Dear all,
Today I need to write the output of an postgres table into XML format.
I think there is an easiest way to do this but not able to find it.
In mysql there is simple query for that :
mysql -X -e select * from db_name.master /hdd2-1/test.xml

Hi, would it be possible to implement a *nowait *modifier to the
*update*statement in order to tell it not to wait and raise an error
-just like a
select for update nowait would-, instead of defaulting to waiting forever
until the lock becomes available?
The lack of such a modifier nowadays

Hello Chris, yes that does seem to be a lot cleaner - though it does one
thing that is not right -
ie)
add to the previous data
insert into modvalues (parties,baloons,color,dayofpurchase,amountpur)
values
('1','big','red','1/2/2011',4);
then the output looks like:
baloons colorjan

yeah -- but you only need to block selects if you are selecting in the

are doing:
begin;
lock table foo exclusive;
insert into foo select ... where ...;
commit;
is good enough. btw

Don't you have to block SELECTs so that the SELECTs get serialized?
Otherwise concurrent SELECTs can occur at the same time, find no existing
rows, then all the inserts proceed and you get errors (or dupes).
That's how Postgresql still works

Well, yes. OTOH, if you want to use upsert and you have to use

Nice.
Much more maintainable IMO and quite close to what I was looking for.
Thanks a lot for the suggestion, I will definitely try it/implement it right
away.
Still has some redundancy compared to an hypothetical nowait modifier but I
think it's the very best alternative so far.
