SQL Server 2005 引入了 ROW_NUMBER()来提供一种容易的分页方式。 SQL Server 2012 添加了另外一种更简单高效的分页方式。

1. /*
2. 执行脚本去创建这个表并插入数据。
3. */
4. IF OBJECT_ID('Customers','U') IS NOT NULL
5. DROP TABLE Customers
6. CREATE TABLE Customers (
7. CustomerID INT,
8. CustomerNumber CHAR(4),
9. CustomerName VARCHAR(50),
10. CustomerCity VARCHAR(20) )
11. GO
12. INSERT INTO Customers (
13. CustomerID, CustomerNumber, CustomerName, CustomerCity
14. )
15. SELECT
16. Number,
17. REPLACE(STR(Number, 4), ' ', '0'),
18. 'Customer ' + STR(number,6),
19. CHAR(65 + (number % 26)) + '-City'
20. FROM master..spt_values WHERE type = 'p'
21. AND number BETWEEN 0 AND 999
22. /*
23. 用ROW_NUMBER()的分页示例- SQL Server 2005/2008 版本。
24. */
25. DECLARE @page INT, @size INT
26. SELECT @page = 3, @size = 10
27. ;WITH cte AS (
28. SELECT TOP (@page * @size)
29. CustomerID,
30. CustomerName,
31. CustomerCity,
32. ROW_NUMBER() OVER(ORDER BY CustomerName ) AS Seq,
33. COUNT(*) OVER(PARTITION BY '') AS Total
34. FROM Customers
35. WHERE CustomerCity IN ('A-City','B-City')
36. ORDER BY CustomerName ASC
37. )
38. SELECT
39. *
40. FROM cte
41. WHERE seq BETWEEN (@page - 1 ) * @size + 1 AND @page * @size
42. ORDER BY seq
43. /*
44. SQL Server 2012中新添加的分页示例
45. */
46. DECLARE @page INT, @size INT
47. SELECT @page = 3, @size = 10
48. SELECT
49. *,
50. COUNT(*) OVER(PARTITION BY '') AS Total
51. FROM Customers
52. WHERE CustomerCity IN ('A-City','B-City')
53. ORDER BY CustomerID
54. OFFSET (@page -1) * @size ROWS
55. FETCH NEXT @size ROWS ONLY;
56. /*
57. 同时执行这两个版本，打开执行计划，你可以注意到在这个例子中显著的性能差异。
