Variable filename external table

Question

I have written a script to import data from a .csv into a table in Apex:
CREATE TABLE APEX_USER_002.INK_KASSA_LOAD
KASS_DTM      VARCHAR2(255),
       KASS_ID       VARCHAR2(255),
       KASS_VKP_COD  VARCHAR2(255),
       KASS_VKP_OMS  VARCHAR2(255),
       KASS_COD VARCHAR2(255),
       KASS_OMS   VARCHAR2(255),
       KASS_PRS_COD VARCHAR2(255),
       KASS_PRS_OMS VARCHAR2(255)
ORGANIZATION EXTERNAL
  TYPE ORACLE_LOADER
  DEFAULT DIRECTORY AFM_KASSA_IN
  ACCESS PARAMETERS
    RECORDS DELIMITED BY NEWLINE CHARACTERSET WE8MSWIN1252
      LOGFILE AFM_KASSA_LOG: 'log.log'
    BADFILE AFM_KASSA_BAD: 'badfile.bad'
    NODISCARDFILE
    SKIP 1
    FIELDS TERMINATED BY ';'
    OPTIONALLY ENCLOSED BY '"'
    LRTRIM
    MISSING FIELD VALUES ARE NULL
KASS_DTM,
       KASS_ID,
       KASS_VKP_COD,
       KASS_VKP_OMS,
       KASS_COD,
       KASS_OMS,
       KASS_PRS_COD,
       KASS_PRS_OMS
    LOCATION  ('variable_filename.csv')
It works fine when I put the name of the .csv hardcoded in the script. Like this: LOCATION ('Kassa_20130406130014.csv')
I have written a function which returns the filename, but when I use the function in LOCATION (function()) I get an error: ora-00905: missing keyword
How can I call a function in LOCATION ()?

Hi,
I'm not sure but I think you need re-create external table.
Create procedure that drops and re-creates external table dynamically with new file name.
Or use e.g. DBMS_SCHEDULER to call OS script that renames file always to same name for external table.
