Hi all,
I made a question several days before to describe my strange trouble of
mysqldump. But I still can't figour it out. Well, I just want to ask
another question whether I could just backup my databases by copying
the data folder to some place? Then if I meet some disaster, could I
just copy the backup folder back to recover my...

I am in the process at looking into load balancing 2 web servers.
I will need both servers to have MySQL server installed and then a load
balancer to split the traffic to both servers.
The servers will be running apache with PHP web sites.

I am thinking about implementing replication. Basic question is what
kind of delay there would be to have the data replicated. Not a
massive table, and all on the same net.
Furthere, can you specify priority for replication?

I'm running 5.0.4-beta with replication, and it works OK. Except...
When I use "create function" in the master, it does not get propagated
to the slave. Is this reasonable behavior? I don't think so. I'm
supposing it is a bug.
Any comments?

Hi,
What is the real difference between LEFT JOIN and RIGHT JOIN?
Are there situations where a query with RIGHT JOIN cannot
be rewritten with LEFT JOIN and tables reversed? (and vice versa).
In MySQL documentation there is stated explicitly:
"RIGHT JOIN is implemented analogously to LEFT JOIN, with the roles of
the tables reversed."

Some one suggested me to alter my tables to InnoDB instead of myISAM
type to improve speed for select queries. Is this really true. I read
some article that stated that myISAM was optimized for select queries
over update/insert because of most of the queries for web based
applications are select queries.
Can anyone tell me what the...

I'm wondering if there's any way to speed up create table queries?
Besides upgrading hardware, that is. The very simplest table creation
query, "create table table1 ( field1 INT(10))" is taking about .03
seconds, which compared to other queries (large inserts at .01 seconds)
and previous experience appears inordinately long. Further, it...

Can anyone recommend best practices for the fastest way to remove large
numbers of rows at once?
I am diving my deletes into chunks (1000 rows at a time) but this still is
very slow.

Does START TRANSACTION and COMMIT apply only to the Connection for which the
START TRANSACTION statement was performed? So if a second Connection is
created, and used to access different tables in the same database, are the
tables affected by the second connection visible to other processes as the
changes are made, not masked by the START...

After START TRANSACTION but before COMMIT, are intervening SQL transactions
visible to other threads or processes? I understand that failing to perform
a COMMIT, or explicitly performing a ROLLBACK, results in the transactions
occurring after START TRANSACTION being undone. But until and if the

Hello!
I need to backup a MySQL database (MySQL 4.0). But it is on a
shared-hosting web server and so I don't have direct server access. I

How can I backup the database? I think it is possible with PHP
