分页存储过程

在前辈们的基础上，修改了几个地方，用起来感觉还挺好的一个分页存储过程：

USE [Information]
GO


/****** Object:  StoredProcedure [dbo].[UP_GetRecordByPage]    Script Date: 12/19/2011 19:13:25 ******/
SET ANSI_NULLS ON
GO


SET QUOTED_IDENTIFIER OFF
GO








CREATE  PROCEDURE GetRecordByPage
@tblName varchar(255), -- 表名
@fldName varchar(255), -- 主键字段名
@PageSize int , -- 页尺寸
@PageIndex int , -- 页码
@IsReCount bit, -- 返回记录总数, 非 0 值则返回
@OrderType bit, -- 设置排序类型, 非 0 值则降序
@strWhere varchar(1000) = '' -- 查询条件 (注意: 不要加 where)
AS
declare @strSQL varchar(6000) -- 主语句
declare @strTmp varchar(2000) -- 临时变量(查询条件过长时可能会出错，可修改100为1000)
declare @strOrder varchar(400) -- 排序类型
if @OrderType != 0
begin
set @strTmp = '<(select min'
set @strOrder = ' order by [' + @fldName +'] desc'
end
else
begin
set @strTmp = '>(select max'
set @strOrder = ' order by [' + @fldName +'] asc'
end
set @strSQL = 'select top ' + str(@PageSize) + ' * from ['

+ @fldName + '] from [' + @tblName + ']' + @strOrder + ') as tblTmp)'
+ @strOrder
if @strWhere != ''
set @strSQL = 'select top ' + str(@PageSize) + ' * from ['

if @PageIndex = 1
begin

if @strWhere != ''
set @strTmp = ' where ' + @strWhere
set @strSQL = 'select top ' + str(@PageSize) + ' * from ['

end
if @IsReCount != 0 
begin

begin
set @strSQL += ' select count(0) as Total from [' + @tblName + ']'
end 
else

end
end
exec (@strSQL)
go
