Another way of doing this is getting the resultset count before firing the required query i.e.
firing a select count(*) ROWCOUNT from table where id = 1 If ROWCOUNT is 0 , then u dont need to fire the second SQL (which is  select * from table where id = 1) u need to fire the second SQL only if the first SQL returns a value greater than 0 )
For example, 
my $sql = <<EOF;
    select count(*) ROWCOUNT from EMPLOYEE where employee_id = 1
EOF
    ;
my $sth = $dbh->prepare($sql);
$sth->execute;
my $employee_count_row = $sth->fetchrow_hashref;
$sth->finish;

print "NO RECORDS FOUND" unless $auth_row->{'ROWCOUNT'} > 0;
 ...fire the second SQL if ROWCOUNT > 0
