All,

My current application is written in VB accessing the Oracle back-end. I have just been asked about how to execute a query that may return many thousands of rows, but only display, let's say, 1000 at a time. After the first set of rows was returned, the user would click a button and request the next thousand.

We are currently using reference cursors and everything is working well. I was wondering if anyone has done something like this, and how did you do it? I could see using an inline view and re-executing the query every time and selecting the range of records to return. Storing the result set in a temporary/rollup table might also work. I obviously would need to clear this table out every night.

Any other ideas?

thanks
