External tables with undelimited fields

At the Oracle site there is an example of external tables.
Part of that SQL+ session states

FIELDS TERMINATED BY "|" LDRTRIM  .
The file i am trying to use is downloaded from a mainframe and there is nothing terminating each field.
If i just leave that line out it assumes each field is larger that 255 and sees nothing.
What should i use here?

   From a SQL*Plus session logged on to the SH schema, run @create_external_table.sql.
   The results are as follows:

   @create_external_table

   set echo on

I think the format should be the same as in a SQL*Loader control file. You can specify the field positions instead of a delimiter. Here'a an example from the Oracle manual about the SQL*Loader control file format (only the field descriptions):
deptno POSITION(1:2)  INTEGER EXTERNAL(2)
              NULLIF deptno=BLANKS,
       job    POSITION(7:14)  CHAR  TERMINATED BY WHITESPACE
              NULLIF job=BLANKS  "UPPER(:job)",
       mgr    POSITION(28:31) INTEGER EXTERNAL
              TERMINATED BY WHITESPACE, NULLIF mgr=BLANKS,
       ename  POSITION(34:41) CHAR
              TERMINATED BY WHITESPACE  "UPPER(:ename)",
       empno  POSITION(45) INTEGER EXTERNAL
              TERMINATED BY WHITESPACE,
       sal    POSITION(51) CHAR  TERMINATED BY WHITESPACE
              "TO_NUMBER(:sal,'$99,999.99')",
       comm   INTEGER EXTERNAL  ENCLOSED BY '(' AND '%'
              ":comm * 100"

So iin your case the command should be something like that:
CREATE TABLE sales_delta_xt
    (
     prod_id NUMBER(6),
     cust_id NUMBER,
     time_id DATE,
     channel_id CHAR(1),
     promo_id NUMBER(6),
     quantity_sold NUMBER(3),
     amount_sold NUMBER(10,2)
    )
    ORGANIZATION external
    (
     TYPE oracle_loader
     DEFAULT DIRECTORY data_dir
     ACCESS PARAMETERS
      (
       RECORDS DELIMITED BY NEWLINE CHARACTERSET US7ASCII
       BADFILE log_dir:'sh_sales_%p.bad'
       LOGFILE log_dir:'sh_sales_%p.log_xt'
       (
        prod_id POSITION(1:6) INTEGER,
-- you'll have to calculate the positions of the rest of the fields
-- because you haven't specified the length of the second column
-- and I have no idea what it is :)
        cust_id POSITION(?:?) INTEGER,
        time_id POSITION(?:?) DATE,
        channel_id POSITION(?:?) CHAR,
        promo_id POSITION(?:?) INTEGER,
        quantity_sold POSITION(?:?) INTEGER,
        amount_sold POSITION(?:?) FLOAT
       )
      )
     location
      (
       'salesDelta.dat'
      )
     )REJECT LIMIT UNLIMITED NOPARALLEL;

Hope that helps!

Got a good feeling about this.  Will try it tomorrow afternoon.  Thanks.

just check out that fields in file are always of the same (fixed) length. i.e. if field PROMO_ID=3 then number 3 should be left or right padded with 5 spaces.

in case your records in file aren't fixed length, they may be separated with spaces. then you can change TERMINATED BY "|" to TERMINATED BY " " (empty space between "")
