We tried it on blank server with only 1 site hosted. the server specs were 1 GB RAM Xeon Dual Processor 100 GB HDD but same, a blank serevr was also choked by the usage. This started happening bcz.

Re: Auto Generation Of Passwords
think this will work, have not tried it: char(int) returns a character rand() returns a random number between 0 and 1 (with loads of decimal places) round(int) rounds a number to a whole number. so a random password generator could be SELECT char(round(rand()*100), round(rand()*100), round(rand()*100), round(rand()*100), round(rand()*100)) maybe stick some round(rand()*100)) at the end to add some numbers to your password. the char() will return some special characters ;'£$ etc... so you will h ave to find what range they are in and adjust the rand()*100 part maybe if they are all in the low range you can do (rand()*100+10) I bet someone says there is a function like randompassword() now :| -- Dave - Original Message - From: Michael Mason To: 'MySQL Mailing List' Sent: Tuesday, July 13, 2004 1:25 AM Subject: Auto Generation Of Passwords I was wondering if it's possible to create a field in a MySQL Databse that automatically creates unique field values for use as a password for example Michael Mason Business Support Services Arras® People Tel: 01706 342310 Mobile: 07793 782287 Fax: 01706 642754 Member of the Recruitment Employment Confederation (00052055) The views expressed in this mail are entirely those of the sender, and do not necessarily represent the views or position of Arras Services Ltd.

join only works fine in number column?

SET PASSWORD = PASSWORD('newpassword') does not work if user has host extension

database with a host extension ([EMAIL PROTECTED], for example), the SET
PASSWORD command fails with the message Can't find any matching row in the
user table.
For security reasons, I need the users to be defined with a host extension.
Is this a bug, or is there a way around this?

Hi! On Jul 12, Hickey,Thom wrote: I've been comparing the performance of 4.1 with the MySQL 3.23.58 that came with our Rocks cluster software.

The database is fairly large with about 3 gig spread over a half-dozen tables. The largest table has 62 million rows. What kind of queires do you run ? What does EXPLAIN show ? Are all tables ANALYZE'd ? 4.1 can use more complex query transformations and join methods that should bring more performance. Of course if the statistical data are incorrect, the optimizer cannot jugde what is more and what it less, so new features may expose problems that were hidden in the old version.

When that user does a select user() are they receiving the numeric ip
address or the dns resolved name? If you set up the privilege with the
numeric ip and dns is resolving this the two values will not match. If
necessary you can use --skip-name-resolve.

Re: Implementing full text searching - need recommendations
Hi, you can try to add your headings to the stopword list, but remember: - A word is any sequence of characters consisting of letters, digits, `'', and `_'. Any word that is present in the stopword list or is just too short is ignored. - The stopword list is global and will affect all tables. As for me, in your situation I would prefer another aproach distributing your text to several TEXT columns. Then your headers become column names.

Re: Sql Query Issue
I suggest that you add more indexes to your tables. If you run an EXPLAIN on your query, you will see that you are doing WAY too many table scans and that is what is slowing you down. Index the columns in each table that reference the ID values of another table. Then run your EXPLAIN again and you should see a major difference. Use the manual, it has great advice on optimizing queries and full documentation of the EXPLAIN command.

RE: SET PASSWORD = PASSWORD('newpassword') does not work if user has host extension
Right on!
Effectively, user() returns the dns resolved name. So obviously this will
not match the mysql user table entry, where the ip range is specified.
I will try the --skip-name-resolve option, but I have to wait for a
scheduled down time of the server.
Thanks for the expert advice!

When that user does a select user() are they receiving the numeric ip

Subject: SET PASSWORD = PASSWORD('newpassword') does not work if user has
host extension
I am using MySQL 4.0.18 on Windows.
I want to give my users the possibility to change their MySQL password
after
they log in.
The command SET PASSWORD = PASSWORD('newpassword') works fine as long as
the
user has been created with no specific host extension in the mysql
database
(corresponding to e.g. [EMAIL PROTECTED]). Now if the user is defined in the
mysql
database with a host extension ([EMAIL PROTECTED], for example), the
SET
PASSWORD command fails with the message Can't find any matching row in
the
user table.
For security reasons, I need the users to be defined with a host
extension.
Is this a bug, or is there a way around this?
(Please do not suggest to use SET PASSWORD FOR [EMAIL PROTECTED] =
PASSWORD
('newpassword') as this is only allowed for users that have access to
the mysql
database!)

Re: Replication - multiple masters
Having that many instances on one box is going to be a management nightmare. I can only imagine the recovery scenarios should you have a hardware problem. Perhaps you may want to think about writing your metric data to a local mysql instance then pulling the data from each instance into the depot database with a script that runs every few minutes. Using this pull methodology you don't have to worry about losing metrics if your depot is down but you don't have the burden of up to tweleve databases to manage on one machine (twenty four databases total). Another option would be to write the metrics to a flat file on the web server, then simply serve that file up via HTTP. You then have only one database to manage, you can pull the metrics into it very easily and you still don't have to worry about a down depot server. In your depot you then have a couple options. You could have one master table that contains metrics from all the machines and contains a column for the machine name or you could have a seperate table for each machine, and if you want to examine metrics for all machines you could use a merge table. --- Marc Knoop [EMAIL PROTECTED] wrote: Jeremy Zawodny writes: The web servers record web metrics to local mysql databases.

Jeremy - good to hear. Now that I know this is technically possible, which of the following possible solutions would be the cleanest or most efficient from a management perspective: 1) Use mysql replication to have mirror dbs on the DEPOT server. A job would regularly run on DEPOT to consolidate all data into one db so that an external system can query/report on. 2) Do not use mysql replication and instead have a job on DEPOT regularly pull from each webserver and consolidate all data into one db so that an external system can query/report on. 3) Same as #2, except the web servers would *push* to DEPOT instead of being *pulled* from. As another reader commented, #1 could be difficult to manage because of the number of DBs (N*2). Plus, DEPOT is already a master to all web servers for read only data. #2 and #3 seem to be more appropriate, as long as the jobs are FAST and can be managed. Would Perl be the ideal candidate for this? Since the web servers are remote, performance of DEPOT updates is important - something replication was good at. It's nice to have different solutions to this puzzle.

Access hosts wildcard.
Hi, I'm setting up MySQL databases on 'shared server' space I've rented using cPanel's 'MySQL Database' interface. I can add 'access hosts' (it's not limited to localhost) and it says the % wildcard is allowed. Forgive me if this is a trivial or annoying question (I can't find the answer anywhere) but how do I just 'allow any host'? Presumably I use % in some way maybe '%.%.%.%' (an all encompassing IP address with wildcards instead of numbers) or maybe it's just '%'?

Other databases (Oracle) generate an error when you

Oracle would require you to do:

But there are 2 rows with that email which, considering 'email' is the
only thing group'ed on, makes sense. From the link above, one would
only select 'first' and 'last' if they knew they were unique as well and
wanted to save on typing. Probably the only way to trust that is to
have a unique constraint on those three columns.
Oracle would require you to do:

Yah, and Oracle actually enforces foreign keys and won't insert guessed

Oracle 2 MySQL updates/replication?
Hello, I found a question about Oracle 2 MySQL replication in the archive on Sep. 2001 but no mention since? We have a department using Oracle 8.1.7 and I'm running MySQL 4.0 and neither of us wants to change :-) I could call a Perl, C++ or Java program from cron to periodically update the MySQL instance from Oracle but was hoping to use a trigger/stored procedure to initiate the update so it seems more real time. Does this seem possible? Of course it may turn out non-trivial to write the synchronization code so I'll take suggestions on that front also.

Re: Oracle 2 MySQL updates/replication?
An option would be a log reader program that uses Oracle log miner to only show commited transactions from the redo logs. You could then replay the SQL that is being executed on the oracle box on the mysql server as long as the tables are defined the same. 9i has an enhanced log miner that can be used to read 8i redo logs as well, so you might want to use the newer 9i client if you go this way. Updates to the oracle database could be processed the same way using the mysql binary log as long as no mysql extensions were used like inserting multiple rows with a single insert statement. --- Jeremy Zawodny [EMAIL PROTECTED] wrote: On Tue, Jul 13, 2004 at 06:11:22PM -0700, Carl Edwards wrote: Hello, I found a question about Oracle 2 MySQL replication in the archive on Sep. 2001 but no mention since?

Luckly this is not a production server...
EXPLAIN SELECT tb_test1.id
FROM tb_test1, tb_test2
WHERE tb_test1.id='abcde'
AND tb_test1.id = tb_test2.id
In Extra show: Impossible WHERE noticed after reading const tables
I also found out that the trim should actually go to the 'matching' id:
/* Previously I suggest trim on the left column: */
SELECT tb_test1.id
FROM tb_test1, tb_test2
WHERE tb_test1.id='abcde'
AND TRIM(tb_test1.id) = tb_test2.id
/* However, this works as well, and it seems more logical? */
SELECT tb_test1.id
FROM tb_test1, tb_test2
WHERE TRIM(tb_test1.id)='abcde'
AND tb_test1.id = tb_test2.id
Anybody could explain this?
Thank you.
Francis

Have you tried this with the latest MySQL 4.1.x build? Does it not work in
this version? What does the explain plan show?

Subject: Cannot do join on varchar
Hi,
I found out that when joining varchar column, you have to trim down
the
left column in order for MYSQL to match the row, is it a known issue?
Or
join only works fine in number column?
CREATE TABLE `tb_test1` (
`id` varchar(5) NOT NULL default '',
`name` varchar(100) NOT NULL default '',
) TYPE=MyISAM DEFAULT CHARSET= utf8;
CREATE TABLE `tb_test2` (
`id` varchar(5) NOT NULL default '',
`name` varchar(100) NOT NULL default '',
) TYPE=MyISAM DEFAULT CHARSET= utf8;
INSERT INTO tb_test1(id, name)
VALUES('abcde', 'NAME1')
INSERT INTO tb_test2(id, name)
VALUES('abcde', 'NAME2')
/* The following display zero row */
SELECT tb_test1.id
FROM tb_test1, tb_test2
WHERE tb_test1.id='abcde'
AND tb_test1.id = tb_test2.id
/* The following will display correct result */
SELECT tb_test1.id
FROM tb_test1, tb_test2
WHERE tb_test1.id='abcde'
AND TRIM(tb_test1.id) = tb_test2.id
Redhat 9, with MYSQL 4.1.1, using UTF8 as default charset.
Any idea?? Thank you.

'x' on blob field when retrieving records
I have a query like this
select hex(blob_field) as myField from table
When the blob field is empty ('') it returns 'x'.
i'm using ADO with Visual Basic and MyODBC 3.51.
MySQL Version is 4.0.18 and SO is Win XP Pro (also happens on Windows 2K)

How to fix a connection of replication
Hello,
Is there any way to fix a connection of replication
from slave host when user on slave host noticed
that the connection of replication had been lost?
Now I have a following environment.
MySQL Master server == replication == MySQL Slave server
Both server has
Turbo Linux 8.0 WS
MySQL-4.0.18.
Master has a global IP address and has good network performance.
Slave is connected to Internet with 64kbps.
By a network problem, the connection between slave server
and Internet often drops.
So I want to make a command like mysql_synchronize which
tries to fix the connection of replication immediately.
I think that a possible script for the command is like
mysql --host=master_host -e show master status
# memory master_log_pos and master_log_file
mysql --host=slave_host -e \
stop slave; start slave; select master_pos_wait('master_log_file',master_log_pos);
Are there any better script?
Now I am using following parameters (these are default values).
slave_net_timeout=3600
master-connect-retry=60
I think these values should be decreased in my environment.
slave_net_timeout=30
master-connect-retry=10
If I use above values, it will not be necessary to use mysql_synchronize.
But I think these values cause a wasting network traffic.
Any ideas?
Thanks,
