Hello,

I am trying to convert a database function that is written in perl to a 
PL/pgSQL function.  However, there a a couple of lines that I don't
think can be converted.

First line:
my @active_tables=split(/,/,$tables);

Is there anyway to split a variable like the perl split above?

Second line:

 if ($r=~/^-([0-9]?)([A-z_]+)/)
 {
    my $locid = $1;
    my $table = $2;

Is there any way to to regular expressions similar to above.  I need to
be able to save the matches for later use.  I know you can do regular
expressions in sql but I can't find any equivalent for the above.

Now you may be saying that why don't I just leave it in perl?  Well, I
would like to but my boss wants me to convert this to PL/pgSQL....long
story.  Anyway, if it can't be done it can't be done.  But I was just
wondering if anyone has any advice.

Thanks for the help.

Later
