Обсуждение: PLPERL

Hi

I want to implement  a stored procedure written in plperl
which is able to evaluate expressions.
i would like to do something like :

...
 my ($a,$b,$c);
 $a=1;
 $b=2;

 eval ''$c=$a+$b;'';
 return $c;
...
Is it possible to do expression evaluation in plperl or other language?

Huh... why don't you try standard Perl expression evaluation?

... my ($a, $b);
    $a = 1;
    $b = 2;
    return $a + $b;
...

But maybe the answer is too simple, so this isn't really the question?
