表中主键必须为标识列，[ID] int IDENTITY (1,1)//每次自增一
1.分页方案一：(利用Not In和SELECT TOP分页)
语句形式：
复制代码代码如下:
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
2.分页方案二：(利用ID大于多少和SELECT TOP分页）
语句形式：
复制代码代码如下:
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
3.分页方案三：(利用SQL的游标存储过程分页)
复制代码代码如下:
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
4.
复制代码代码如下:
CREATE Procedure FramWorkPage
@TableName varchar(50), --表名
@Fields varchar(5000) = '*', --字段名(全部字段为*)
@OrderField varchar(5000), --排序字段(必须!支持多字段)
@sqlWhere varchar(5000) = Null,--条件语句(不用加where)
@pageSize int, --每页多少条记录
@pageIndex int = 1 , --指定当前为第几页
@TotalPage int output, --返回条数
@OrderType bit -- 设置排序类型,1 升序 0 值则降序
as
begin
declare @strOrder varchar(400) -- 排序类型
Begin Tran --开始事务
Declare @sql nvarchar(4000);
Declare @totalRecord int;
--计算总记录数
if (@SqlWhere ='''' or @SqlWhere='' or @sqlWhere is NULL)
set @sql = 'select @totalRecord = count(*) from ' + @TableName
else
set @sql = 'select @totalRecord = count(*) from ' + @TableName + ' where ' + @sqlWhere
EXEC sp_executesql @sql,N'@totalRecord int OUTPUT',@totalRecord OUTPUT--计算总记录数
--计算总页数
select @TotalPage=@totalRecord --CEILING((@totalRecord+0.0)/@PageSize)
if @OrderType = 0
begin
set @strOrder = ' order by [' + @OrderField +'] desc'
--如果@OrderType是0，就执行降序，这句很重要！
end
else
begin
set @strOrder = ' order by [' + @OrderField +'] asc'
end
if (@SqlWhere ='''' or @SqlWhere='' or @sqlWhere is NULL)
set @sql = 'Select * FROM (select ROW_NUMBER() Over( '+@strOrder+' ) as rowId,' + @Fields + ' from ' + @TableName
else
set @sql = 'Select * FROM (select ROW_NUMBER() Over( '+@strOrder+' ) as rowId,' + @Fields + ' from ' + @TableName + ' where ' + @SqlWhere
--处理页数超出范围情况
if @PageIndex<=0
Set @pageIndex = 1
if @pageIndex>@TotalPage
Set @pageIndex = @TotalPage
--处理开始点和结束点
Declare @StartRecord int
Declare @EndRecord int
set @StartRecord = (@pageIndex-1)*@PageSize + 1
set @EndRecord = @StartRecord + @pageSize - 1
if @OrderType = 0
begin
set @strOrder = ' order by rowid desc'
--如果@OrderType是0，就执行降序，这句很重要！
end
else
begin
set @strOrder = ' order by rowid asc'
end
--继续合成sql语句
set @Sql = @Sql + ') as ' + @TableName + ' where rowId between ' + Convert(varchar(50),@StartRecord) + ' and ' + Convert(varchar(50),@EndRecord) + ' '+@strOrder
-- print @sql
Exec(@Sql)
---------------------------------------------------
If @@Error <> 0
Begin
RollBack Tran
Return -1
End
Else
Begin
Commit Tran
Return @totalRecord ---返回记录总数
End
end
通过上面这些东西的学习。我想一定可以找到一种满意的答案。。。
