SQL*LOADER example not working for REF

Question

I was working on the Oracle bulk load scripts using SQL*LOADER utility .
I have encountered an error while using the REF column option to resolve the parent-child referential integrity .
The example given in the URL http://www.csee.umbc.edu/help/oracle8/server.815/a67792/ch05.htm Example 5-9 Loading Primary Key REF Columns
does not work . and generates errors : 'SQL*Loader-418: Bad datafile datatype for column DEPT_MGR'
example :
Control File
LOAD DATA
INFILE `sample.dat'
INTO TABLE departments_alt
FIELDS TERMINATED BY `,' OPTIONALLY ENCLOSED BY `"'
(dept_no CHAR(5),
dept_name CHAR(30),
dept_mgr REF(CONSTANT `EMPLOYEES', emp_id),
emp_id FILLER CHAR(32))
Data file (sample.dat)
22345, QuestWorld, 007,
23423, Geography, 000,
Could you please suggest any solutions for this ?

Answer 1

Some of the quotes are wrong
Try the sample from the 10.2 documentation
LOAD DATA
INFILE 'sample.dat'
INTO TABLE departments_alt
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
(dept_no       CHAR(5),
dept_name      CHAR(30),
dept_mgr       REF(CONSTANT 'EMPLOYEES', emp_id),
emp_id         FILLER CHAR(32))
