Presumably you meant "why isn't that data structured relationally"
instead of "why extract data from a database" :) One possible answer
is that it's someone else's database.

Exactly ! I must use these data "as is".

That'll throw a "bad generator" error. Did you mean this:

  {ok,Tokens,_} = erl_scan:string("(1,2),(3,4)"),
  [X || {integer,_,X}  <- Tokens].

?
