Loading data from csv file into table - problem

 Hello, 

I have Windows 7 64 bit, Oracle 11.2.0 and I use SQL Developer 3.0.0.4. I have a CSV file with data like this:

0000000000|000000000000000000000|000000000000000000000000000

00000000|0000000000000000000000000|00000000000000000000000000

00000000|000000000000000000000000|000000000000000000000000

As you see - numbers are seperated by "|"

I want to create a table in which I will enter this data, so:

create table acc_tmp

(row_id VARCHAR2(20),

 X_NUMBER NUMBER(30),

 X_VIRTUAL_NUMBER VARCHAR2(100)

)

ORGANIZATION EXTERNAL

( 

  TYPE oracle_loader

  default directory data_dir

  access parameters

  ( 

  records delimited by newline

  fields terminated by '|'

  )

  location ('XXXXXXXXX_Numbers_PROD_2013_07_29.csv')

)

When I run it I ahve an information that: 

"table ACC_TMP created"

But, when I want to query:
