SQL 通用分页 高手请帮忙修正
CREATE PROCEDURE pagination3
@tblName varchar(255), -- 表名
@strGetFields varchar(1000) = ' '* ' ', -- 需要返回的列
@fldName varchar(255)= ' ' ' ', -- 排序的字段名
@PageSize int = 10, -- 页尺寸
@PageIndex int = 1, -- 页码
@doCount bit = 0, -- 返回记录总数, 非 0 值则返回
@OrderType bit = 0, -- 设置排序类型, 非 0 值则降序
@strWhere varchar(1500) = ' ' ' ' -- 查询条件 (注意: 不要加 where)
AS
declare @strSQL varchar(5000) -- 主语句
declare @strTmp varchar(110) -- 临时变量
declare @strOrder varchar(400) -- 排序类型
if @doCount != 0
begin
if @strWhere != ' ' ' '
set @strSQL = "select count(*) as Total from [ " + @tblName + "] where "+@strWhere
else
set @strSQL = "select count(*) as Total from [ " + @tblName + "] "
end 以上代码的意思是如果@doCount传递过来的不是0,就执行总数统计。以下的所有代码都是@doCount为0的情况:
else
begin
if @OrderType != 0
begin
set @strTmp = " <(select min "
set @strOrder = " order by [ " + @fldName + "] desc "如果@OrderType不是0,就执行降序,这句很重要!
end
else
begin
set @strTmp = "> (select max "
set @strOrder = " order by [ " + @fldName + "] asc "
end
if @PageIndex = 1
begin
if @strWhere != ' ' ' '
set @strSQL = "select top " + str(@PageSize) + " "+@strGetFields+ "
from [ " + @tblName + "] where " + @strWhere + " " + @strOrder
else
set @strSQL = "select top " + str(@PageSize) + " "+@strGetFields+ "
from [ "+ @tblName + "] "+ @strOrder如果是第一页就执行以上代码,这样会加快执行速度
end
else
begin以下代码赋予了@strSQL以真正执行的SQL代码
set @strSQL = "select top " + str(@PageSize) + " "+@strGetFields+ " from [ "
+ @tblName + "] where [ " + @fldName + "] " + @strTmp + "([ "+ @fldName + "])
from (select top " + str((@PageIndex-1)*@PageSize) + " [ "+ @fldName + "]
from [ " + @tblName + "] " + @strOrder + ") as tblTmp) "+ @strOrder
if @strWhere != ' ' ' '
set @strSQL = "select top " + str(@PageSize) + " "+@strGetFields+ " from [ "
+ @tblName + "] where [ " + @fldName + "] " + @strTmp + "([ "
+ @fldName + "]) from (select top " + str((@PageIndex-1)*@PageSize) + " [ "
+ @fldName + "] from [ " + @tblName + "] where " + @strWhere + " "
+ @strOrder + ") as tblTmp) and " + @strWhere + " " + @strOrder
end
end
exec (@strSQL)

[解决办法]
mssql 2005的通用存储过程:

@condition varchar(2000)=NULL,-- 查询条件
@top int = -1,--
@orderby varchar(200)=NULL-- 排序 desc
