Hi List,
Let's suppose I have these two tables:

`Key` varchar(25) collate latin1_general_cs NOT NULL default '',
`Table` varchar(25) collate latin1_general_cs NOT NULL default '',
`Value` text collate

The idea is to have a audit trail to record the changes made. So, I want to
insert a new record in the staff table and right after this, insert a

Thanks Mike.
I understand the possible gaps that I might have if I use the ROLLBACK.
This is acceptable in my case.
What I really want to avoid is what I am doing now: open one transaction to
insert, or update, or delete certain information and close with the commit.

Thanks for all your help Mike.
Problem solved. I divided to process in two parts: one write the
insert/update/delete and then write the changes in the audit trail. All this
inside one transaction. If the first part fails, ROLLBACK. If the second
part fails, ROLLBACK, otherwise, if both were done
Greetings,
I created a table during transaction and was surprised to find out it
still existed after I did a ROLLBACK. The same seems to apply to changes
made using ALTER TABLE statements.
Is there a simple logical explanation to this behaviour?
Any help would be appreciated.

Victor,
Thanks for your reply
Hi,
I would like to migrate my DB from Sybase ASE to MySQL INNODB table. Data has been
extracted and stored as a file. I want to use the command Load Data Infile to insert
the data to MySQL. However, some table contains millions of rows. Can i control the
batch size of the loading (e.g.
I do not believe this is currently an option in the `load data infile`
syntax. One option would be to read the file programmatically and issue the
commits after `x` number of inserts.
