MySQL
Hola de nuevo, ahi va otra consulta de MySQL Quisiera que una de mis columnas no tuviera valores repetidos, con lo cual creo que deberia utilizar UNIQUE, y a la vez esta columna no pueda ser nula en función del valor de otra columna. ¿Existe alguna posibilidad? Me explico, tengo dos columnas, una 'tipo de usuario' y otra 'numero de habitacion'. Si el tipo de usuario es '1', el numero de habirtacion puede estar vacio, o mejor dicho, deberia estarlo. Si el tipo de usuario es '2', el numero de habitacion debe estar cumplimentado. Gracias ___ Yahoo!

He esta leyendo algunos documentos acerca de el soporte de claves foraneas y he visto que para ello dicha versión necesita un patch llamado MySQL-MAX. En la sección de downloads he visto que existe la versión 3.23.54-MAX, ¿es este el patch necesario? No. Por favor leya las explicaciones que expongo abajo. En tal caso he visto que no es ningun archivo instalable, sino que en su interior hay carpetas llamadas como lib, include, bin... ¿Qué debo hacer con ellas, copiarlas sobre la carpeta de MySQL y rearrancar el servidor?. En nuestra sección de download, existen dos tipos: el que ya está listo para usarlo directamente y el llamado source que necesita ser compilado para usarlo, este último generalmente es usado por programadores que tienen el compilador VC++. Tu tienes que usar la versión que es denominada: mysql-3.23.54-win.zip nota que la versión source es denominada: mysql-3.23.54-win-src.zip. Descompacta el archivo en un directorio temporario y rueda el archivo setup.exe. Recomiendo que lo instales en el directorio patrón c:\mysql. Abre una tela DOS y vá al directorio c:\mysql. Alli tu encuentras unos archivos con una extensión .cnf. Esos archivos sirven para usarlo como ejemplo para tú hacer el archivo de configuración my.ini. Entonces puedes hacer una cópia de la siguiente manera: copy my-medium.cnf c:\windows\my.ini ó de acuerdo con tu sistema operativo: copy my-medium.cnf c:\winnt\my.ini luego, en el mismo lugar: edit c:\windows\my.ini Remueve los # de las siguientes claves bajo la sección [mysqld] basedir=c:/mysql datadir=c:/mysql/data innodb_data_file_path = ibdata1:400M innodb_data_home_dir = c:\ibdata innodb_log_group_home_dir = c:\iblogs innodb_log_arch_dir = c:\iblogs set-variable = innodb_mirrored_log_groups=1 set-variable = innodb_log_files_in_group=3 set-variable = innodb_log_file_size=5M set-variable = innodb_log_buffer_size=8M innodb_flush_log_at_trx_commit=1 innodb_log_archive=0 set-variable = innodb_buffer_pool_size=16M set-variable = innodb_additional_mem_pool_size=2M set-variable = innodb_file_io_threads=4 set-variable = innodb_lock_wait_timeout=50 ---final del archivo my.ini--- Ahora crea 2 directorios: mkdir c:\ibdata mkdir c:\iblogs Como tu puedes notar para tener las claves extranjeras tu necesitas usar el tipo de tabla llamada InnoDB. También nota que arriba existen valores de memoria y tamaño de archivos que tu puedes adaptar a los recursos que tu computadora tiene o a tus necesidades. Estando lo de arriba listo, tu necesitas ahora arrancar un servidor MySQL del tipo MAX. Cambia para el directorio llamado c:\mysql\bin y verifica que existan los servidores abajo relacionado: mysqld-max.exe (para usarlo en Windows 9x o ME) mysqld-max-nt.exe (para usarlo en NT/Win2000/WIn XP) Ahora arranca el servidor con el comando: c:\mysql\binmysqld-max-nt --standalone --console y tu verás que InnoDB muestra lo abajo: InnoDB: The first specified data file C:\ibdata\ibdata did not exist: InnoDB: a new database to be created! 030113 6:29:14 InnoDB: Setting file C:\ibdata\ibdata size to 51 MB InnoDB: Database physically writes the file full: wait... 030113 6:29:19 InnoDB: Log file C:\iblogs\ib_logfile0 did not exist: new to be created InnoDB: Setting log file C:\iblogs\ib_logfile0 size to 16 MB InnoDB: Database physically writes the file full: wait... 030113 6:29:21 InnoDB: Log file C:\iblogs\ib_logfile1 did not exist: new to be created InnoDB: Setting log file C:\iblogs\ib_logfile1 size to 16 MB InnoDB: Database physically writes the file full: wait... 030113 6:29:23 InnoDB: Log file C:\iblogs\ib_logfile2 did not exist: new to be created InnoDB: Setting log file C:\iblogs\ib_logfile2 size to 16 MB InnoDB: Database physically writes the file full: wait...

Re: MySQL on large server
This is what I have in /etc/my.cnf on my current MySQL server (dual
AthlonMP,2GB RAM)
[mysqld]
port = 3306
socket = /tmp/mysql.sock
skip-locking
log-slow-queries = slowqueries.log
set-variable = key_buffer=256M
set-variable = max_allowed_packet=1M
set-variable = table_cache=1024
set-variable = sort_buffer=2M
set-variable = record_buffer=2M
set-variable = thread_cache=24
set-variable= max_connections=510
set-variable = thread_concurrency=16
set-variable = myisam_sort_buffer_size=64M
set-variable= tmp_table_size=128M
set-variable = wait_timeout=90
Whilst monitoring the server using 'mytop' is can see the server using
between 250 400 threads, never dropping below 210 threads ('top' reports
about 15-20MB RAM free)
'extended-status' reports: Max_used_connections = 480
And these numbers are going to grow as the server gets busier, hence the
Dual Xeon server with 6GB RAM. Instead of added more h/w in the future
though, I'd like to be able to squeeze more
out of Linux/MySQL
I used a C program (thread-limit.c) which tests the amount the threads Linux
can create (am I correct in assuming these are the same thing?) (I can send
the 4k file if required)
On my server, the program reports 255 threads max which I believe is down to
glibc...
The MySQL binaries are reported to handle 1000-1500 connections. I was
wondering if anybody has achieved this building with source? If so, what was
involved? (version of libs, etc were used?)
Possibly of relevance are the results of running 'thread-limit' against
various platforms (glibc versions were taken from 'rpm -q'; 'qpkg' in the
case of Gentoo)
Distro | kernel | glibc | threads created before
failure
Mandrake 8 | 2.4.19-16mdk | 2.2.5-16mdk| 255
Gentoo | 2.4.19-gentoo-r9 | 2.2.5-r7 | 1021
RedHat 7.2 | 2.4.19-2 (custom)| 2.2.5-42 | 255
Unfortunately, I'm not ready to deploy Gentoo on a production server, but
they're doing something differently...

Hi,

binaries in the past (not RPMs), but these have had stability/load
problems. When building from source I don't have those issues, but I
am limited by the inbuilt limits (of glibc,etc...)
How many connections do you need?
If memory serves, the master db behind Slashdot was handling around
700 connections on a 4 processor P3 Xeon with 4GB RAM. But it's been
a while since I've talked with Brian about it.
I need to build MySQL 3.23 on a production server running RedHat
7.2, patched glibc (2.2.5-42) and a custom kernel (2.4.19-2
SMP). Hardware contains Dual Xeon 2.4GHz (hyperthreading disabled)
and 6GB RAM.
With that kind of RAM and horespower you should be able to go well
above 500 connections.
I'd say more on this topic, but I've not really needed to push MySQL
in that direction. We tend to use more boxes that cost less and
replicate data.

Re: MySQL y claves foraneas
Vicente, the language on this list is English. I will try to answer your question, anyway. The patch you're speaking of is no patch, but another table handler in MySQL. Native tables are MyISAM, and MySQL has a number of alternative tables it can handle. One of them is InnoDB. In MySQL, you can use MyISAM and InnoDB together. If you need features like foreign keys, the MyISAM table handler cannot handle this (this is planned for the future, anyway). Momentarily, you will have to use InnoDB for features like this. I am not informed which operating system you use, but if it's Windows, you will find a number of MySQL servers in the bin/ directory (e.g. c:\mysql\bin). If you start mysqld, you will have no InnoDB tables activated, and thus no foreign key support. To enable InnoDB, you will have to start mysql-max (or, on NT systems, mysqld-max-nt).

Re: Problem to access MySQL via MySQLFront
The problem is with the new glibc-2.2.5-40 package released on October 3, 2002. Apparently its a known issue, and people are aware of it. The best solution I've seen so far is to role back to a previous version of this package, and its dependencies. If you are a redhat member, you have access to the errata information, as well as, the previous versions of updated binary rpms. (so you don't have to recompile anything) I downloaded glibc-2.2.5-39, and associated files.

More: What's returned from $sth-execute(); ?
Hi,
I see your point re:
Some code to illustrate:
printf Query: %s\n, $query;
my $sth = $dbh-prepare ($query);
$sth-execute();
# metadata information becomes available at this point ...
printf NUM_OF_FIELDS: %d\n, $sth-{NUM_OF_FIELDS};
print Note: query has no result set\n if $sth-{NUM_OF_FIELDS} == 0;
but what I really want to do is determine at an early stage if I have any
results at all in my result set. Actual reason for this is that I'm doing a
SELECT WHERE query and scanning my entrire DB for a session ID that
matches one read from a cookie. I then want to determine if this is a valid
session id and if not re-direct the user to a page saying unrecongnised
session id or something.
Thanks,
Jeff

problem with last_id
I have a problem with a query: I use an application where users can post messages. The messages are stored in two tables that are related by the id of the new created message. I get the last id with the following query: select max(id) as maxid from tasker_app The forum has many users and sometimes it happens that there are multiple inserts before I can receive the last id. Is it possible to stop inserts until I have finished both inserts?

RE: unexpected: 260 rows in set on a TINYINT
I would suggest appending an ORDER BY atomtype first of all. That's what I did, see original select statement: mysql select distinct atomtype from `gentradedb`.`gpatomdb` order by atomtype; You could also experiment with SELECT DISTINCT to remove any dupes from your output. Experiment how? Also, don't confuse the RANGE of values that the atomtype can be (0-255) if set to be UNSIGNED with the NUMBER OF ROWS in your output. The TINYINT is working. You have no values greater than 255 in there. You just have duplicates which gives you more rows than you were expecting I think. ;-) I don't think I do, the database has several millions rows. Thanks for pointing out the dups, isn't what select distinct is meant to do? Terry - I would suggest appending an ORDER BY atomtype first of all. I say this because if you scan your results, you have duplicates... | 165 | | 166 | | 167 | --- | 168 | | 169 | | 170 | | 171 | | 172 | | 173 | | 174 | | 175 | | 167 | --- | 175 | So you prolly have other in there too.

How can i trigger a database archive when a certain data base limit is reached in a table. Ex: when 1,00,000 records is reached, archive to file and clean table. 2. How can i restore multiple files into database ? 3.When i try to view data through my application, how can i trigger the restore the data from Archive file on demand ?

Re: let users create as much DB as they want ?

Well, we would like to do just that. Is there a way to configure mysql so that the user can create as much DB as he wants, by making sure every DB created by this user can only be accessed by him, some kind of 'root' access if you follow my logic. Furthermore, since we are billing our clients for the disk space they are using, will the structure of this will ressemble to this ; MAIN_USER - DB1 - table1, table2, ... - DB2 - table1, table2, ...

I asked the same question a little while ago and the answer given to me was this: mysql GRANT ALTER,CREATE,DELETE,DROP,INDEX,SELECT,UPDATE ON `user%`.* TO 'user'@'%' IDENTIFIED BY password; Of course you GRANT the user whatever privs you wantt hem to have, I think the only one they NEED to have is CREATE and then user will get to create any DB as long as it starts with their username, like userDB2.

Solaris Performance
Hi, I've got a mysql application that was developed on win32 and linux that is now going to be deployed on a Sun E250 Solaris 9 box with 3 36Gb non raided SCSI disks. No problem I thought - the performance is fine on my PIII 850MHz laptop, so it will rock on an E250... Not the case - the laptop seems to be performing at twice the speed of the E250 for a simple select from a table of 55 million simple rows (just 3 floating point numbers per row - the .MYD file is 700Mb and the .MYI index file is 2.7Gb). It takes 1.2 seconds on the laptop and 2.5 seconds on the sun. This is a big problem, as I have to do three of these queries plus processing and return in under 10 seconds. The laptop takes 6 seconds, the Sun takes 12. I've got a Linux PIII 933MHz Dell Server which at least half as much again faster than the laptop. I've increased the key cache to 250Mb on the Sun (it's at the default on the laptop), but no radical difference was apparent. The Sun install is pretty much out of the box, apart from the file system organisation. MySQL has its own disk. I'm running the 32 bit variants of MySQL. Would the 64 bit be any different (Solaris 9 is installed with 32 bit and 64 bit support)? Has anyone got any similar experience? Can any one recommend trying anything? Any help, comments or suggestions would be very much appreciated.

RE: PHP4 Secure connection parameters
Thank you for your responses Paul, To get MySQL4 to use OpenSSL I had to install OpenSSL 0.9.7 and modify the configure script to move my new include and lib directories to the end of the loop where it's searches for the OpenSSL files so it would see the 0.9.7 version last and therefore use it. When I tried to specify my 0.9.7 library using different variations of --with-openssl=/usr/local/ssl etc. I got many errors. As I look through the configure script I don't see how it can correctly handle an OpenSSL directory specified with --with-openssl because you really need to specify 2 dirs, one for include and one for lib. I have no idea why OpenSSL 0.9.6 didn't work for me - the manual says it should. Now I just need to understand how to connect to MySQL securely from my website using PHP from an ISP.

Furthermore, client tools report that the option local-infile is unrecognized, but the manual says it's a valid option: For the mysql command-line client, LOAD DATA LOCAL can be enabled by specifying the option -- local-infile[=1], or disabled with --local-infile=0.

Re: The diference about raw devices and disk partitions
Hi, Since you don't specify your OS, I assume you are using Linux; if you are using another UNIX like system (BSD, Solaris,...), my explanations below may be useless :( A disk partition (as /dev/sda1) is a bloc device,this is not the same as a raw device. You can get more info in Linux HOWTO: http://www.linux.org/docs/ldp/howto/SCSI-2.4-HOWTO/rawdev.html The main difference is that a bloc device is accessed through the filesystem cache while accesses to a raw device bypass the cache. However, I have not yet tried raw devices with MySQL/InnoDB, so I can't give you more MySQL specific advice.

Solaris Performance
Hi, I've got a mysql application that was developed on win32 and linux that is now going to be deployed on a Sun E250 Solaris 9 box with 3 36Gb non raided SCSI disks. No problem I thought - the performance is fine on my PIII 850MHz laptop, so it will rock on an E250...

Using tranzactions in Perl
Hi all,
I've seen the following code in MySQL cookbook:
eval
{
# move some money from one person to the other
$dbh-do (UPDATE money SET amt = amt - 6 WHERE name = 'Eve');
$dbh-do (UPDATE money SET amt = amt + 6 WHERE name = 'Ida');
# all statements succeeded; commit transaction
$dbh-commit ( );
};
if ($@) # an error occurred
{
print Transaction failed, rolling back. Error was:\n$@\n;
# roll back within eval to prevent rollback
# failure from terminating the script
eval { $dbh-rollback ( ); };
}
---
Well, I don't understand why I need to check if $@ is true or false.
If there wasn't any error, and the program should not rollback, in fact it
could give the rollback command because it won't produce any effect after
the commit command was given.
Am I wrong?

Upgrading to version 4.
In the MySQL manual, under http://www.mysql.com/doc/en/Upgrading-from-3.23.html it says: --- The old C API functions mysql_drop_db, mysql_create_db, and mysql_connect are not supported anymore, unless you compile MySQL with CFLAGS=-DUSE_OLD_FUNCTIONS. Instead of doing this, it is preferable to change the client to use the new 4.0 API. - My company's website is running version 3.23.53a, and the main client that uses MySQL is PHP 4.2.3. Will mysql_connect() no longer work in PHP? Although this manual entry is talking about the C API functions, I assume PHP uses these to communicated with MySQL. Perhaps I might be wrong, but I would like to just double check.

Re: Initiating secure connection to MySQL4 from PHP
would like to help you but I can't. This is PHP issue, not MySQL-s. SSL connections are supported by MySQL, they are also available in C API but I am not sure if and how PHP uses them. Looking up into PHP manual http://www.php.net/manual/en/ref.mysql.php won't show up needed functionality for this. You have three options: 1. Use third party tunnel (CIPE, stunnel, ssh for example) to encrypt communication. [...] I second that. If you use a local connection, IMHO there is no need to use SSL. If you use a remote connection, you would probably better succeed using stunnel (or sslwrap or some other SSL tunneling). - Cs. - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

That's true, but don't you think it's a little confusing to write

It's also an additional statement that in that case is unnecessary
to issue, so what you suggest would be less efficient.

general query log
MySQL gurus: I'm a big fan of the general query log for taking the occasional audit of activity against our database server, as well as a tool for checking on the efficiency of new (mostly PHP) projects that interact with MySQL. What I don't like is that I have to stop and restart the server process twice (once to turn the log on and once to turn it back off) in order to get the output. I've read through the documentation at mysql.com and would have searched through the list archives if I wasn't getting document contains no data messages from lists.mysql.com at the moment. We use mytop (http://jeremy.zawodny.com/mysql/mytop/) to keep some track of the queries that are being run, but the output pales in comparison (for this use) to that from the general query log. (1) Is there a way to turn logging on for brief periods (no more than 15 minutes) without having to stop and restart? (2) Is there some way to get similar output with a different tool?

Simon -Original Message- From: Andy Eastham [mailto:[EMAIL PROTECTED]] Sent: 13 January 2003 15:34 To: [EMAIL PROTECTED] Subject: Solaris Performance Hi, I've got a mysql application that was developed on win32 and linux that is now going to be deployed on a Sun E250 Solaris 9 box with 3 36Gb non raided SCSI disks. No problem I thought - the performance is fine on my PIII 850MHz laptop, so it will rock on an E250... Not the case - the laptop seems to be performing at twice the speed of the E250 for a simple select from a table of 55 million simple rows (just 3 floating point numbers per row - the .MYD file is 700Mb and the .MYI index file is 2.7Gb). It takes 1.2 seconds on the laptop and 2.5 seconds on the sun. This is a big problem, as I have to do three of these queries plus processing and return in under 10 seconds. The laptop takes 6 seconds, the Sun takes 12. I've got a Linux PIII 933MHz Dell Server which at least half as much again faster than the laptop. I've increased the key cache to 250Mb on the Sun (it's at the default on the laptop), but no radical difference was apparent. The Sun install is pretty much out of the box, apart from the file system organisation. MySQL has its own disk. I'm running the 32 bit variants of MySQL. Would the 64 bit be any different (Solaris 9 is installed with 32 bit and 64 bit support)? Has anyone got any similar experience? Can any one recommend trying anything?

Re: Embedding images stored in database
In the last episode (Jan 13), Toomas said: Hello List, Is there a simplier way to embed an image stored in BLOB field into HTML than using 2 calls to Perl scripts - one to generate HTML and another call from that HTML via IMG tag to retrieve and print image? I mean, something like you do it in a multipart e-mail message? You can actually do this with HTML as well, by using the little-used data: URI. Try copying this into a file and loading it up in a broswer: h1Demonstration of embedding GIF image directly in document/h1 This is embedded image: img src=data:image/gif;base64,R0lGODlhDwAPAJEBAL+/v/// ACH5BAEAAAEALAAPAA8AAAIujA2Zx5EC4WIgWnnq vQBJLTyhE4khaG5Wqn4tp4ErFnMY+Sll9naUfGpkFL5DAQA7 / It's not all that efficient, though, since the image is sent in base-64 and the server sends it on every page load (instead of letting the browser fetch it once and then cache it). If you're worried about the impact of launching a CGI every time you need to pull an image out of the database, see if your webserver has an SQL filesystem module, or something that will let you pull data straight out of the database without involving scripts at all. -- Dan Nelson [EMAIL PROTECTED] - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

replication - queries out of order or dropped?
Hi All, Trying my best to maintain some production servers running mysql-max-3.23.53a-pc-linux-gnu-i686 with one master and one slave. We keep having issues where we create a new table on the master, and a short while later the slave will crash because it starts trying to perform queries which insert into the new table, but it looks as if the query to create the table hasn't been executed yet (ie the table doesn't yet exist on the slave). I've got three pairs of master/slave servers, and this is happenning on all of them. My experience is that I can brute-force something such as setting the skip count to some positive integer, etc. etc., but that's only a hack, and doesn't get around the big problem here which is that somehow the queries are seemingly getting either skipped or out-of-order. Any help here? My management is getting quite upset about this. We're not using the slaves for anything at present, but they are meant to be a disaster recovery option. Right now they're worthless... Thanks in advance, David Nedved here is the output of show slave status on a currently broken slave: (sure enough the table exists on the master, but not on the slave) Welcome to the MySQL monitor.

InnoDB free: 23552 kB; (id) REFER rohit/ledger(id) It shows that foreign key has been made but i had specified it to be fk_key_1. Even if I make the Foreign Key without the keyword constraint the same thing happens ? So, what is the purpose of CONSTRAINT keyword. How can I give a name to a relationship. Also after reading the MySQL and InnoDB docs I am not able to guess how to drop a FOREIGN KEY ? How can I do that ? I am using mysql-mx-nt 3.23.54 running as a service in WinXP.

InnoDB table, NOT NULL question
Hello, I'm in the process of moving from Postgres to MySQL and I have a
question.
+How do you prevent a field from being left empty?
I have an InnoDB table that looks like the following.
CREATE TABLE `stuff` (
`stuff_id` int(11) NOT NULL auto_increment,
`somevalue1` varchar(35) NOT NULL,
`somevalue2` varchar(35) NOT NULL,
PRIMARY KEY (`stuff_id`)
) TYPE=InnoDB COMMENT='stuff table';
I run the following insert statement.
INSERT INTO stuff ( somevalue2 ) VALUES ('blah')
Now the field somevalue1 is empty. Doesn't this violate the NOT NULL
constraint on the field?
Thanks,
Gabe Geisendorfer

Re: Disable log messages for Embedded Server?
Matt,
the variable mysql_embedded makes InnoDB more silent:
heikki@hundin:~/mysql-4.0/sql grep -n mysql_embedded *.cc
ha_innodb.cc:659: if (mysql_embedded) {
ha_innodb.cc:768: srv_print_verbose_log = mysql_embedded ? 0 : 1;
mysqld.cc:390:bool mysql_embedded=0;
mysqld.cc:392:bool mysql_embedded=1;
Have you tried redirecting stderr to some file? MySQL writes most of its
messages to stderr. I am not sure if any messages come to stdout if
mysql_embedded =1. If they come, it is easy to change 4.0.x so that they are
either suppressed or directed to stderr.
Your own program then has stdout solely for its own use.

RE: Initiating secure connection to MySQL4 from PHP
Hello, This is discouraging after I spent most of the weekend getting OpenSSL working with our MySQL 4 server. Unfortunately I can't use Stunnel to secure the connection between our website and our MySQL server because our ISP will not allow me to run the Stunnel daemon on their servers. They have a web server farm and claim that they would need to configure Stunnel for me on each of their servers in the farm. How do people typically handle setting up Stunnel to secure their connections from a public ISP to their MySQL server? Is it possible that I only need to run the Stunnel daemon on my MySQL box? Securing the connection between a public ISP and a privately-hosted MySQL server seems like something that many people would have overcome by now. Am I really at the mercy of my ISP on this?

MySQL 4.0.9 is released
Hi, MySQL 4.0.9, a new version of the world's most popular Open Source Database, has been released. It is now available in source and binary form for a number of platforms from our download pages at http://www.mysql.com/downloads/ and mirror sites. Note that all mirrors may not be up to date; If you can't find this version on some mirror, please retry later or try another mirror. This is a new gamma release, fixing some recently discovered bugs. From the ChangeLog: --- Functionality added or changed: * `OPTIMIZE TABLE' will for MyISAM tables treat all `NULL' values as different when calculating cardinality. This helps in optimising joins between tables where one of the tables has a lot of `NULL' values in a indexed column: SELECT * from t1,t2 where t1.a=t2.key_with_a_lot_of_null; * Added join operator `FORCE INDEX (key_list)'. This acts likes `USE INDEX (key_list)' but with the addition that a table scan is assumed to be VERY expensive. One bad thing with this is that it makes `FORCE' a reserved word. * Reset internal row buffer in MyISAM after each query. This will reduce memory in the case you have a lot of big blobs in a table. Bugs fixed: * A security patch in 4.0.8 causes the mysqld server to die if the remote hostname can't be resolved. This is now fixed. * Fixed crash when replication big `LOAD DATA INFILE' statement that caused log rotation.

Re: Upgrading to version 4.

Re: Removing users
Ed, That would work but is there no way to completely remove their record? With REVOKE, you can partially or totally revoke privileges from users. What you can't do with REVOKE (in MySQL) is to erase a user completely. For this, you will have to DELETE FROM mysql.user WHERE User = 'user2bremoved'. You can even use this as an alternative way to remove users. You need two statements for this, just in case ... DELETE FROM mysql.user WHERE User = 'user2bremoved'; DELETE FROM mysql.db WHERE User = 'user2bremoved'; Opposed to GRANT and REVOKE DELETE will not cause the server to notice the privilege changes. You need another statement for this: FLUSH PRIVILEGES; This will force the server to reload the grant tables, and thus, the privileges.

Replication halts with sql syntax error
Description: There seems to be a problem with mysql replication. When the slave server encounters sql that uses backticks instead of single quotes. The +replication stops until you manually advance the position number in the master.info +file. How-To-Repeat: 1. Set up a replication server 2. enter in sql on the master server using backticks instead of singlequotes eg. DROP TABLE `ee_camera`, `ee_camera_type`, `ee_category`, `ee_counter`, `ee_country`, `ee_exhibition`, `ee_exhibition_feedback`, +`ee_lens`, `ee_light`, `ee_location`, `ee_message`, `ee_microthumb_path`, `ee_news`, +`ee_owner`, `ee_photo`, `ee_photo_size`, +`ee_photo_to_category`, `ee_photo_to_exhibition`, `ee_size`, `ee_thumb_path`, +`ee_thumbs`, `ee_workflow` 3. Watch the error log on the slave, it will stop replication at this point.

Re: Problem getting the last insert id in my application - connectiontimed out

(For brevity I have removes all 'error' checking etc, suffice it ot say the exception thrown is below). Now I CAN get it to work with last_insert_id() but I would rather not have to use another round trip to the DB. Here is my code.

preventing duplicate records when using WHERE foo IN syntax
Hello,
I need to get a single result from a SELECT from a table with the following sturcture:
component - varchar(25) primary key
catNum - varchar(25) primary key
price - decimal(10,2)
my component list may contain duplicate catNum ie:
primary drive -WD1GJB
- WD800JB
-none
secondary drive - WD800JB
-none
monitor -SONLCD19
-none
any one catNum will have the same price so when i go looking for parts, knowing the
catNum, i do this:
SELECT price FROM syscomp WHERE catNum = $catNum
no problem - i only look at the first return and am happy!
However when putting together a system - and i have the following:
$system = qq('WD800JB', 'SONLCD19', 'none', 'WD1GJB');
and insert that into my SQL as:
SELECT price FROM syscomp WHERE catNum IN ($system);
if 'WD800JB' is in TWO components, i get two results - thus, and incorrect number of
return results.
(price is doubled)
However when i use:
SELECT DISTINCTROW price FROM syscomp WHERE catNum IN ($system);
and my list looks like this:
$system = qq('WD800JB', 'WD800JB', 'SONLCD19', 'none');
i only get 4 results, the second 'WD800JB' is ignored.
The only solution i can think of is:
$system = ('partA', 'partB', 'partC', 'partD', 'partD');
foreach ($system){
SELECT price FROM syscompt WHERE catNum = '$_'
# incrememnt $total with the first resutl.
}
BUT this seems painfully slow - as this would result in up to 20 calls to the sql
server.
I could ensure that each $system had the matching component, to match on the primary
key, but i don't know how to set up the IN statement for a double part:
WHERE concat (component, '-', catNum) IN ($system)
can anyone help me with a solution.
thanks.

Re: Upgrading to version 4.

Instead of doing this, it is preferable to change the client to use the new 4.0 API. - My company's website is running version 3.23.53a, and the main client that uses MySQL is PHP 4.2.3. Will mysql_connect() no longer work in PHP? Although this manual entry is talking about the C API functions, I assume PHP uses these to communicated with MySQL. Perhaps I might be wrong, but I would like to just double check. The PHP MySQL API will still work for you. Additionally, there is a new API that is currently in development that is intended to support the new features of MySQL like SSL connections, prepared statements, etc. Cheers! -- Zak Greant [EMAIL PROTECTED] | MySQL Advocate | http://zak.fooassociates.com MySQL Tip: Find the highest score for a given name mysql SELECT name, max(score) FROM high_score GROUP BY name; Gosh, Batman.

Sounds like the same problem I'm having (for which I'm still stumped and don't know what has caused it): table mysql.user is read only.
