Is it possible to do a nonblocking lock? That is,
I want several clients to execute,
begin
if table A is locked
then
go around doing stuff on other tables
else
lock A and do stuff on A
endif
the problem is, if I use normal lock, then
after one client has locked and is doing stuff on A
the other one will block and thus it won't be able
to go around doing stuff on other tables. Is it
possible to do a nonblocking lock that will just
fail if the table is locked already?
Thank you
