Question : How to insert data with more than 4000 char in clob datatype in oracle 9 i

Hi Experts ..
I am trying to migrate postgreSQL database to oracle 9i. I have scripts from postgreSQL to create tables and to insert data in to oracle. I have data with more than 4000 chars in a column. For that i used clob data type in oracle. When i am trying to run my script for inserting data it give me an error like.
"The string literal is longer than 4000 characters.
*Action: Use a string literal of at most 4000 characters.
Longer values may only be entered using bind variables. "

Can any one help me with this please. thanks in Advance.

Answer : How to insert data with more than 4000 char in clob datatype in oracle 9 i

I had faced similar problems while migrating data from sybase db to oracle9i. There are some help documents in oracle's metalink.oracle.com site.

However I resorted to migrating the data using java program.
At first fill the clob field using "EMPTY_CLOB()". Then update using java programs as attached below(not a complete code).

                       
         
           
           
             String sql = "SELECT clobColumn, recordId FROM clobTable FOR UPDATE";
conn.setAutoComit(false); //make sure autocomit is false
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery(sql);
while( rs.next()){
       CLOB clob = (CLOB)rs.getClob(1);
       Writer clobWriter = clob.setCharacterStream(1L);
       clobWriter.write("data from text file for the recordId");
       clobWriter.close();
}
con.commit();
//make sure you comit
