As others have already stated, Perl is very robust in the exception handling department.

There's no direct boolean type, but that really should not matter. The 'if' statement detects 0 as false and non-zero as true.

Here's a trivial example;

my $sql=q{select rownum from all_users order by rownum}; my $sth = $dbh->prepare($sql,{ora_check_sql => 0}); $sth->execute;

while( my $ary = $sth->fetchrow_arrayref ) {

   my $rownum = $ary->[0];
   my $bool = $rownum % 2; # % is modulus operator    if ($bool) {

      print "this is true - $rownum : $bool\n";    } else {

      print "this is false - $rownum : $bool\n"    }
}
