CSV-Upload in ORACLE database

Question

Hello,
I'm currently working on a workflow-project in Oracle APEX with an ORACLE database (10g) where - as a special feature - I have to implement a page where the User can upload a CSV - file into the database tables by himself.
The problem I have is that I don't find a way to fullfill the upload. Is there any special command in ORACLE or predefined scrip to upload a csv - file in an existing table like for example the MYSQL - command LOAD DATA INFILE?

Hi,
Just a quick question? are you trying to load data from the cvs or are you loading the file itself into a table. If you're to load data from the cvs then easier Sqlloader else if loading the file itself and Apex then the link will be helpful. or you use this example of web:
     CREATE TABLE my_docs
          (doc_id NUMBER,
          bfile_loc BFILE,
          doc_title VARCHAR2(255),
          doc_blob BLOB DEFAULT EMPTY_BLOB() );
     AS
PROCEDURE doc_dir_setup;
PROCEDURE list (in_doc IN VARCHAR2);
PROCEDURE load (in_doc IN VARCHAR2,
in_id IN NUMBER);
PROCEDURE search (in_search IN VARCHAR2,
in_id IN NUMBER);
END mydocs;
CREATE OR REPLACE PACKAGE BODY
mydocs
     AS
vexists BOOLEAN;
vfile_length NUMBER;
vblocksize NUMBER;
PROCEDURE doc_dir_setup IS
BEGIN
EXECUTE IMMEDIATE
'CREATE DIRECTORY DOC_DIR AS'||
'''"E:\jkoopmann\publish\databasejournal\Oracle"''';
END doc_dir_setup;
PROCEDURE list (in_doc IN VARCHAR2) IS
BEGIN
UTL_FILE.FGETATTR('DOC_DIR',
in_doc,
               vexists,
               vfile_length,
               vblocksize);
IF vexists THEN
dbms_output.put_line(in_doc||' '||vfile_length);
END IF;
END list;
PROCEDURE load (in_doc IN VARCHAR2,
in_id IN NUMBER) IS
temp_blob BLOB := empty_blob();
bfile_loc BFILE;
Bytes_to_load INTEGER := 4294967295;
BEGIN
bfile_loc := BFILENAME('DOC_DIR', in_doc);
INSERT INTO my_docs (doc_id, bfile_loc, doc_title)
VALUES (in_id, bfile_loc, in_doc);
SELECT doc_blob INTO temp_blob
FROM my_docs WHERE doc_id = in_id
FOR UPDATE;
DBMS_LOB.OPEN(bfile_loc, DBMS_LOB.LOB_READONLY);
DBMS_LOB.OPEN(temp_blob, DBMS_LOB.LOB_READWRITE);
DBMS_LOB.LOADFROMFILE(temp_blob, bfile_loc, Bytes_to_load);
DBMS_LOB.CLOSE(temp_blob);
DBMS_LOB.CLOSE(bfile_loc);
COMMIT;
END load;
-- in_id can be a db sequence---
PROCEDURE search (in_search VARCHAR2,
in_id NUMBER) IS
lob_doc BLOB;
Pattern VARCHAR2(30);
Position INTEGER := 0;
Offset INTEGER := 1;
Occurrence INTEGER := 1;
BEGIN
Pattern := utl_raw.cast_to_raw(in_search);
SELECT doc_blob INTO lob_doc
FROM my_docs WHERE doc_id = in_id;
DBMS_LOB.OPEN (lob_doc, DBMS_LOB.LOB_READONLY);
Position := DBMS_LOB.INSTR(lob_doc, Pattern, Offset, Occurrence);
IF Position = 0 THEN
DBMS_OUTPUT.PUT_LINE('Pattern not found');
ELSE
DBMS_OUTPUT.PUT_LINE('The pattern occurs at '|| position);
END IF;
DBMS_LOB.CLOSE (lob_doc);
END search;
BEGIN
DBMS_OUTPUT.ENABLE(1000000);
END mydocs;
How to Use
log into your database of choice as the SYS user
compile the package
     SQL> @mydocs.sql
set serveroutput on
     SQL> set serveroutput on
initial setup of directory object where your documents live
     SQL> exec mydocs.doc_dir_setup
Check to make sure you can read one of your documents on disk.
     SQL> exec mydocs.list('name.csv');
Load your document into the database
     SQL> exec mydocs.load('name.csv', 1);
Search your documents for a string pattern
     SQL> exec mydocs.search(Search Pattern', 1);
