Try this:

SELECT * FROM $table_name ....

SELECT * is not a good idea to just blindly write, though.  In general 
it's a much better idea to explicitly name the columns you know you need 
  (it's more efficient, you don't get any nasty surprises when someone 
adds another column to the table, you will get an explicit error when 
someone drops a column your application actually needs...)
