Sorry to be a Johnny come lately on this (pun intended)
I have been playing with this myself and like you chaps have come up with a
blank. End up with ORA-00942 error
I did spend some time to see how the python guys did it but as I can see
they just did it as a cursor which I think we can do as well in DBD::Oracle.
It is too late at night for me to give it a try though.
I have stepped though all the code and can see nothing awry.
I think our only alternative is to build up the clob in hunks then try to
run it using the LOB Locator Methods We could indicate this with a new ORA
type called ORA_XMLTYPE or alike????
Cheers
Of by the way any of you going the

I ran this against v1.19 and had the same limit.

Thanks Philip for the extra info.
I've attached a test case I'm working with .. wondering if anyone
using DBD 1.19 can try this out too and report the results?
Ron, can you check this also ... maybe your code is different in some
way?
For me the limit is at 63/64 elements (results are in the file)
perl xmltypeinsert-testcase.pl ORCL scott tiger 63
- is ok
perl xmltypeinsert-testcase.pl ORCL scott tiger 64
- fails

I can confirm I have the same problems as Paul when inserting large
XMLType.
Running on:
1. SUSE LINUX Enterprise Server 9 (i586)
2. DBI v1.50
3. DBD::Oracle v1.18
4. Oracle client: 9.2.0.4.0

I tried your code (are you explicitly typing the bind to
veryI'm assuming not), and for small data sizes its ok, but once I go
ilarge it fails.
# fyi, I'm creating a long structure like this. max i 10 is ok, max
on3000 is not:
my @books;
my %dslong;
for (my $i=1; $i<3000; $i++) {
push(@books, {id => $i, title => [ "the book $i title" ] } );
}
$dslong{"book"} = \@books;
# and binding like this:
$sth->bind_param(":file_header", XMLout( \%dslong , RootName =>
"books") );
NB: I'm presently testing this with DBD-Oracle-1.17 and DBI-1.52-r1

My files are around the order of 37Kb in size and I do nothing
special
with them (aside from convert the text into XML). My user has only
insert on the table with the XMLTYPE in it.
Does the user running the Perl program have INSERT privs on the
table?
Is there a synonym issue or a role issue?

Subject: DBD::Oracle - Any advance on inserting CLOB to XMLTYPE?
It seems the current state of affairs is that for inserting to
XMLTYPE
fields:
a) for <32k, can just insert text
b) for >32k, must insert to CLOB, then use a procedure to update
XMLTYPE (see
for a summary of the details)
Personally I've tried just about every trick in the book to try and
get a direct-insert of large xml documents into xmltype fields, but
to
no avail.
What troubles me is that this _should_ work:
# NB: CREATE TABLE tryit ( formname VARCHAR(25), x XMLTYPE )
INSERT INTO tryit (formname, x) VALUES (?, XMLTYPE(?))"
$sth = $dbh->prepare( "INSERT INTO tryit (formname, x) VALUES (?,
XMLTYPE(?))" );
$sth->bind_param(1, "INSERTXMLTYPE" );
$sth->bind_param(2, XMLout( \%dslong , RootName => "books"), { TYPE
=>
SQL_CLOB } );
$sth->execute or warn "INSERTXMLTYPE creation failure";
but it actually just gives ORA-00942: table or view does not exist.
this is a bogus message (search metalink for "XMLTYPE ORA-00942").
try
an alternative like "INSERT INTO tryit (formname, x) VALUES (?,
XMLTYPE(CAST(? as CLOB)))" and you get ORA-00932: inconsistent
datatypes.
All of the above is old news I think.
Why I raise this now is that I discovered the python guys seem to
have
got it working OK. See
http://blog.gmane.org/gmane.comp.python.db.cx-oracle/month=20050401
connection = cx_Oracle.Connection("user/pw <at> tns")
cursor = connection.cursor()
cursor.setinputsizes(value = cx_Oracle.CLOB)
cursor.execute("insert into xmltable values (xmltype(:value))",
value = "A very long XML string")
Seems very much like a binding issue on the DBI/DBD side.
Any thoughts?
