Hi Srini,
You can use the normal file upload functionality to do this.
1 - Create a page region and add in a File Browse item - I'll call it P1_FILE_NAME
2 - Create a button in that region, I'll call it P1_UPLOAD_BUTTON, and set it to branch back to the same page
3 - Create a TextArea item - I'll call it P1_FILE_CONTENTS
4 - Create a page process, called P1_UPLOAD_FILE, and triggered by the P1_UPLOAD_BUTTON
5 - Use the follownig code for the process:
declare
v_clob clob;
v_blob blob;
v_varchar2 varchar2(30000);
BEGIN
SELECT blob_content into v_blob FROM APEX_APPLICATION_FILES where name = :P1_FILE_NAME;
v_clob := wwv_flow_utilities.blob_to_clob(v_blob,'utf-8');
:P1_FILE_CONTENTS := wwv_flow_utilities.clob_to_varchar2(v_clob);
:P1_FILE_NAME := '';
delete from APEX_APPLICATION_FILES WHERE NAME = :P1_FILE_NAME;
END;When you select the file and click the Upload button, the file is uploaded into the APEX_APPLICATION_FILES table. The contents of the file is put into a BLOB field. The above code, converts that BLOB into a CLOB and then into a VARCHAR2 value - you can then change P1_FILE_CONTENTS to that value. Finally, the code removes the file from the table and resets the File Browse field.
Note that this assumes that the file contains nothing but text and is no more than 30,000 characters in length.
