在 SQL 服务器中对结果进行分页的最佳方法是什么

Question

What is the best way (performance wise) to paginate results in SQL Server 2000, 2005, 2008, 2012 if you also want to get the total number of results (before paginating)?

Answer 1

Finally, Microsoft SQL Server 2012 was released, I really like its simplicity for a pagination, you don't have to use complex queries like answered here.

For getting the next 10 rows just run this query:

SELECT * FROM TableName ORDER BY id OFFSET 10 ROWS FETCH NEXT 10 ROWS ONLY;

https://docs.microsoft.com/en-us/sql/t-sql/queries/select-order-by-clause-transact-sql#using-offset-and-fetch-to-limit-the-rows-returned

Key points to consider when using it:

• ORDER BY is mandatory to use OFFSET ... FETCH clause.
• OFFSET clause is mandatory with FETCH . You cannot use ORDER BY ... FETCH .
• TOP cannot be combined with OFFSET and FETCH in the same query expression.

Answer 2

Getting the total number of results and paginating are two different operations. For the sake of this example, let's assume that the query you're dealing with is

SELECT * FROM Orders WHERE OrderDate >= '1980-01-01' ORDER BY OrderDate

In this case, you would determine the total number of results using:

SELECT COUNT(*) FROM Orders WHERE OrderDate >= '1980-01-01'

...which may seem inefficient, but is actually pretty performant, assuming all indexes etc. are properly set up.

Next, to get actual results back in a paged fashion, the following query would be most efficient:

SELECT  *
FROM    ( SELECT    ROW_NUMBER() OVER ( ORDER BY OrderDate ) AS RowNum, *
          FROM      Orders
          WHERE     OrderDate >= '1980-01-01'
        ) AS RowConstrainedResult
WHERE   RowNum >= 1
    AND RowNum < 20
ORDER BY RowNum

This will return rows 1-19 of the original query. The cool thing here, especially for web apps, is that you don't have to keep any state, except the row numbers to be returned.

Answer 3

Incredibly, no other answer has mentioned the fastest way to do pagination in all SQL Server versions. Offsets can be terribly slow for large page numbers as is benchmarked here . There is an entirely different, much faster way to perform pagination in SQL. This is often called the "seek method" or "keyset pagination" as described in this blog post here .

SELECT TOP 10 first_name, last_name, score, COUNT(*) OVER()
FROM players
WHERE (score < @previousScore)
   OR (score = @previousScore AND player_id < @previousPlayerId)
ORDER BY score DESC, player_id DESC

The "seek predicate"

The @previousScore and @previousPlayerId values are the respective values of the last record from the previous page. This allows you to fetch the "next" page. If the ORDER BY direction is ASC , simply use > instead.

With the above method, you cannot immediately jump to page 4 without having first fetched the previous 40 records. But often, you do not want to jump that far anyway. Instead, you get a much faster query that might be able to fetch data in constant time, depending on your indexing. Plus, your pages remain "stable", no matter if the underlying data changes (eg on page 1, while you're on page 4).

This is the best way to implement pagination when lazy loading more data in web applications, for instance.

Note, the "seek method" is also called keyset pagination .

Total records before pagination

The COUNT(*) OVER() window function will help you count the number of total records "before pagination". If you're using SQL Server 2000, you will have to resort to two queries for the COUNT(*) .

Answer 4

From SQL Server 2012, we can use OFFSET and FETCH NEXT Clause to achieve the pagination.

Try this, for 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;

Answer 5

MSDN: ROW_NUMBER (Transact-SQL)

Returns the sequential number of a row within a partition of a result set, starting at 1 for the first row in each partition.

The following example returns rows with numbers 50 to 60 inclusive in the order of the OrderDate.

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

Answer 6

There is a good overview of different paging techniques at http://www.codeproject.com/KB/aspnet/PagingLarge.aspx

I've used ROWCOUNT method quite often mostly with SQL Server 2000 (will work with 2005 & 2008 too, just measure performance compared to ROW_NUMBER), it's lightning fast, but you need to make sure that the sorted column(s) have (mostly) unique values.

Answer 7

For SQL Server 2000 you can simulate ROW_NUMBER() using a table variable with an IDENTITY column:

DECLARE @pageNo int -- 1 based
DECLARE @pageSize int
SET @pageNo = 51
SET @pageSize = 20

DECLARE @firstRecord int
DECLARE @lastRecord int
SET @firstRecord = (@pageNo - 1) * @pageSize + 1 -- 1001
SET @lastRecord = @firstRecord + @pageSize - 1   -- 1020

DECLARE @orderedKeys TABLE (
  rownum int IDENTITY NOT NULL PRIMARY KEY CLUSTERED,
  TableKey int NOT NULL
)

SET ROWCOUNT @lastRecord
INSERT INTO @orderedKeys (TableKey) SELECT ID FROM Orders WHERE OrderDate >= '1980-01-01' ORDER BY OrderDate

SET ROWCOUNT 0

SELECT t.*
FROM Orders t
  INNER JOIN @orderedKeys o ON o.TableKey = t.ID
WHERE o.rownum >= @firstRecord
ORDER BY o.rownum

This approach can be extended to tables with multi-column keys, and it doesn't incur the performance overhead of using OR (which skips index usage). The downside is the amount of temporary space used up if the data set is very large and one is near the last page. I did not test cursor performance in that case, but it might be better.

Note that this approach could be optimized for the first page of data. Also, ROWCOUNT was used since TOP does not accept a variable in SQL Server 2000.

Answer 8

The best way for paging in sql server 2012 is by using offset and fetch next in a stored procedure. OFFSET Keyword - If we use offset with the order by clause then the query will skip the number of records we specified in OFFSET n Rows.

FETCH NEXT Keywords - When we use Fetch Next with an order by clause only it will returns the no of rows you want to display in paging, without Offset then SQL will generate an error. here is the example given below.

create procedure sp_paging
(
 @pageno as int,
 @records as int
)
as
begin
declare @offsetcount as int
set @offsetcount=(@pageno-1)*@records
select id,bs,variable from salary order by id offset @offsetcount rows fetch Next @records rows only
end

you can execute it as follow.

exec sp_paging 2,3

Answer 9

Try this approach:

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

Answer 10

These are my solutions for paging the result of query in SQL server side. these approaches are different between SQL Server 2008 and 2012. Also, I have added the concept of filtering and order by with one column. It is very efficient when you are paging and filtering and ordering in your Gridview.

Before testing, you have to create one sample table and insert some row in this table : (In real world you have to change Where clause considering your table fields and maybe you have some join and subquery in main part of select)

Create Table VLT
(
    ID int IDentity(1,1),
    Name nvarchar(50),
    Tel Varchar(20)
)
GO


Insert INTO VLT
VALUES
    ('NAME' + Convert(varchar(10),@@identity),'FAMIL' + Convert(varchar(10),@@identity))
GO 500000

In all of these sample, I want to query 200 rows per page and I am fetching the row for page number 1200.

In SQL server 2008, you can use the CTE concept. Because of that, I have written two type of query for SQL server 2008+

-- SQL Server 2008+

DECLARE @PageNumber Int = 1200
DECLARE @PageSize INT = 200
DECLARE @SortByField int = 1 --The field used for sort by
DECLARE @SortOrder nvarchar(255) = 'ASC' --ASC or DESC
DECLARE @FilterType nvarchar(255) = 'None' --The filter type, as defined on the client side (None/Contain/NotContain/Match/NotMatch/True/False/)
DECLARE @FilterValue nvarchar(255) = '' --The value the user gave for the filter
DECLARE @FilterColumn int = 1 --The column to wich the filter is applied, represents the column number like when we send the information.

SELECT 
  Data.ID,
  Data.Name,

FROM
  (  
    SELECT

                CASE WHEN @SortByField = 1 AND @SortOrder = 'ASC'
                      THEN VLT.ID END ASC,
                CASE WHEN @SortByField = 1 AND @SortOrder = 'DESC'
                      THEN VLT.ID END DESC,
                CASE WHEN @SortByField = 2 AND @SortOrder = 'ASC'
                      THEN VLT.Name END ASC,
                CASE WHEN @SortByField = 2 AND @SortOrder = 'DESC'
                      THEN VLT.Name END ASC,
                CASE WHEN @SortByField = 3 AND @SortOrder = 'ASC'
                      THEN VLT.Tel END ASC,

                @FilterValue = ''
               ) THEN 1
          WHEN @FilterType = 'NotContain' AND @FilterColumn = 1
            AND ( -- In this case, when the filter value is empty, we want to show everything.
                VLT.ID NOT LIKE '%' + @FilterValue + '%'

从 2012 年开始，我们可以使用OFFSET 10 ROWS FETCH NEXT 10 ROWS ONLY

Answer 12

Use case wise the following seem to be easy to use and fast. Just set the page number.

use AdventureWorks
DECLARE @RowsPerPage INT = 10, @PageNumber INT = 6;
with result as(
SELECT SalesOrderDetailID, SalesOrderID, ProductID,
ROW_NUMBER() OVER (ORDER BY SalesOrderDetailID) AS RowNum
FROM Sales.SalesOrderDetail
where 1=1
)
select SalesOrderDetailID, SalesOrderID, ProductID from result
WHERE result.RowNum BETWEEN ((@PageNumber-1)*@RowsPerPage)+1
AND @RowsPerPage*(@PageNumber)

also without CTE

use AdventureWorks
DECLARE @RowsPerPage INT = 10, @PageNumber INT = 6
SELECT SalesOrderDetailID, SalesOrderID, ProductID
FROM (
SELECT SalesOrderDetailID, SalesOrderID, ProductID,
ROW_NUMBER() OVER (ORDER BY SalesOrderDetailID) AS RowNum
FROM Sales.SalesOrderDetail
where 1=1
 ) AS SOD
WHERE SOD.RowNum BETWEEN ((@PageNumber-1)*@RowsPerPage)+1
AND @RowsPerPage*(@PageNumber)

Answer 13

This is a duplicate of the 2012 old SO question: efficient way to implement paging

FROM [TableX] ORDER BY [FieldX] OFFSET 500 ROWS FETCH NEXT 100 ROWS ONLY

Here the topic is discussed in greater details, and with alternate approaches.

   CREATE view vw_sppb_part_listsource as 
    select row_number() over (partition by sppb_part.init_id order by sppb_part.sppb_part_id asc ) as idx, * from (
      select 
          part.SPPB_PART_ID
          , 0 as is_rev
          , part.part_number 
          , part.init_id 
      from t_sppb_init_part part 
      left join t_sppb_init_partrev prev on ( part.SPPB_PART_ID = prev.SPPB_PART_ID )
      where prev.SPPB_PART_ID is null 
      union 
      select 
          part.SPPB_PART_ID
          , 1 as is_rev
          , prev.part_number 
          , part.init_id 
      from t_sppb_init_part part 
      inner join t_sppb_init_partrev prev on ( part.SPPB_PART_ID = prev.SPPB_PART_ID )
    ) sppb_part

will restart idx when it comes to different init_id

Answer 15

For the ROW_NUMBER technique, if you do not have a sorting column to use, you can use the CURRENT_TIMESTAMP as follows:

SELECT TOP 20 
    col1,
    col2,
    col3,
    col4
FROM (
    SELECT 
         tbl.col1 AS col1
        ,tbl.col2 AS col2
        ,tbl.col3 AS col3
        ,tbl.col4 AS col4
        ,ROW_NUMBER() OVER (
            ORDER BY CURRENT_TIMESTAMP
            ) AS sort_row
    FROM dbo.MyTable tbl
    ) AS query
WHERE query.sort_row > 10
ORDER BY query.sort_row

This has worked well for me for searches over table sizes of even up to 700,000.

This fetches records 11 to 30.

Answer 17

This bit gives you ability to paginate using SQL Server, and newer versions of MySQL and carries the total number of rows in every row. Uses your pimary key to count number of unique rows.

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

Answer 18

We can achieve Pagination in SQL by using LIMIT

SELECT * FROM table_name ORDER BY column_name LIMIT <start_index>,<end_index>

we can pass 1 as id for page 1, 2 as id for page 2 and so on, let us consider page number as id

n = numberOfRecordsInEachPage  
start_index = id * n - n  
end_index = n

General Query

SELECT * FROM table_name ORDER BY column_name LIMIT <skip_rows>,<number_of_rows_to_display_after_skipping>

Answer 19

Well I have used the following sample query in my SQL 2000 database, it works well for SQL 2005 too. The power it gives you is dynamically order by using multiple columns. I tell you ... this is powerful :)

    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

The best part is sp_executesql caches later calls, provided you pass same parameters ie generate same sql text.

Answer 20

You didn't specify the language nor which driver you are using. Therefore I'm describing it abstractly.

• Create a scrollable resultset / dataset. This required a primary on the table(s)
• jump to the end
• request the row count
• jump to the start of the page
• scroll through the rows until the end of the page
