Sorry, wrong Forum - should be in MySQL->MaxDB !!!

How can I add large ASCII-Text into an Column defined as Long ASCII. I tried prepare-execute so far but I cannot add text bigger than the Parameter _PACKET_SIZE.

$sdbquery="INSERT INTO T_DATA (IDGRIB, TXT, LEN) VALUES (?, ?, ?)";
my $sth1 = $maxdb->prepare($sdbquery) or die "$DBI->err \n $DBI->errstr \n"; $sth1->bind_param (1, $idgrib);
$sth1->bind_param(2, $data);
$sth1->bind_param (3, length($data));
$sth1->execute() or die "$DBI->err \n $DBI->errstr \n";
$sth1->finish;

or

$sdbquery="INSERT INTO T_DATA (IDGRIB, TXT, LEN) VALUES (?, ?, ?)";
my $sth1 = $maxdb->prepare($sdbquery) or die "$DBI->err \n $DBI->errstr \n";
my $ldata=length($data);
$sth1->bind_param_inout(1, \$idgrib, 10);
$sth1->bind_param_inout(2, \$data, 5000000);
$sth1->bind_param_inout(3, \$ldata, 10);
$sth1->execute() or die "$DBI->err \n $DBI->errstr \n";
$sth1->finish;

After adding several rows I can see only thos files which are smaller than _PACKET_SIZE.

select MAX(LEN) FROM T_DATA -> 88667 (_PACKET_SIZE = 90000)
select MAX(LEN) FROM T_DATA -> 130010 (_PACKET_SIZE = 131072)
