用Take ... Skip功能,则会出现此问题,因为SQL 2012有一个新的语法.看到:

修复方法是编辑.edmx文件并将ProviderManifestToken值从2012更改为您的数据库版本,例如2008.

Answer 2

正如在评论中发现的那样,错误的原因是因为SQL Server 2008不支持它.您可以尝试根据SQL Server 2012更改查询.

像这样: -

SELECT column1
FROM   (
          SELECT column1, ROW_NUMBER() OVER (ORDER BY column_id) AS x
          FROM   mytable
       ) AS tbl
WHERE  tbl.x BETWEEN 20 AND 30

在你的代码中: -

SELECT * FROM  
(SELECT ROW_NUMBER() OVER(ORDER BY q.qId) AS rownumber 
FROM tblQuestion AS q 
INNER JOIN tblUser AS u ON q.uId = u.uId 
INNER JOIN tblQuestionCategory AS qcat ON q.qcatId = qcat.qcatId ) as somex 
WHERE  somex.rownumber  BETWEEN 11 AND 20

问题是因为你还没有定义@page.

试试这个(因为你没有提到它是什么@page.我把它作为一些常量或者你可以声明它然后设置它的值): -

declare @page int
set @page = 5  // You may set any value here.

SELECT q.qTitle, q.qDescription, q.qCreatedOn, u.uCode, 
u.uFullname, qcat.qcatTitle, q.qId, q.qStatus 
FROM tblQuestion AS q 
INNER JOIN tblUser AS u ON q.uId = u.uId 
INNER JOIN tblQuestionCategory AS qcat ON q.qcatId = qcat.qcatId 
WHERE (q.qStatus = 1) 
ORDER BY q.qCreatedOn DESC 
OFFSET (@page*10) ROWS
FETCH NEXT 10 ROWS ONLY
