[MSSQL]如何利用SQL CMD來製作前端分頁

方法一:利用Not In和SELECT TOP分页



SELECT TOP 10 *

FROM TestTable
WHERE (ID NOT IN
 (SELECT TOP 20 id
 FROM TestTable
 ORDER BY id))
ORDER BY ID




SELECT TOP 页大小 *
FROM TestTable
WHERE (ID NOT IN
 (SELECT TOP 页大小*页数 id
 FROM 表
 ORDER BY id))
ORDER BY ID




方法二:利用ID大于多少和SELECT TOP分页

SELECT TOP 10 *
FROM TestTable
WHERE (ID >
 (SELECT MAX(id)
 FROM (SELECT TOP 20 id
 FROM TestTable
 ORDER BY id) AS T))
ORDER BY ID


SELECT TOP 页大小 *
FROM TestTable
WHERE (ID >
 (SELECT MAX(id)
 FROM (SELECT TOP 页大小*页数 id
 FROM 表
 ORDER BY id) AS T))
ORDER BY ID




法方三:利用SQL的SP分页

create procedure SqlPager
@sqlstr nvarchar(4000), --查询字符串
@currentpage int, --第N页
@pagesize int --每页行数
as
set nocount on
declare @P1 int, --P1是游标的id
 @rowcount int
exec sp_cursoropen @P1 output,@sqlstr,@scrollopt=1,@ccopt=1,@rowcount=@rowcount output
select ceiling(1.0*@rowcount/@pagesize) as 总页数--,@rowcount as 总行数,@currentpage as 当前页
set @currentpage=(@currentpage-1)*@pagesize+1
exec sp_cursorfetch @P1,16,@currentpage,@pagesize
exec sp_cursorclose @P1
set nocount off



效率以 1>2>3
