Because you need to pass the table name as parameter and views don't take parameter, you need to use a table valued function like:

Select * From fnReadDataFromTable('TAB_09082013');

Or, just use something like in below without a function call:

DECLARE @tablename AS NVARCHAR(261) = N'TAB_09082013';
EXECUTE(N'SELECT * FROM ' + @tablename);

You would have to use dynamic sql to generate each of the 500 queries and they use sp_executesql to execute them individually.

You can use this code, hope this is what you need.

declare @min int, @max int, @tbl nvarchar(128), @sql nvarchar(max)

select name, ROW_NUMBER() over(order by name) as rno into #t
 from sys.tables where name like 'TAB_%'

set @min=1 
set @max =(select MAX(rno) from #t)

while @min <= @max
set @tbl=(select name from #t where rno=@min)
set @sql='select * from ' + @tbl
exec (@sql)
set @min=@min+1
drop table #t

Is all table's has same columns?

if yes you can create a temp\physical table with the same column name and change the @sql variable string value to....

set @sql='insert   into <#TAB_Result> select  * from ' + @tbl
