How to read a line from a file which contains 45000 characters?

Question

Hi all,
     Iam a receiving a .CSV file which contains n number of rows ,each row has a data seperated with delimiter.
These values based on delimiter it is seperated and certain validations are handled.
Iam using UTL_FILE.GET_LINE operator to read the value and store it in a variable which is declared as l_text VARCHAR2(30000).
when we receive a line which contains huge characters say 45000 then it throws an error(Unable to read the file).
Only on rare cases we used to receive these kind of files with huge size.
Kindly help to solve this issues.

Hi Siva,
Are you trying to use data from this .csv file into your realtion tables. If yes and If you are using 11g Oracle database. I would suggest you create External Tables using the below query,
http://www.oracle.com/technetwork/issue-archive/2011/11-mar/o21nanda-312277.html
STEP1: You need a Directory where your SCHEMA has read/write access. Store the csv file in that directory.
STEP2: Create an EXTERNAL Table script. Please refer the above URL. Examples are for coma delimiter (,); replace it with your pipe (|) in the code
STEP: Once your external table is created you can simply create a relational table as below:
CREATE  TABLE relation_table
  AS
SELECT * FROM external_table;
