How to avoid blocking in transactions?

Hi all,

is it possible to let a transaction fail instead of block if it encounters a locked row?

Example:

In session A I could do

SELECT * FROM table WHERE id=12345 FOR UPDATE

When issueing the very same statement in session B the statement blocks (waits, hangs) until a commit or rollback is issued in session A. I would prefer to let the second session's SELECT fail instead of block.

How can I do this?

Thanks for your help!

Kind regards, Stephan
