关于分页加模糊查询的存储过程

select [Uid],[Usname],[Uname],[Urole],[Upicture] from Us

create proc Upage
(
@pageindex int,  ---当前页
@pagesize int,   ---显示几条
@pagecount int out,    ---总条数
@name varchar(50)   ---查询名称参数
)
as
---判断有没有查询的参数
if(@name is null)
begin
 ---查询总记录数
 select @pagecount=COUNT(*) from Us;
 select * from(select ROW_NUMBER() over(order by Usname)as num, [Uid],[Usname],[Uname],[Urole],[Upicture] from Us ) temptable where num between ((@pageindex-1)*@pagesize+1) and (@pageindex*@pagesize)
end
else
begin
 ---查询总记录数
 select @pagecount=COUNT(*) from Us where Usname like ‘%‘+@name+‘%‘;
 select * from(select ROW_NUMBER() over(order by Usname)as num, [Uid],[Usname],[Uname],[Urole],[Upicture] from Us  where Usname like ‘%‘+@name+‘%‘) temptable where num between ((@pageindex-1)*@pagesize+1) and (@pageindex*@pagesize)
 ---where num between((页码-1)*几条+1) and (页码*几条)
end
