Respected Sir,

Thanks for the example but my proble is as follows

I have a stored procedure in oracle which i am calling in java through callable statement ..declaration for the procedure is as follows...

create or replace procedure abc(,,,,cursor_my in out ref cursor)
is
begin
open cursor_my for
select * from some_table;
end;

later calling this proc as

CallableStatement stmt=connection.prepareCall("BEGIN abc(?,?,?,?); END;");
stmt.setInt(1,3)
...
stmt.registerOutParameter(4, OracleTypes.CURSOR); //REF CURSOR
stmt.execute();
resultSetPage2= ((OracleCallableStatement)stmt).getCursor(4);

but this way it will fetch all records in one short and put in resultset.This table is huge and i want to restrict number of rows to be fetched.
kindly help me with exapmple.

Open does not fetch anything.
You fetch when you call the fetch/next procedure on the result set.

No.
It contains the number of rows you defined with setRowPrefetch procedure.

Reason Hi, I am new to OAF. I have to do a similar thing. Like I have to call a procedure in which a record variable(of %rowtype)or a refcursor has to be passed as one of the parameter(it is of IN/OUT type). I am using JDeveloper 9.0.3. Can you please tell me how to do that as I am totally stuck there. Thanks

Don't report your question, post it in the topic.

Regards
Michel
