Christophe,
It's not clear why you need to do it this way, though. Presumably, since
you did some kind of computation that came up with the number '4', you
can assign that value instead of using the field a:
UPDATE test1 set a=4, b=4;
There are two reasons:
1. In my case b expression ne

differently.

Anyone have any ideas/suggestions on how to model siblings in a database
so that it is possible to eg. only send letters to the parents once. In
this scenario each sibling has the contact parents input separately

Hi,
I have a function that returns a refcursor that I need to call from a
second function. In the second function, I'd like to read a column
value from each row. However, I'm having a problem accessing the rows
of the refcursor.
Can anyone point me to a working example of how to pull this off?

Ok, but this is really my problem: I cannot perform an ALTER TABLE with the
system in production mode, because the ALTER TABLE hangs due an
AccessShareLock.
We use two-tier mode, so is it necessary to shutdown all users before
perform an ALTER TABLE? Is it this true?

Hmm.. That does look very interesting. The only thing that concerns me
is where it says it supports "Basic Queries (Extended queries not yet
supported)". I'm not sure what is meant by "Extended queries". Any idea?
Thank you for the pointer, Filip. I'll check it out.

The select is just "select * from controle". The connection is JDBC and the

What am I doing wrong?
This is the code:

Tsung [http://tsung.erlang-projects.org/] has a nice pg proxy module. It
records your "query stream" and is able to replay it later.
