Search for table names with date in the name

Hi,

I have some tables with names like:

table20130301
table20130302
table20130303
and so on, one table for each day.

I need to extract this date from the table name.
then this date is to be compared to know if it is older than 90 days ..and then some archive process is to be carried out.

I tried this for one day and I think it works...

DECLARE @a varchar(100),@count int,@temp int,
@archive_days int,@table_days int,@tbl_name varchar(100),@dt_tbl_name datetime,@dt_days int

set @archive_days = 90

select top  @tbl_name =  name 
FROM test1.sys.tables where 
type = 'u' and 
name like 'table%'
print @tbl_name

set @dt_tbl_name =  RIGHT ('' + @tbl_name + '',8)
--print @dt_tbl_name

set @dt_days = datediff (dd,@dt_tbl_name,getdate())
print @dt_days

but the problem is, the above code will run through all the tables which start with 'table%'..is this the only way to loop though the tables or is there a simpler way?

any help is highly appreciated!!!

thanks...
