SQL分页语句三方案

方法一：

SELECT TOP 页大小 *
FROM table1
WHERE id NOT IN
          (
          SELECT TOP 页大小*(页数-1) id FROM table1 ORDER BY id
          )
ORDER BY id

方法二：

SELECT TOP 页大小 *
FROM table1
WHERE id >
          (
          SELECT ISNULL(MAX(id),0)
          FROM
                (
                SELECT TOP 页大小*(页数-1) id FROM table1 ORDER BY id
                ) A
          )
ORDER BY id

方法二倒序：

SELECT TOP 页大小 *
FROM table1
WHERE ID <=
    (
    SELECT ISNULL(MIN(ID),(SELECT MAX(ID) FROM table1 ))
    FROM
        (
        SELECT TOP (页大小*(页数-1)) ID FROM tbl_files ORDER BY ID DESC
        ) A
    )
ORDER BY ID DESC

方法三：

SELECT TOP 页大小 *
FROM
        (
        SELECT ROW_NUMBER() OVER (ORDER BY id) AS RowNumber,* FROM table1
        ) A
WHERE RowNumber > 页大小*(页数-1)

分页方案二：(利用ID大于多少和SELECT TOP分页）效率最高，需要拼接SQL语句
分页方案一：(利用Not In和SELECT TOP分页) 效率次之，需要拼接SQL语句
分页方案三：(利用SQL的游标存储过程分页) 效率最差，但是最为通用

2.几种典型的分页sql，下面例子是每页50条，198*50=9900，取第199页数据。

 1 1:row_number()  over()
 2 select  top 50  * from (
 3 select Row_Number() over(order by id) as rownumber ,* from table)a
 4 where  rownumber >9900
 5 
 6 select  * from (
 7 select row_number() over(order by id)as rownumber,*from table)a
 8 where rownumber >9000  adn rownuber<9951
 9 
10 2 not in 
11 
12 select top 50 * from  table
13 where id not in (select top 9900  id  from table  order by id)
14 order by id
