sql - How is the Order By working in this query - 


select * tt  order (select age            ttt            name='tandel'           );

result is,

john    2 praveen 2 kumar   2 rakesh  2 wasib   2 gurung  2 dayalan 5 deepak  2 tandel  5 raghu   5 giga    5 deepa   5 devaraj 2

note: table tt , ttt both have same data.

quite simply, it's not working. order requires column or columns, if random data passed instead of column names, nothing.
