External table in a procedure

Question

Hi,
I have an external table script to load data and I need to schedule the loading (every 10 minutes). (env: Windows XP)
I am planning on putting the external table script in a procedure and call the procedure in the DBMS utility.
But.... when I put the external table script in the procedure, I am getting compilation errors because of the DROP and CREATE (DDL) statements in the procedure.
Please help me putting the external table script in the procedure.
Thanks in advance

JT,
If the file is allways the same name, why drop and recreate externale table.
You can reuse the table even if the file was drop and recreate.
  1   CREATE TABLE EXT_RN_DEPLOY_DATA
  2   (
  3   MONITOR_ID VARCHAR2(30),
  4   SAMPLE_ID VARCHAR2(30),
  5   LATITUDE VARCHAR2(10),
  6   DEW_POINT NUMBER(18,8)
  7   )
  8   ORGANIZATION EXTERNAL
  9   ( TYPE ORACLE_LOADER
10   DEFAULT DIRECTORY DATA_FILE_DIR2
11   ACCESS PARAMETERS
12   ( RECORDS DELIMITED BY NEWLINE SKIP 1
13   BADFILE DATA_FILE_DIR2:'REVEXT%A_%P.BAD'
14   LOGFILE DATA_FILE_DIR2:'REVEXT%A_%P.LOG'
15   FIELDS TERMINATED BY ","
16   OPTIONALLY ENCLOSED BY '"'
17   MISSING FIELD VALUES ARE NULL
18   )
19   LOCATION (DATA_FILE_DIR2:'load.csv')
