How Do I Select Tablename In Subquery

hi all how are you today i am not good because i can't set this variable in this query please read this thanks

create table aaa1 (id_no int, name varchar(20))
go
create table aaa2 (id_no int, name varchar(20))
go

insert into aaa1 values (1,'rahmi')
insert into aaa1 values (2,'atilganer')
insert into aaa1 values (3,'hasan')

insert into aaa2 values (4,'rahmi')
insert into aaa2 values (5,'atilganer')
insert into aaa2 values (6,'hasan')

/* declaring any numeric variable*/
declare @id_no_var int
/* and set variable to max table name's (aaa2 table in this example)
id_ no column

note :insqlhelp and insqlhelp2 is an alias for tablename query (recommended from sql help
*/

set @id_no_var =
(select max(id_no) from
(select max(name) insqlhelp from
sysobjects where name like 'aa%') insqlhelp2 )


this query return:

Server: Msg 207, Level 16, State 3, Line 3
Invalid column name 'id_no'.

this error returned because max(id_no) column is absent

if you are run
select * from
(select max(name) insqlhelp from
sysobjects where name like 'aa%') insqlhelp2

this query return that

insqlhelp ---------------
aaa2

(1 row(s) affected)

this mean that my table name query returned table name but i cant use this name in any other query (i think because of daclaring alias "insqlhelp, insqlhelp2")

other way is

set to any other text variable to table name,
and concetanate to query,
and execute with exec

but in this way you cant set to my int variable

please help me thanks for all
