How do I limit the number of rows retrieved at a time using RefCursor?
I have a PL/SQL package in use, that returns a REF CURSOR. This is currently being used in a Forms 6i application. Now I want to develop an ASP.NET web application that displays exactly the same information as my Forms 6i module. In fact those two applications will be used concurrently for a while.
I looked at the sample code provided on otn.oracle.com and decided to use the OracleDataAdapter.Fill()-method to fill a dataset and bind that dataset to a pageable GridView. Now I wonder, whether this method retrieves ALL records of the query at once and how I can limit the number of rows fetched? The Select statement retrieves up to 10000 rows at a time. Most of the time, a user is only interested in the first 20-30 rows. Forms 6i fetches more rows as the user scrolls down, how can I implement the same behavior in ODP.NET?
