I have a problem in a perl script that I'm writing. When I run the script it hangs after prepare(). I've tried to run the update statement from SQL Developer and it works fine. I've also tried to print out all parameters and they are correct. What am I missing here? my $upd = 'update ngs.pp_subscr_data set address=?, city=?, postalcode=?, kennitala=?, email=?, firstname=?, lastname=?, last_upd=systimestamp where snb=?'; my $s = $dbh->prepare ($upd) || exitError(-9802, 'Couldn\'t prepare update statement.'); $s->execute($addr, $city, $pcode, $ktala, $email, $fname, $lname, $snb) Thanks.
