Hi Mark
I would appreciate if we can define Under_extreme_conditions as you
have mentioned in this link below
http://archives.neohapsis.com/archives/mysql/2005-q3/0163.html
I would appreciate if you can give us a workaround for this, which
can eliminate this set autocommit =1 command being

Hi
Yes, you can set the variabe per-connection.

Check with two connections. For Transaction safe engines(such as InnoDB, BDB,
or NDB Cluster),to disable autocommit mode for a single series of statements,
use the START TRANSACTION or BEGIN statement. W
Thanks!
I played a bit init_connect. I'm not sure though how can I verify the
autocommit value. You say 'by select'. Something like this?
select @@AUTOCOMMIT;
Because that still gives me a value of '1'.
More important to me: Can this variable be set per-connection? If s
There is no global system variable to set Autocommit; but we can achieve the
same with 'init_connect=SET AUTOCOMMIT=0'.
This variable can be set from the mysql or in the commandline or in the
option file.
Like,
mysql > SET GLOBAL init_connect='SET AUTOCOMMIT=0';
or

I've confirmed that this does affect ALL incoming connections.

If you are using AUTOCOMMIT=1 then the COMMIT should not be necessary.
