对于SQLServer数据库,可以在查询分析器中执行以下代码,生成分页存储过程
cr�ate proc AbsolutePages
(
@PageSize int=0 , --每页显示的记录数
@PageCurrent int= , --当前要显示的页号
@FdName varchar(00)='' , --主键名或者标识列名
@Sel�ctStr varchar(2000)='', --sel�ct子句,不包含sel�ct关键字,如:*或者id,UserId,UserName等。
@FromStr varchar(000)='', --from子句,不包含from关键子,如:myTable或者myTable,yourTable
@Wh�reStr varchar(2000)='', --wh�re子句,不包含wh�re关键字,如空的,或者 id>2 等
@OrderByStr varchar(000)='' --order by 子句,不包含order by 子句 ,如id desc,UserId asc 等
)
as
------------------定义局部变量------------------
declare @Id varchar(20),@Id2 varchar(20) --开始和结束的记录号

declare @Sqls nvarchar(4000) --最终组合成的Sqls语句
