SqlServer 2000、2005分页存储过程整理

发布时间：2020-12-12 09:20:48 所属栏目：MsSql教程 来源：网络整理
导读：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，

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:

-- Description: -- ============================================= CREATE PROCEDURE [dbo].[up_Page2005V2] @TableName varchar(50),--指定当前为第几页 @totalRecord int = 0,@TotalPage int output --返回总页数 AS BEGIN

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:

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 + ' 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:

CREATE proc [dbo].
@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()

if @Dist = 0
begin
set @SqlSelect = 'select '

end
else
