OWB 10gR1 Convert Date format (mm-dd-yyyy) to (yyyy-mm-dd)

Question

Hi All,
In OWB 10gR1, I have flatfiles with Date fields having the format (mm-dd-yyyy). I want to load this data into the Staging table in (yyyy-mm-dd) format. How could I do this conversion in my staging mapping ?
Using external tables is not an option.
An detailed answer will be extremely helpful.
Thanks community.

Wich is this field's datatype in database? Is it date or char? If you are going to store it as a date datatype, you don't have to worry about the date format.
Have you tried using the Expression Operator to perform the date string conversion in your mapping? Sorry about this lame drawing, but I think it will help you understand:
source_table ------------ALL_COLUMNS_EXCEPT_DATE_DATATYPE-------TARGET_TABLE
             |                                                 |
             +-------EXPR{TO_DATE(DATE_FIELD, 'DATE_FORMAT')}--+In this example, you'll use an expression operator to convert the date string in the format you want. Map other attributes directly to your target table (or other transformations you need to perform).
This is the generated script of a dummy plan I've built here:
OPTIONS ( ERRORS=50, BINDSIZE=50000, ROWS=200, READSIZE=65536)
LOAD DATA
  CHARACTERSET WE8MSWIN1252
  INFILE '{{LOC_FILE.RootPath}}load.csv'
INTO TABLE "LOAD_TARGET"
  APPEND
  REENABLE DISABLED_CONSTRAINTS
  FIELDS
    TERMINATED BY ';'
    OPTIONALLY ENCLOSED BY '"'
  "COD" POSITION (1) INTEGER EXTERNAL ,
"NOME" CHAR ,
"DATA" CHAR "to_date( :\"DATA\" , 'yyyy-mm-dd')"
