Limiting large view object query result sets
In the recipe Limiting the rows fetched by a view object in this chapter, we have seen how to limit the number of rows that can be fetched from the database by a view object. While this technique limits the number of rows fetched from the database to the middle layer, it will not limit the view object query that runs in the database.
