Re: how to use exp/imp only for specific columns?

Ok

How about if you use the form in this example from the manual. The Key bit being
FIELDS TERMINATED BY "," OPTIONALLY ENCLOSED BY '"' Surely the chances of the data containing the combination "," other than between field, columns would be very low.

Regards Kevin

CREATE TABLE emp_external (
employee_id NUMBER(6),

last_name VARCHAR2(20),

email VARCHAR2(25),

hire_date DATE,

job_id VARCHAR2(10),

salary NUMBER(8,2)

)

ORGANIZATION EXTERNAL (TYPE oracle_loader

DEFAULT DIRECTORY admin

ACCESS PARAMETERS (

RECORDS DELIMITED BY newline

BADFILE 'ulcase1.bad'

DISCARDFILE 'ulcase1.dis'

LOGFILE 'ulcase1.log'

SKIP 20 FIELDS TERMINATED BY "," OPTIONALLY ENCLOSED BY '"' (

deptno INTEGER EXTERNAL,

dname CHAR,

loc CHAR

)

)

LOCATION ('ulcase1.dat')

)
