sql server 2005的分页存储过程分3个版本，一个是没有优化过的，一个是优化过的，最后一个支持join的，sql server 2000的分页存储过程，也可以运行在sql server 2005上，但是性能没有sql server 2005的版本好。
在最后 我还附带了一个二分法的分页存储过程，也很好用的说哈~~
1.SqlServer 2005：
CREATE proc [dbo].[up_Page2005]
@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 –返回总页数
as
begin
Begin Tran –开始事务
Declare @sql nvarchar(4000);
Declare @totalRecord int;
–计算总记录数
if (@SqlWhere=” or @sqlWhere=NULL)
set @sql = ‘select @totalRecord = count() from ‘ + @TableName
else
set @sql = ‘select @totalRecord = count() from ‘ + @TableName + ‘ with(nolock) 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=CEILING((@totalRecord+0.0)/@PageSize)
if (@SqlWhere=” or @sqlWhere=NULL)
set @sql = ‘Select FROM (select ROW_NUMBER() Over(order by ‘ + @OrderField + ‘) as rowId,’ + @Fields + ‘ from ‘ + @TableName
else
set @sql = ‘Select FROM (select ROW_NUMBER() Over(order by ‘ + @OrderField + ‘) as rowId,’ + @Fields + ‘ from ‘ + @TableName + ‘ with(nolock) 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
–继续合成sql语句
set @Sql = @Sql + ‘) as t where rowId between ‘ + Convert(varchar(50),@StartRecord) + ‘ and ‘ + Convert(varchar(50),@EndRecord)
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
2.Sql Server 2005:
Begin Tran –开始事务
Declare @sql nvarchar(4000);
if @totalRecord<=0 begin
–计算总记录数
if (@SqlWhere='' or @sqlWhere=NULL)
set @sql = 'select @totalRecord = count(*) from ' + @TableName
else
set @sql = 'select @totalRecord = count(*) from ' + @TableName + ' with(nolock) where ' + @sqlWhere
EXEC sp_executesql @sql,@totalRecord OUTPUT--计算总记录数end
–计算总页数
select @TotalPage=CEILING((@totalRecord+0.0)/@PageSize)
if (@SqlWhere=” or @sqlWhere=NULL)
set @sql = ‘Select * FROM (select ROW_NUMBER() Over(order by ‘ + @OrderField + ‘) as rowId,@EndRecord)
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
GO
3.Sql Server 2005:
Declare @sql nvarchar(4000);
if @totalRecord<=0 begin
–计算总记录数
if (@SqlWhere='' or @sqlWhere=NULL)
set @sql = 'select @totalRecord = count(*) from ' + @TableName
else
set @sql = 'select @totalRecord = count(*) from ' + @TableName + ' where ' + @sqlWhere
EXEC sp_executesql @sql,' + @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
–继续合成sql语句
set @Sql = @Sql + ‘) as t where rowId between ‘ + Convert(varchar(50),@EndRecord)
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
4.Sql Server 2000:
@RecordCount int output,@ReturnCount bit,@QueryStr nvarchar(1000)=’table1′,–表名、视图名、查询语句
@PageSize int=20,–每页的大小(行数)
@PageCurrent int=2,–要显示的页 从0开始
@FdShow nvarchar (2000)=’*’,–要显示的字段列表
@IdentityStr nvarchar (100)=’id’,–主键
@WhereStr nvarchar (2000)=’1=1′,@FdOrder nvarchar(100)=’desc’ –排序 只能取desc或者asc
as
set nocount on
declare
@sql nvarchar(2000)
if @WhereStr = ” begin
set @WhereStr = ‘1=1’
end
if @ReturnCount=1 begin
declare @tsql nvarchar(200)
set @tsql=N’select @RecordCount = count(*) from ‘ + @QueryStr + ‘ where ‘ + @WhereStr
exec sp_executesql @tsql,N’@RecordCount int output’,@RecordCount output
end
if @PageCurrent = 0 begin
set @sql = ‘select top ‘ + cast(@PageSize as nvarchar(3)) + ‘ ‘ + @FdShow + ‘ from ‘ + @QueryStr + ‘ where ‘ + @WhereStr + ‘ order by ‘ + @IdentityStr + ‘ ‘ + @FdOrder
end
else begin
if upper(@FdOrder) = ‘DESC’ begin
set @sql = ‘select top ‘ + cast(@PageSize as nvarchar(3)) + ‘ ‘ + @FdShow + ‘ from ‘ + @QueryStr + ‘ where ‘ + @WhereStr + ‘ and ‘ + @IdentityStr + ‘< ( select min(‘ + @IdentityStr + ‘) from (select top ‘ + cast(@PageSize@PageCurrent as nvarchar(10)) + ‘ ‘ + @IdentityStr + ‘ from ‘ + @QueryStr + ‘ where ‘ + @WhereStr + ‘ order by ‘ + @IdentityStr + ‘ desc) as t) order by ‘ + @IdentityStr + ‘ desc’
end
else begin
set @sql = ‘select top ‘ + cast(@PageSize as nvarchar(3)) + ‘ ‘ + @FdShow + ‘ from ‘ + @QueryStr + ‘ where ‘ + @WhereStr + ‘ and ‘ + @IdentityStr + ‘> ( select max(‘ + @IdentityStr + ‘) from (select top ‘ + cast(@PageSize@PageCurrent as nvarchar(10)) + ‘ ‘ + @IdentityStr + ‘ from ‘ + @QueryStr + ‘ where ‘ + @WhereStr + ‘ order by ‘ + @IdentityStr + ‘ asc) as t) order by ‘ + @IdentityStr + ‘ asc’
end
end
–print @sql
execute(@sql)
二分分页过程：
alter PROCEDURE proc_paged_2part_selectMax
(
@tblName nvarchar(200),—-要显示的表或多个表的连接
@fldName nvarchar(500) = ‘*’,—-要显示的字段列表
@pageSize int = 10,—-每页显示的记录个数
@page int = 1,—-要显示那一页的记录
@fldSort nvarchar(200) = null,—-排序字段列表或条件
@Sort bit = 0,—-排序方法，0为升序，1为降序(如果是多字段排列Sort指代最后一个排序字段的排列顺序(最后一个排序字段不加排序标记)–程序传参如：’ SortA Asc,SortB Desc,SortC ‘)
@strCondition nvarchar(1000) = null,—-查询条件,不需where
@ID nvarchar(150),—-主表的主键
@Dist bit = 0,—-是否添加查询字段的 DISTINCT 默认0不添加/1添加
@pageCount int = 1 output,—-查询结果分页后的总页数
@Counts int = 1 output —-查询到的记录数
)
AS
SET NOCOUNT ON
Declare @sqlTmp nvarchar(1000) —-存放动态生成的SQL语句
Declare @strTmp nvarchar(1000) —-存放取得查询结果总数的查询语句
Declare @strID nvarchar(1000) —-存放取得查询开头或结尾ID的查询语句
Declare @strSortType nvarchar(10) —-数据排序规则A
Declare @strFSortType nvarchar(10) —-数据排序规则B
Declare @SqlSelect nvarchar(50) —-对含有DISTINCT的查询进行SQL构造
Declare @SqlCounts nvarchar(50) —-对含有DISTINCT的总数查询进行SQL构造
declare @timediff datetime –耗时测试时间差
select @timediff=getdate()
