Could someone post some sample code showing how to insert text greater than 4000

Could someone post some sample code showing how to insert text greater than 4000 characters in length into an Oracle 10g CLOB field?
I am using the Oracle OLEDB provider and ATL in C++.
My naive attempt returns the error ‘ORA-01704: string literal too long’ whenever the text I am attempting to insert goes over 4000 characters in length.
I’m guessing I need to parameterise the 4000+ character string somehow but I’m not sure how to do that…

    I eventually got this working.
    In case anyone else has the same problem, I inserted the value EMPTY_CLOB() then used the ISequentialStream interface to stream the text into the empty field.
    The Microsoft mydyntext sample shows how to do this.
