It does, or at least a query written to work the same way works fine for
me. Not only that, but at least in the presence of a unique index the
query planner optimises it to the same quer

I think what you want is something like

where id = 2 ) as foundrow where id = 1 ;
UPDATE 1
Thinking about it, it'd actually be better written as:
UPDATE x SET val = foundrow.val FROM ( SELECT val FROM x AS x2 WHERE
x2.id = 2 ) AS foundrow WHERE id = 1;

Hi Everyone,
I want to thank everyone for their help / suggestions...
I really appreciate it.
Though I think I have found a winner.

UPDATE 1
Very elegant, very clean...
Very nice!

Maybe you should use FROM clause in the update that references a
row-valued subquery?

HI Gurjeet,
You're right.
But what information do you need to know?
The copy is inside the same table, so I don't understand why it (the
required query ) would require any joins.
Ie. I want to copy the contents of a row (but for the id column - of

Hi Everyone,
I have asked our DBA at work and h is not too sure either... so I
thought it best to on the list.
Basically, what I am after is a way to copy the contents of one record

This should work --- in PG 8.1 or later. In older versions you'd have
to fool around with a FOR ... IN EXECUTE ... loop.

Hello Adrian,
Here is my execute string,
