The arguments of the functions come from outside the database, but the
function itself uses the datas in the database.

Like "Tell me how much i spent between the 4th and the 7th og this month
?" uses 4 and 7 as arguments, but need to fetch the datas in the
database.
Clear enough ? :-)

What do you mean by table function ?
