oracle，sqlserver分页查询sql语句

Oracle：

方法一：
SELECT * FROM

(

SELECT A.*, ROWNUM RN

FROM (SELECT * FROM TABLE_NAME) A

WHERE ROWNUM <= 40

)

WHERE RN >= 21；

方法二：
SELECT * FROM

(

SELECT A.*, ROWNUM RN

FROM (SELECT * FROM TABLE_NAME) A

)

WHERE RN between 21 and 40

公认第二种方法效率没有第一种高。原因是第二种要把子查询执行完，而第一种方法子查询执行到Rownum=40后就结束了。

MySQL:

SELECT * FROM TABLE_NAME LIMIT 10, 20

表示从第11条数据开始取20条数据返回，limit后的2个参数含义为：起点和步长，即从那条数据开始，取多少条数据，再如取前20条数据：SELECT * FROM TABLE_NAME LIMIT 0, 20

SQL Server2000：

SELECT TOP @pagesize * FROM TABLE_NAME WHERE id not in (SELECT TOP @pagesize*(@page-1) id FROM TABLE_NAME ORDER BY id) ORDER BY id

SQL Server 2005：

方法一：

SELECT ...

FROM
(

SELECT ROW_NUMBER() OVER (ORDER BY ID asc) AS RowNum, ......

FROM TABLE_NAME

) AS T

WHERE T.RowNum> 10 and T.RowNum<= 20

方法二：

WITH DataList AS

(

SELECT ROW_NUMBER() OVER (ORDER BY O.ID DESC)AS RowNum, ......

FROM .....

WHERE ......
)

SELECT ......

FROM DataList

WHERE RowNum BETWEEN 10 AND 20
