My code looks like following
foreach (@abc)
{
$sth = $dbh->prepare("select distinct X from Y where P='$_'");
$sth->execute;
$reference = $sth->fetchall_arrayref();
if(@$reference eq '')
{
print "$_ in empty";
}
}
For some values of $_ the $reference has some value and is empty for others.
How do I check ?
I tried
if(@$reference eq '')
DIDN'T WORK !!!
Help is appreciated.
Thank you
Aman
