使用存储过程实现分页

CREATE PROCEDURE GetRecordFromPage
@tblName varchar(255), -- 表名
@fldName varchar(255), -- 字段名以主键值
@PageSize int = 10, -- 页尺寸
@PageIndex int = 1, -- 页码
@OrderType bit = 0, -- 设置排序类型, 非 0 值则降序
@strWhere varchar(2000) = '' -- 查询条件 (注意: 不要加 where)
AS

declare @strSQL varchar(6000) -- 主语句
declare @strTmp varchar(5000) -- 临时变量
declare @strOrder varchar(500) -- 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 ["
+ @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) + " * from ["
+ @tblName + "] where [" + @fldName + "]" + @strTmp + "(["
+ @fldName + "]) from (select top " + str((@PageIndex-1)*@PageSize) + " ["
+ @fldName + "] from [" + @tblName + "] where " + @strWhere + " "
+ @strOrder + ") as tblTmp) and " + @strWhere + " " + @strOrder

if @PageIndex = 1
begin
set @strTmp = ""
if @strWhere != ''
set @strTmp = " where (" + @strWhere + ")"

set @strSQL = "select top " + str(@PageSize) + " * from ["
+ @tblName + "]" + @strTmp + " " + @strOrder
end

--print @strSQL
exec (@strSQL)
