Help on External Tables

Question

Hi,
I have created the following external table, ext_tab and it got created in the database. This external table, ext_tab, is pointing to a Excel file converted to a CSV file
create table ext_tab (ID NUMBER(20))
Organization external (type oracle_loader
          default directory external_dir
access parameters (records delimited by newline
          fields terminated by ‘,’)
location (‘excel_tab.csv’));
The problem which I am getting is when I am trying to Select query the above table, it gives me the following error.
SQL> select * from ext_tab;
select * from ext_tab
ERROR at line 1:
ORA-29913: error in executing ODCIEXTTABLEOPEN callout
ORA-29400: data cartridge error
KUP-04063: unable to open log file EXT_TAB_1760_1484.log
OS error The data is invalid.
ORA-06512: at "SYS.ORACLE_LOADER", line 14
ORA-06512: at line 1
I would be grateful if you could help me in rectifying the above problem.
Thanks in advance,
MAK

Run this code (change directory name etc..) and look at the log file and bad file..
