Currently there are FETCH and the (non standard) MOVE commands to work on cursors.
(I use cursors to display large datasets in a page-wise way, where the user can move per-page, or, when displaying a single record, per record. When the user goes back from per-record view to page-view, I have to restore the cursor to the position it was on before the user changed to per-record view.) I have to "manually" keep track of the cursor position, but in some cases it would definitely be easier to just query the current cursor position directly from the database and later use "MOVE ABSOLUTE" to rewind it to that position. That could be achieved e.g. by a hypothetical "TELL <cursor-name>" command. It does, however, not exist and I have not found an alternative. Is there a way to query the current cusros position at all? If not, does a TELL command sound like a good or bad idea? -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
