SQLLDR: Loading Ref Columns [message #202447]

Hello -

Is anybody familiar with the object-oriented feautures of oracle?
I have a couple of tables that I need to load using sqlldr, one one of them contains a column that is a REF to objects in the other table.

The types are declared as:

CREATE OR REPLACE TYPE DirectorType AS OBJECT (
did NUMBER(5),
name VARCHAR2(20),
birthdate DATE,
movies NUMBER
);

CREATE OR REPLACE TYPE MovieType AS OBJECT (
mid NUMBER(5),
title VARCHAR2(20),
year DATE,
director REF DirectorType
);

And the tables as follows:

CREATE TABLE DirectorTab OF DirectorType (did PRIMARY KEY);
CREATE TABLE MovieTab OF MovieType (mid PRIMARY KEY);

Here is the control file for loading the directorTab:

load data
infile './director.tbl'
into table directorTab
fields terminated by "," optionally enclosed by '"'
( did INTEGER EXTERNAL(5),
name CHAR(20),
birthdate "TO_DATE(:birthdate,'MM/DD/YYYY')",
movies INTEGER EXTERNAL(3) )

sample data:
10001,Leoni,09/11/1971,2,
10002,Smith,02/23/1956,9,
10003,Estwood,11/02/1909,28,

This works just fine! The problem is loading the movie table. Here is the control file:

LOAD DATA
INFILE './movie.tbl'
INTO TABLE movieTab
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
( mid INTEGER EXTERNAL(5),
title CHAR(20),
year "TO_DATE(:year,'YYYY')",
director REF (CONSTANT 'DIRECTORTAB', did),
did FILLER CHAR(5) )

sample data:
4, "Earth", 1997, 10003,
5, "Blast", 2006, 10001,

This is exactly the same as described in oracle documentation for loading primary key REF columns (http://download-east.oracle.com/docs/cd/B19306_01/server.102/b14215/ldr_loading.htm#i1006786)
but I get the following error:
Record 1: Rejected - Error on table MOVIETAB, column DID.
error converting data
ORA-26007: invalid value for SETID or OID column

It seems like sqlldr thinks that the did column should be a system generated OID and expects 32 bytes of hex chars.

If anybody has encoutered this before or has an alternative, I would greatly appreciate it! Thanks,

-> Tariq
