Yes.  The argument in the if statement is not numeric.  It clearly isn't, since
it has a comma in it.

I'm sure that the Mr. Harris knows much more about perl than I do.  > is
supposed to be a numeric comparitor, but I believe it is used here to check
whether a string is non-empty.  Maybe this is "normal" perl.

I wrote a short perl script to just check whether this works on something
containing a comma, and it does work.  Obviously, sometimes it does not work,
since we've both seen this error.

I couldn't locate a perl function "tell me if the argument is numeric", or
"tell me if the argument is a string", so I'm not sure how to fix this.

Instead of:

  if ($rowids > 0) {

one might write:

  if (defined($rowids) &&
      ($rowids ne "0"))

or maybe just

  if ($rowids ne "0")

I submitted a query like yours few days ago and nobody made a comment.

Maybe it's not seen in other environments.

I'm running perl 5.8.2 on RedHat Linux 7.
