7777,,32.6

Expected Records in table

Transaction Code : 6666
Amount :28.5

Transaction Code : 7777
Amount :32.6

You can use WHEN clause to insert one field or the other depending if col2 is null or not.
See ulcase5.ctl in your ORACLE_HOME/rdbms/demo directory.

Hi Michel,

Thanks for your prompt reply

How does this work for comma separated data file?

Regards,
John

Hi,

I was attempting the following way,

LOAD DATA
INFILE *
INTO TABLE tab1
WHEN col2 = ''
FIELDS TERMINATED BY "," OPTIONALLY ENCLOSED BY '"'
( col1,
col2
)
INTO TABLE tab1
WHEN col2 != ''
FIELDS TERMINATED BY "," OPTIONALLY ENCLOSED BY '"'
( col1,
col2 FILLER INTEGER,
col2
)
BEGINDATA
21,211111,
22, ,211111
31,311111,
32, ,311111

but it errors out saying.
SQL*Loader-350: Syntax error at line 13.
Expecting "," or ")", found "FILLER".
col2 FILLER INTEGER,
^

Thanks,
John

when col2 is null
when col2 is not null
if you use empty string.
or there is a space missing in your string constant ''.
In addition, I think your test is the opposite one and don't use the same column name in the second case. Also why not FILLER CHAR?

Use code tags to post your control file (see /forum/fa/4938/0/

button) otherwise space are unreable.
