mysqld_multi doesn't support !include or !includedir directives
Hi, I try to use !includedir directive with mysqld_multi for load other option files but nothing is loaded by mysql. In the default my.cnf, I have only the includedir directive for my configuration directory : !includedir /etc/my.cnf.d And in /etc/my.cnf.d/mysql3306.cnf I have : [mysqld_multi] mysqld = /usr/bin/mysqld_safe mysqladmin = /usr/bin/mysqladmin user = toto password = toto log= /var/log/mysqld_multi.log [mysqld3306] port = 3306 socket = /var/lib/mysql_3306/mysql.sock pid-file = /var/lib/mysql_3306/test.pid datadir = /var/lib/mysql_3306 tmpdir = /tmp user = mysql mysqld = /usr/sbin/mysqld log-error= /var/lib/mysql_3306/test.err But mysqld_multi doesn't not load mysql3306.cnf file. # service mysqld_multi report Reporting MySQL servers No groups to be reported (check your GNRs) Whereas # my_print_defaults --defaults-file=/etc/my.cnf mysqld3306 --port=3306 --socket=/var/lib/mysql_3306/mysql.sock --pid-file=/var/lib/mysql_3306/test.pid --datadir=/var/lib/mysql_3306 --tmpdir=/tmp --user=mysql I found the Bug #29327 dated 2007 but without fix.

[ANN] ODB C++ ORM 2.4.0 released, adds MySQL stored procedure support
I am pleased to announce the release of ODB 2.4.0. ODB is an open source object-relational mapping (ORM) system for C++. It allows you to persist C++ objects to a relational database without having to deal with tables, columns, or SQL and without manually writing any of the mapping code. Major new features in this release: * Support for bulk operations in Oracle and SQL Server. Bulk operations can be used to persist, update, or erase a range of objects using a single database statement execution which often translates to a significantly better performance. * Ability to join and load one or more complete objects instead of, or in addition to, a subset of their data members with a single SELECT statement execution (object loading views). * Support for specifying object and table join types in views (LEFT, RIGHT, FULL, INNER, or CROSS). * Support for calling MySQL and SQL Server stored procedures. * Support for defining persistent objects as instantiations of C++ class templates. A more detailed discussion of these features can be found in the following blog post: http://www.codesynthesis.com/~boris/blog/2015/02/11/odb-2-4-0-released/ For the complete list of new features in this version see the official release announcement: http://codesynthesis.com/pipermail/odb-announcements/2015/41.html ODB is written in portable C++ (both C++98/03 and C++11 are supported) and you should be able to use it with any modern C++ compiler. In particular, we have tested this release on GNU/Linux (x86/x86-64/ARM), Windows (x86/x86-64), Mac OS X (x86/x86_64), and Solaris (x86/x86-64/SPARC) with GNU g++ 4.2.x-5.x, MS Visual C++ 2005, 2008, 2010, 2012, and 2013, Sun Studio 12u2, and Clang 3.x. The currently supported database systems are MySQL, SQLite, PostgreSQL, Oracle, and SQL Server. ODB also provides optional profiles for Boost and Qt, which allow you to seamlessly use value types, containers, and smart pointers from these libraries in your persistent classes.

[ANN] ODB C++ ORM 2.0.0 released, adds support for C++11, polymorphism
Hi, I am pleased to announce the release of ODB 2.0.0. ODB is an open source object-relational mapping (ORM) system for C++. It allows you to persist C++ objects to a relational database without having to deal with tables, columns, or SQL and without manually writing any of the mapping code. Major new features in this release: * Support for C++11 which adds integration with the new C++11 standard library components, including smart pointers and containers. Now you can use std::unique_ptr and std::shared_ptr as object pointers (their lazy versions are also provided). For containers, support was added for std::array, std::forward_list, and the unordered containers. * Support for polymorphism which allows you to persist, load, update, erase, and query objects of derived classes using their base class interfaces. Persistent class hierarchies are mapped to the relational database model using the table-per-difference mapping. * Support for composite object ids which are translated to composite primary keys in the relational database. * Support for the NULL semantics for composite values. This release has also been tested with GCC 4.7 and Clang 3.0 with the ODB compiler now supporting the GCC 4.7 series plugin interface. With this release we are also introducing a free proprietary license for small object models. A more detailed discussion of these features can be found in the following blog post: http://www.codesynthesis.com/~boris/blog/2012/05/02/odb-2-0-0-released/ For the complete list of new features in this version see the official release announcement: http://www.codesynthesis.com/pipermail/odb-announcements/2012/13.html ODB is written in portable C++ and you should be able to use it with any modern C++ compiler. In particular, we have tested this release on GNU/Linux (x86/x86-64), Windows (x86/x86-64), Mac OS X, and Solaris (x86/x86-64/SPARC) with GNU g++ 4.2.x-4.7.x, MS Visual C++ 2008 and 2010, Sun Studio 12, and Clang 3.0. The currently supported database systems are MySQL, SQLite, PostgreSQL, Oracle, and SQL Server. ODB also provides profiles for Boost and Qt, which allow you to seamlessly use value types, containers, and smart pointers from these libraries in your persistent classes. More information, documentation, source code, and pre-compiled binaries are available from: http://www.codesynthesis.com/products/odb/ Enjoy, Boris -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql

RE: Community Support better than Official Support? (was: Can I Develop using Community Edition and Deploy onto Enterprise Edition??)
That's a great attitude. I always appreciate it when a support organization listens to users. I've been on both sides of the fence, and I always hated it when there //was// a fence. One thing I always favored, again as both a user and as a tech support professional, was a public list of known bugs (excluding security-related ones, of course). It saves a lot of head-banging, the kind of frustration that can lead to a very high level of anger. Just last week I spent a day trying to get a particular feature to work (in a completely unrelated product), not knowing that it was flat out broken. The company in question has three options: - Paid support: they gave me a free trial, and I quickly discovered that it was useless. Their only response was Take two reboots and call me in the morning. - E-mail support: bitbuc...@blackhole.com - The user forum: it has many experienced users, some beta testers, and (because the product is used world-wide) a response time measured in hours. What it doesn't have is any presence from the company. As you can imagine, if not for the other users this program would be just a bad memory.

Two instances can replicate from one another yes, but precautions must be taken especially in the case of active-active configuration. Works perfectly indeed, to name the precautions to take: 1, Set proper server_id's 2. When using auto-incrementing fields, set the auto_increment_offset auto_increment_increment. 3. If you write on 2 servers simultaneously, UNIQUE indexes can break replication. If your application requires both enforcing them AND writing to both servers, look at clustering instead. -- Rik Wasmus -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql?unsub=arch...@jab.org

I read a few of the numerous tutorials on HOW TO USE THEIR HELP THING and I still don't understand it. I did a search for MySQL on their site and got NOTHING. Have they dropped all support for MySQL? Is there somewhere else we should go to pay for one on one support for things like my little join query problem? Has anyone else had a good experience with Oracle's MySQL support?

Re: CR: add support of interactive transactions for webclients
I can't speak for the MySQL people, but in my view your workaround is the correct way of implementing this. It is not the database's job to keep track of which user wants to keep what session open, and HTTP is stateless by design. Keeping transactions open for relatively long periods of time would be a major load on the database, as it needs to keep track of all the different changesets and consistent views. I'd rather have my database be good at handling data :-) I can see your need, but that's what middleware is for. -- Bier met grenadyn Is als mosterd by den wyn Sy die't drinkt, is eene kwezel Hy die't drinkt, is ras een ezel
CR: add support of interactive transactions for webclients
CR: add support of interactive transactions for webclients Hello, I dont know how to place an idea (CR) for mySQL. I try it that way. At the moment I am implementing an easy-to-use multiuser webclient for database usage. (phpMyAdmin in contrast is a very powerful tool for people with technical background knowledge and I like to use it.) In an multiuser environment the usage of transactions to avoid data loss by access conflicts between different users is mandatory. But: Webserver (e.g. apache) doesnt keep open the connection to mySQL after the script (e.g. PHP) has been executed. mySQL thread is terminated and any open transaction is rolled back. Idea (CR): provide new session-variable KEEP_PROCESS and new command CHANGE_PROCESS. --- scenario (simplified): user1 navigates through database SELECT but NOT for update user1 likes to checkout a row to do some changes: ?PHP mySQL authentification START TRANSACTION SELECT FOR UPDATE SET @@KEEP_PROCESS=1 // process shall NOT be terminated after connection has been closed SELECT CONNECTION_ID() data is displayed in webclient FORM for editing ? row (InnoDB) is locked for user1 and cannot be SELECT FOR UPDATE by any other user user1 likes to write the changes back: ?PHP mySQL authentification CHANGE_PROCESS $connectionId // process shall be overtaken if a lot of conditions are satisfied (see bellow) UPDATE . COMMIT SET @@KEEP_PROCESS=NULL // process shall be terminated after connection has been closed ? --- conditions for CHANGE_PROCESS $connectionId : - user (and host) have to match between currently active (new) process and (old, kept) process with ID=$connectionId - currently active (new) process and (old, kept) process have to have successfully finnished user authentification - (original, last) connection of (old, kept) process has to be terminated before active (new) process can overtake if (original, last) connection has not been terminated then CHANGE_PROCESS is queued until (original, last) connection terminates I have been implementing a workaround (around 500 lines of code) that implements the above described behaviour. But this is implemented in C++ as PHP to MySQL bridge acting towards PHP as simulated mySQL server on port 3307 and acting towards mySQL as simulated PHP client on port 3306. This workaround does satisfy my needs but of course it would be much better to have this functionality implemented directly in mySQL if other users need interactive transactions for webclients too. Please give me feedback. Thank you very much! Herbert Don't get soaked. Take a quick peek at the forecast with the Yahoo! Search weather shortcut. http://tools.search.yahoo.com/shortcuts/#loc_weather
Re: ENGINE=ARCHIVE doesn't support INDEX!!??
Correct. I assume the thinking behind it, is that you use that kind of table for huge amounts of inactive data, so it doesn't matter if your selects are a bit slower. Also, keep in mind that because it is a compressed file format, you will be scanning much more data per physical read than with a regular table, and so the table scan will be quite a bit faster, too. If there are specific values you tend to use in where clauses all the time, though, you can always consider partitioning the archived table.

Re: MySQL 5.4 Support for Mac OS X 10.6.x ?
Hi,
As I did not get any reply, I started to install the mysql-5.4.3-beta
osx10.5-x86_64 build on My Snow Leopard 10.6.2 64 bits , and I wanted to
share my user experience with you :)
the installation went well (logged as a normal user) though there were not
any mysql user created on my OS, all files installed at
/usr/local/mysql-5.4.3-beta-osx10.5-x86_64/
and a link /usr/local/mysql has been created pointing to
/usr/local/mysql-5.4.3-beta-osx10.5-x86_64/
I then tried to create environment variables following the here under docs
:
http://developer.apple.com/mac/library/qa/qa2001/qa1255.html
http://developer.apple.com/mac/library/qa/qa2001/qa1067.html
http://dev.mysql.com/doc/refman/5.4/en/setting-environment-variables.html

http://dev.mysql.com/doc/mysql-macosx-excerpt/5.4/en/mac-os-x-installation.html
but it did not work though I created a file
/Users/MyUserName/.MacOSX/environment.plist
?xml version=1.0 encoding=UTF-8?
!DOCTYPE plist PUBLIC -//Apple//DTD PLIST 1.0//EN
http://www.apple.com/DTDs/PropertyList-1.0.dtd;
plist version=1.0
dict
keyMYSQL_TCP_PORT/key
string3306/string
keyPATH/key
string${PATH}:/usr/local/mysql/bin/string
/dict
/plist
so I finally created a file e /Users/MyUserName/.bash_profile and this
worked for me :
MYSQL_TCP_PORT=3306
PATH=${PATH}:/usr/local/mysql/bin
export MYSQL_TCP_PORT
export PATH
I then ran
. .bash_profile
ls -al /usr/local/mysql/data/ and noticed the files are owned by a user
_mysql (group wheel) which I do not know (and does not exist I guess) :
I then successfully ran the here under command though I have not performed
yet the UNIX Post install
stepshttp://dev.mysql.com/doc/refman/5.4/en/mysql-install-db.html:
mysql -u root mysql
I finnaly downloaded the MySQL Workbench 5.2.10 beta
(mysql-workbench-oss-5.2.10-osx10.5-i686.dmg ) for Mac OS X 10.5 (x86,
32-bit) though I run mac Os X Snow Leopard 10.6.2 (x86, 64 bits) , I then
saw the wizard as described at
http://dev.mysql.com/doc/workbench/en/wb-installing-mac.html
and can succefully run the Workbench GUI.
I created then a new instance with a Mac OS X (MySQL Package) System
Profile and all looked fine except the configuration file path set by
default to /etc/my.cnf , which does not exist I only found a *.cnf
file at
/usr/local/mysql-5.4.3-beta-osx10.5-x86_64//mysql-test/suite/ndb/my.cnf
To be followed ... and congratulations to the MySQL Team for the quality of
this 5.4 beta version which looks yet great :)

Fwd: Does mysql support materialized views?
Query cache stores select query together with its results. When the same query is sent again, result from the cache is returned. Whenever some table is modified, all cache entries referencing it are deleted. That happens even when modification doesn't affect cached rows, eg.: SELECT a FROM a_table WHERE id = 1; # Result gets cached UPDATE a_table SET a = 2 WHERE id = 2; # Result is removed from the query cache SELECT a FROM a_table WHERE id = 1; # Query cache can't be used On Mon, Apr 20, 2009 at 12:56 PM, Lin Chun franks1...@gmail.com wrote: Hi I don't know very well MySQL, the query cache is something like the Snapshotone of the s mod listed in the query is modified, the in Oracle, so we can get the result immediately?

Additional language support for tracking server usage.
Folks, I work at a Web Hosting company and we were frustrated by our inability to account for user activity on a busy server. We could see gross spikes in activity by SHOW STATUS, but couldn't tell where they were coming from easily. We finally developed an extensive set of patches for MySQL and released them as Open Source (we hope it will get picked up in the main MySQL soon!). I have some brief examples below, you can read more and download the source at http://www.ExtSQL.com/ I'm also our representative on the INCITS (H2) technical committee (the US ANSI body with responsibility for the SQL standard) -- from our review of other major DB vendors these changes look like some welcome additions to the SQL standard (most likely under INFORMATION_SCHEMA).

Current state of CONNECT BY support in MySQL?
Many people seem to ask this question periodically but I wanted the most recent answer... What's the current state of having support for CONNECT BY in MySQL? I'm using MySQL 5.0.45 on CentOS 5.2 and noticed in the documentation that I can't write my own recursive functions: Stored functions cannot be recursive. http://dev.mysql.com/doc/refman/5.1/en/stored-routines-syntax.html ... so I guess I can't build my own recursive tree-traversing stored procedures. Is there support in MySQL 5.x, or MySQL 6.x for doing heirarchical queries? Does MySQL now ... or will it later ... support CONNECT BY syntax? Help would be appreciated. -- Dante -- D.

I am not seeing this mentioned in Mysql, but I might be overlooking something. So does it support groups? No, just straightforward user accounts with individual GRANT and REVOKE. I too miss groups/roles, alas. If it helps, the way I tend to manage it is just assign everyone to the same user account, and name it as though it's a group -- e.g. analyst, developer, intern, and so forth. I know that's not the same thing and has obvious limitations, but for my purposes it's easier than having to maintain many accounts.

Re: Table compression with write (append) support

Currently all access log files are stored as files and compressed by day. Older log files are compressed by month, with bzip2. This gives a very good compression ratio, since there's a lot of repetition in those files. If I store all that in a regular table, it would be several gigabytes large. So I'm looking for a way to compress the database table but still be able to append new rows. As the nature of a log file, it is not required to alter previous data. It could only be useful to delete older rows. Do you know something for that? You want the ARCHIVE storage engine. http://dev.mysql.com/doc/refman/5.0/en/archive-storage-engine.html Huh. This is the first I've heard of the archive engine. Cool! However, I'm curious how the compression offered by OPTIMIZE TABLE and the zlib library would compare to denormalization of the log schema. In particular, I imagine a lot of the HTTP requests would be the same, so you could create a table to store the requested URLs, and then have a second table with the timestamp and foreign key relationship into the first. Depending on how wide the original rows are and how often they're requested, I imagine you could get quite a savings. Anything else that's repeated as well? IP's? Return codes? Would be curious about the results if you were able to implement both.

Then you could use the MERGE storage engine to provide a view over all the tables as though they are one.

My guess is not /that/ much work, since you should only have a known and relatively small set in this dictionary, it'd basically be cached the whole time. But, that's my guess. Haven't tried it. Practice and theory . . . Also, URLs sometimes contain things like session IDs. They're probably not of interest for my use but it's not always easy to detect them for removal. Really? Why wouldn't it be easy to detect them? You presumably know what variable you're looking for in the URL string, and applying a simple regex search-and-replace . . . ? IP addresses (IPv4) and especially return codes (which can be mapped to a 1-byte value) are probably not worth the reference. Data size values should be too distributed for this. Well, presumably, you'd normalize that part of the table. That is, rather than include multiple foreign keys in your data rows, you'd create a cartesian product of the the return codes with the dictionary table. You'd have a slightly more bloated dictionary, but depending on the number of requests the site(s) get(s), the aggregation would more than make up for it. I could also parse user agent strings for easier evaluation, but this takes me the possibility to add support for newer browsers at a later time. (Well, I could update the database from the original access log files when I've updated the UA parser.) Same thought. If you've only a known set of UA strings, you could normalize them with the dictionary table as well. How large is a row reference? 4 bytes? I don't know, I'm fairly new to MySQL. I suppose it'd also matter on the type of index. Anyone more knowledgeable wanna pipe up? Well. Whatever method works for your needs, cool. I'm going to check out both MYISAMPACK and ARCHIVE.

If you've only a known set of UA strings, you could normalize them with the dictionary table as well.

Table compression with write (append) support
Hi, I'm thinking about using a MySQL table to store an Apache access log and do statistics on it. Currently all access log files are stored as files and compressed by day. Older log files are compressed by month, with bzip2. This gives a very good compression ratio, since there's a lot of repetition in those files. If I store all that in a regular table, it would be several gigabytes large. So I'm looking for a way to compress the database table but still be able to append new rows. As the nature of a log file, it is not required to alter previous data. It could only be useful to delete older rows. Do you know something for that? -- Yves Goergen LonelyPixel [EMAIL PROTECTED] Visit my web laboratory at http://beta.unclassified.de -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

FK support on myISAM, Parallelization, pronunciation and all kinds of goodness...
Whoa!? I was just reading this page (http://en.wikipedia.org/wiki/MySQL), and noticed a few things... http://en.wikipedia.org/wiki/Foreign_key Foreign key support for all storage engines will likely be released with MySQL 5.2 (although it has been present since version 3.23.44 for http://en.wikipedia.org/wiki/InnoDB InnoDB). Does this mean that myISAM tables will have FK support? So I can then ditch this InnoDB with all the transaction bloat, and the fact that auto_increment PK resets itself. http://dev.mysql.com/doc/refman/5.0/en/innodb-auto-increment-column.html And the second interesting thing is: Support for http://en.wikipedia.org/wiki/Parallel_computing parallelization is also part of the roadmap for future versions Does this mean we can have several mySQL servers all running as one, on different physical servers. Sort of like clustering, or maybe RAID-ish? What are the current roadmap dates(ish) for these features. And I'm sure this has been asked a billion times, but when will 5.1 branch become GA (again, ballpark)? ÐÆ5ÏÐ PS. Here's a bit of trivia for you if you don't feel like reading the whole wikipedia page: MySQL's official pronunciation of the name is My Ess Que Ell, pronounced as /maɪ ɛs kjuː ɛl/, not My sequel /maɪ siːkwəl/. However, the company does not take issue with the pronunciation My sequel or other local variations. The My portion of the name comes from the name of Widenius's child, spelled My but pronounced in http://en.wikipedia.org/wiki/Swedish Swedish as mü /my/ (or approximately in English, me). The SQL portion uses the fully spelled-out pronunciation of the http://en.wikipedia.org/wiki/Acronym_and_initialism initials, S-Q-L (Structured Query Language), not the sequel pronunciation. This adheres to the official ANSI pronunciation but conflicts with the earlier IBM database of that name.[5] http://en.wikipedia.org/wiki/MySQL#_note-3 The Swedish (MySQL AB is a Swedish company) word Myskväll (/myskvæl/ cozy evening, or My's evening as Mys kväll) is pronounced in a similar way, but this may be a coincidence. Nevertheless this pronunciation is quite usual in Sweden. The dolphin symbol in the MySQL http://en.wikipedia.org/wiki/Logo logo was given the http://en.wikipedia.org/wiki/Swati_language Swati name Sakila in October 2002 after a naming contest
Re: Question on InnoDB support
Hi Waldo, all! [EMAIL PROTECTED] wrote: I'm making an assessment of MySQL possible official adoption in my company. A question I have is: with InnoDB codebase being owned by Oracle, is there any impact to its reliability and support? Any other issues? The developers of InnoDB have never been employees of MySQL AB but rather worked for an independent company, Innobase Oy (AFAIR). There were contracts between Innobase and MySQL about cooperation and support, and this worked well to the satisfaction of all parties (including the customers). Last year, *after* Innobase was bought by Oracle, these contracts were renewed (the old period had expired), and cooperation and support continue as before. InnoDB developers continue to be active on this mailing list and in MySQL bug handling, so I see no reason to be concerned.

MySQL IPv6 Support?
Hello, I have searched every corner of the internet for info on MySQL's IPv6 support, but have not found much information. I have a Linux box with an IPv6 address. It can be pinged from other machines (Linux and Windows) by its IPv6 address. However, I cannot get this command to work: mysql -h ::1 This gives me an “Unknown Host” error. Has anyone ever gotten an example like that to work? This is the IPv6 equivalent of mysql -f 127.0.0.1 (which works on that machine). Obviously, my goal is to do something a bit more complicated, but I can't even get that simple use of IPv6 to work. Any help appreciated. -- View this message in context: http://www.nabble.com/MySQL-IPv6-Support--tf3584588.html#a10016526 Sent from the MySQL - General mailing list archive at Nabble.com. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
