RE: 2 questions about Replication
You could daisy chain the servers together, this would be ineffiecient and not robust, but it would work. shop1 master to shop2 | customers1 | V shop2 master to shop3 | customers1 customers2 | V shop3 master to office | customers1 customers2 customers2 | V head office Alternatively, if this is just for backup purposes I would write a script that dumps the customers table at each shop, compress it and then ftp it to head office every night.

MySQL only supports one master and many slaves. As I saw in comments at: http://dev.mysql.com/doc/mysql/en/Replication_Options.html You may use replicate-rewrite-db for tables: replicate-rewrite-db = RemoteTableName -LocalTableName i have 2 questions about Replication. 1) I managed to make one slave and one master. The replication works fine and it updates only one table from one database (cause of the replicate-do-table=db.table1). The first question is can I tell mysql that table1 from master to be named table2 on slave? I already have another table1 and I dont want to overwrite it. 2) As far as I read I can have as many slaves as I want and one master. Can I have the opposite? Imagine the follow scenario: I have 3 Shops with 3 Database (same structure) and they all contain a table CUSTOMERS. I want to put all those customers from 3 shops to a central database. So, I was thinking to inverse the master/slave logic and backup each shop to the slave computer. Thats why I need to change the name of table. Because i want to backup customers of first shop to CUSTOMERS1, customers of second shop to CUSTOMERS2 etc etc. Nikos [EMAIL PROTECTED] wrote: -- For technical support contracts, goto https://order.mysql.com/?ref=ensita This email is sponsored by Ensita.NET http://www.ensita.net/ __ ___ ___ __ / |/ /_ __/ __/ __ \/ /Gleb Paharenko / /|_/ / // /\ \/ /_/ / /__ [EMAIL PROTECTED] /_/ /_/\_, /___/\___\_\___/ MySQL AB / Ensita.NET ___/ www.mysql.com -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED] -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
RE: Sequencial Replication
As I understand it... The SQL must be executed in sequence, otherwise you'll end up with incosistency between master and slave. an example: If thread 1 is inserting data, and thread 2 is running updates based on the inserted data then you could end up with different results on the slave than on the master. I'm sure someone else could explain it better.. or possibly correctly :) Chris -Original Message- From: Arvind Gangal [mailto:[EMAIL PROTECTED] Sent: 10 November 2004 10:28 To: 'Gleb Paharenko'; [EMAIL PROTECTED] Subject: RE: Sequencial Replication Hello, I understand that the slave executes the sqls from binlog in sequence, but are there any plans to make it multi-threaded so that it executes multiple sqls from binlog.

RE: enum TRUE/FALSE
If you want an enum to have the possible values of NULL or 1
alter table `Associate` modify `Active` enum('1');
from the mysql manual
http://dev.mysql.com/doc/mysql/en/ENUM.html
If an ENUM column is declared to allow NULL, the NULL value is a legal
value for the column, and the default value is NULL. If an ENUM column
is declared NOT NULL, its default value is the first element of the list
of allowed values.
If you simply want a column to hold boolean data I prefer to use
tiyint(1) unsigned not null
In my application I then treat 0 as False and 1 (or any other number) as
True
I do not believe you can make mysql evaluate NULL to be False, mysql
will evaluate 1 = True and 0 = False,
TRUE And FALSE are simply aliases for 1 and 0
you have two options
1) You could simply update your table
alter table `Associate` modify `Active` enum('0','1');
(or 1 then 0 if you want true to be the default)
then
update `Associate` set `Active` = 0 where isNull(Active);
2) modify your queries
select count(*) from Associate where Active!=1 OR isNull(Active);
select count(*) from Associate where Active=1;

Optimize query help
Hi,
We log all sessions on our webserver to a table, and then periodically run a
batch process to analyze the visitors ip addresses to determine the
city/region/country of origin.
we use MySQL 4.1.1-alpha-standard-log on Redhat AS, installed from the mysql
RPM.
The query below takes about 1 second to run, which is fine on its own, but
it has to be run for 35+ locations.
I *think* I've created all possible indexes to speed this up, but if anyone
could help it would be much appreciated.
cheers, chris

RE: Storing foreign characters in DB

(I have MySQL 3.23.58 running). I'm not how sure how these characters are being stored in the MySQL database, but, when I retrieve the text and run it through PHP's htmlentities() function, each foreign character is converted into 2 other foreign characters that don't at all represent the original. For example, a lowercase u with an umlat over it (ΓΌ) is somehow displayed as an uppercase A with an umlat over it followed by the 1/4 symbol after parsed by htmlentities(). A lowercase o with an ulmat displays as an uppercase A with an umlat over it followed by the paragraph symbol. It seems that the uppercase A w/umlat is a constant, and the next character changes. How are these foreign characters being stored in the DB? Do I need to do something in order to store these characters properly, or is this something I need to somehow do on the PHP side of things??
