Well, considering id is your primary key and therefore very probably
unique, you could as well do: select ser, 1 from tab1 where id=$1;

Otherwise, whatever interface you're using is likely to have a rowcount

If that's not what you're looking for, please don't make us guess what
you want to achieve.
