Hi all,
I'm trying SELECT FOR UPDATE
but I have a problem with locks.
example:
I have two users accessing to the same records, say...
user1:
DELECT * FROM table WHERE field=value FOR UPDATE
---------------------------------------------------------------------------
user2:
DELECT * FROM table WHERE field=value FOR UPDATE
at this point user2 can't do nothing except waiting for user1 unlock recors.
My question is:
- Is it possible to know in advance if the records of a given query are
locked, to prevent to be locked for ever?
Thank for any help,
Jose Soares
