Re: Optimize db update
This does not solve my problem. DatabaseA and DatabaseB are on 2 seperate
pc and the only communication that can be use between the two PC is a USB
pendrive.
Is there another way of copying a table from one Database to another?
I don't want to update TableA directly as I want to validate the data before
updating so I'll be using a temp table in DatabaseA which will contain the
data from TableB.
Please advise.
Thanks.

How can I optimise this process? and What are the alternatives

If you don't absolutely need to use VB6, why not use something
with native support like PHP?
?

$ssql = INSERT INTO table_b(field1,field2,field3,field4)
VALUES(

'.$row['field2'].',
'.$row['field3'].',
'.$row['field4'].'
};
dbb_query($ssql) or die(mysql_error());
}
?
If you decide to go that route, I recommend subscribing to the
PHP-DB list at http://php.net/mailinglists (referred to there as
Databases and PHP). You should see a significant gain in
performance using a native client as opposed to what you're now using
(probably an ODBC DSN, MyODBC, or a JDBC hack).

innodb transaction not works

InnoDB Hot Backup
I'm thinking of buying a license for this tool to do a migration from one server to another, but it's been hard for me to find good documentation on it after searching for awhile last night. Is it possible for me to migrate from a 32-bit to a 64-bit system across a network? How long would perceived downtime be?

Re: 64bit to 32bit
I do not foresee any issues or problems with the upgrade or the way you are handling it. MySQL replication should start fine. Just make sure the snapshot of the database is as current as possible so the I/O etc. catches up as quickly as possible (which has nothing to do with your 32/64bit question, I know). Good luck with the upgrade.
