Tom Lane	a9545b3aef	Improve UPDATE/DELETE WHERE CURRENT OF so that they can be used from plpgsql ... with a plpgsql-defined cursor. The underlying mechanism for this is that the main SQL engine will now take "WHERE CURRENT OF $n" where $n is a refcursor parameter. Not sure if we should document that fact or consider it an implementation detail. Per discussion with Pavel Stehule.	2007-06-11 22:22:42 +00:00
Tom Lane	6808f1b1de	Support UPDATE/DELETE WHERE CURRENT OF cursor_name, per SQL standard. ... Along the way, allow FOR UPDATE in non-WITH-HOLD cursors; there may once have been a reason to disallow that, but it seems to work now, and it's really rather necessary if you want to select a row via a cursor and then update it in a concurrent-safe fashion. Original patch by Arul Shaji, rather heavily editorialized by Tom Lane.	2007-06-11 01:16:30 +00:00
