They will only fire with client cursors. That is, when you fetch the data to a local memory buffer. If you're fetching a lot of data, it'll be slow because of the memory required to store it. By contrast, using a server cursor is pretty fast, since only those records which are "visible" by some means will need to be in memory at any given time. So, you have to choose between slow and memory hungry, with fetch progress, or relatively fast and lean, with no fetch progress. -- - Mike Remove 'spambegone.net' and reverse to send e-mail.
