在SQL Server 2000、2005、2008、2012中分页结果的最佳方法(性能方面)是什么?如果你还想获得结果的总数(在分页之前)?

create PROCEDURE SP_Company_List (@pagesize int= -1,@pageindex int= 0) 选择Id, NameEn从公司订单的Id ASC OFFSET (@pageindex-1)* @pagesize ROWS FETCH NEXt @pagesize ROWS ONLY END GO 声明@return_value int EXEC @return_value = [dbo]。[SP_Company_List] @pagesize = 1, > @pageindex = 2 SELECT 'Return Value' = @return_value 去

MSDN: ROW_NUMBER (Transact-SQL)

返回结果集中分区内某一行的顺序编号,每个分区中的第一行从1开始。 下面的示例按照OrderDate的顺序返回数字为50到60的行。

WITH OrderedOrders AS
(
    SELECT
        ROW_NUMBER() OVER(ORDER BY FirstName DESC) AS RowNumber, 
        FirstName, LastName, ROUND(SalesYTD,2,1) AS "Sales YTD"
    FROM [dbo].[vSalesPerson]
) 
SELECT RowNumber, 
    FirstName, LastName, Sales YTD 
FROM OrderedOrders 
WHERE RowNumber > 50 AND RowNumber < 60;
  RowNumber FirstName    LastName               SalesYTD

在SQL Server 2012中,我们可以使用OFFSET和FETCH NEXT子句来实现分页。

试试这个,SQL Server:

In the SQL Server 2012 a new feature was added in the ORDER BY clause, to query optimization of a set data, making work easier with data paging for anyone who writes in T-SQL as well for the entire Execution Plan in SQL Server. Below the T-SQL script with the same logic used in the previous example. --CREATING A PAGING WITH OFFSET and FETCH clauses IN "SQL SERVER 2012" DECLARE @PageNumber AS INT, @RowspPage AS INT SET @PageNumber = 2 SET @RowspPage = 10 SELECT ID_EXAMPLE, NM_EXAMPLE, DT_CREATE FROM TB_EXAMPLE ORDER BY ID_EXAMPLE OFFSET ((@PageNumber - 1) * @RowspPage) ROWS FETCH NEXT @RowspPage ROWS ONLY;

使用SQL Server对查询进行分页

这个位使您能够使用SQL Server和新版本的MySQL进行分页,并携带每行中的总行数。 使用您的类推键来计数唯一行数。

WITH T AS
(  
  SELECT TABLE_ID, ROW_NUMBER() OVER (ORDER BY TABLE_ID) AS RN
  , (SELECT COUNT(TABLE_ID) FROM TABLE) AS TOTAL 
  FROM TABLE (NOLOCK)
)

SELECT T2.FIELD1, T2.FIELD2, T2.FIELD3, T.TOTAL 
FROM TABLE T2 (NOLOCK)
INNER JOIN T ON T2.TABLE_ID=T.TABLE_ID
WHERE T.RN >= 100
AND T.RN < 200

好吧,我已经在我的SQL 2000数据库中使用了以下示例查询,它也适用于SQL 2005。它通过使用多个列来动态排序。 我告诉你……这是强大的:)

    ALTER PROCEDURE [dbo].[RE_ListingReports_SelectSummary] 

@CompanyID  int,
@pageNumber     int,
@pageSize   int, 
@sort       varchar(200)
AS

DECLARE @sql nvarchar(4000)
DECLARE @strPageSize nvarchar(20)
DECLARE @strSkippedRows nvarchar(20)
DECLARE @strFields nvarchar(4000)
DECLARE @strFilter nvarchar(4000)
DECLARE @sortBy nvarchar(4000)
DECLARE @strFrom nvarchar(4000)
DECLARE @strID nvarchar(100)

If(@pageNumber < 0)
  SET @pageNumber = 1
SET @strPageSize = CAST(@pageSize AS varchar(20)) 
SET @strSkippedRows = CAST(((@pageNumber - 1) * @pageSize) AS varchar(20))-- For    example if pageNumber is 5  pageSize is 10, then SkippedRows = 40.
SET @strID = 'ListingDbID'
SET @strFields = 'ListingDbID,
ListingID,  
[ExtraRoom]
'
SET @strFrom = ' vwListingSummary '

SET @strFilter = ' WHERE
        CompanyID = ' + CAST(@CompanyID As varchar(20)) 
End
SET @sortBy = ''
if(len(ltrim(rtrim(@sort))) > 0)
SET @sortBy = ' Order By ' + @sort

-- Total Rows Count

SET @sql =  'SELECT Count(' + @strID + ')  FROM ' + @strFROM + @strFilter
EXEC sp_executesql @sql

--// This technique is used in a Single Table pagination
SET @sql = 'SELECT ' + @strFields + ' FROM ' + @strFROM +
    ' WHERE ' + @strID +  ' IN ' + 
   '  (SELECT TOP ' + @strPageSize + ' ' + @strID + ' FROM ' + @strFROM + @strFilter + 
             ' AND  ' + @strID + ' NOT IN ' + '
          (SELECT TOP ' + @strSkippedRows + ' ' + @strID + ' FROM ' + @strFROM + @strFilter + @SortBy + ') ' 
   + @SortBy + ') ' + @SortBy
Print @sql 
EXEC sp_executesql @sql

最好的部分是sp_executesql缓存以后的调用,只要您传递相同的参数,即生成相同的sql文本。

试试这个方法:

SELECT TOP @offset a.*
FROM (select top @limit b.*, COUNT(*) OVER() totalrows 
        from TABLENAME b order by id asc) a
ORDER BY id desc;
