Your problem is almost certainly because one of your bound variables
$homeid
$code
$text
$pid
$street
$city
$state
$zlastupdated
is set to a reference. You can only bind values that are set to a
string, a number, or undef. You should check the values of your
variables before each insert to find where it is going wrong.
Also, if you are executing the insertion in a loop then you should first
prepare it outside the loop, otherwise the same SQL statement is
wastefully being prepared many times. Something like
my $insert = $dbh->prepare(q{insert into zillow_table values
(?,?,?,?,?,?,?,?)});
foreach (...) {
$insert->execute($homeid,$code,$text,$pid,$street,$city,$state,$zlastupdated);
}
