Hi!
I have a table called "tbltest". There i want to avoid multiple updates at
the same time. so i tried to use the transaction method.
transaction 1 transaction 2
BEGIN;
SET TRANSACTION ISOLATION LEVEL
SERIALIZABLE;
SELECT * FROM tbltest WHERE id=0
FOR UPDATE;
UPDATE
tbltest SET col1='test' WHERE id=0;
The update statement (transaction 2) waits, until i commited the transaction
1. How can i avoid this waiting? is it possible to get an error like "ERROR:
id 0 is currently not available" - or somethink like this :-)
Thanks!!!
Michael
