Another option is to export your file as Formatted text (space delimited). This will create a fixed format file. You can either create an external table to access the file or use sqlloader to load it. In your control file or access parameters you will specify the positions of the fields you are interested in. Your control file will look something like this:
OPTIONS (BINDSIZE=50000,ERRORS=50,ROWS=200,READSIZE=65536)
LOAD DATA
CHARACTERSET US7ASCII
INFILE '/home/FIXED_FORMAT.dat' "FIX 58"
CONCATENATE 1
INTO TABLE "EMP2"
APPEND
REENABLE DISABLED_CONSTRAINTS
"ID" POSITION(1:2) INTEGER(2) ,
"REGION" POSITION(3:3) INTEGER EXTERNAL(1) ,
"DEPT" POSITION(4:6) INTEGER EXTERNAL(3) ,
"HIRE_DATE" POSITION(7:14) DATE(8) "mmddyyyy" ,
"SALARY" POSITION(15:19) DECIMAL(9,2) ,
"NAME" POSITION(20:34) CHAR(15)
SQLDeveloper does not currently provide an option to import fixed format files.
