External table wont display

Question

db=xe
Hello,
I am attempting to create an external table to reference a csv file that contains exif data from images. The exif data presents the date in the following form 2011:12:03 16:47:27
I have constructed the external table like this;
CREATE TABLE metadata_external
( sourcefile VARCHAR2 (255 CHAR)
, createdate VARCHAR2 (255 CHAR)
ORGANIZATION EXTERNAL
( TYPE ORACLE_LOADER
  DEFAULT DIRECTORY "UPLOAD_DIR"
  ACCESS PARAMETERS
    ( RECORDS DELIMITED BY NEWLINE
      NOBADFILE
      NOLOGFILE
      FIELDS TERMINATED BY ','
      MISSING FIELD VALUES ARE NULL
      ( sourcefile
      , createdate
  LOCATION
    ( "UPLOAD_DIR":'metadata_external.csv'
) REJECT LIMIT UNLIMITED;You will note that I have given the createdate column a datatype of varchar2. This was to avoid any problems with formating so that I could use the to_date function when inserting into other tables.
But the following code will not display anything but throws the following error;
ORA-29913: error in executing ODCIEXTTABLEOPEN callout
ORA-29400: data cartridge error
KUP-00554: error encountered while parsing access parameters
KUP-01005: syntax error: found "minussign": expecting one of: "binary_double, binary_float, comma, char, date, defaultif, decimal, double, float, integer, (, nullif, oracle_date, oracle_number, position, raw, recnum, ), unsigned, varrawc, varchar, varraw, varcharc, zoned"
KUP-01007: at line 8 column 1
ORA-06512: at "SYS.ORACLE_LOADER", line 19I suspect that the : separators in the date are causing the problems.
Would anyone have some suggestions to fix this problem?
Thank You
Ben
