I'm sorry to bring this up again - it has been covered before on the list,
but surprisingly nobody has come up with a solution.
If anyone has come up against this problem and has been able to solve it, or
even if you were unable to solve it, I'd love to hear from you!
Oh, and the solution: 'don't use cursors' isn't a viable one as I want to
traverse a table with tens of millions of records in it and I want to avoid
fetching the whole table in one go.
thanks!

THE CODE:
#!/usr/bin/perl -w
use DBI;
use DBD::Oracle qw(:ora_types);
print "connecting to database... ";
$dbh = DBI->connect('DBI:Oracle:blah', 'blah', 'blah') || die
$dbh->errstr;
$dbh->{RaiseError} = 1;
print "done!\n";
print "preparing the cursor... ";
$sth = $dbh->prepare(q{
BEGIN OPEN :cursor FOR
SELECT c_client_name
FROM client;
END;
});
my $sth_curs;
$sth->bind_param_inout(":cursor", \$sth_curs, 0, { ora_type => ORA_RSET }
);
$sth->execute;
print "done!\n";
print "fetching... ";
while (@row = $sth_curs->fetchrow_array) {
if($row[0]){
print "result: $row[0]\n";
}
}
print "done\n";
THE PROBLEM:
When I execute it on my Redhat machine, this is what happens:
[djohnson@uklinux002 dev]$ ./test2.pl
connecting to database... done!
Segmentation fault
[djohnson@uklinux002 dev]$
However, when I execute the identical script on my DEC_ALPHA machine, it
runs fine. What is particularly surprising is the fact that the versions of
software on the DEC_ALPHA machine are older than those on the Redhat
machine.
