DO is like SELECT, except that it doesn't return any results. Also, is there a equivalence to the MSSQL statement; SET NOCOUNT ON ...in MySQL, which suppresses the rows affected messages? Not AFAIK. You can make the MySQL client less verbose (which includes suppressing the rows affected message) by starting the client with the --silent/-s option.

Clarifying the MySQL Licensing Policy Documents Pt. II
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Greetings All, Sorry for the long delay in following up! First, I have resigned from my position as MySQL AB Community Advocate for personal reasons. If you have concerns regarding licensing and community issues that you wish to directly engage MySQL in, you should write to either [EMAIL PROTECTED] or [EMAIL PROTECTED] Also, rather than create a separate request tracker for the licensing issues, our webmaster has (smartly) added a category in the standard MySQL bug tracker (http://bugs.mysql.com/). So, let us recap where we left off in these discussions with a slightly modified version of the notes from my prior message on this issue: As a way to cooperatively work to address some of the licensing concerns held by members of the MySQL community and the broader Free Software/Open Source community, we are initiating a community review of our licensing policy documents. This means that we are soliciting feedback about issues in the policy documents that people find inaccurate or unclear. From this feedback we will work to improve the policy documents. Please note that we cannot guarantee that we will address or accept all of the issues raised or suggestions made. The licensing is both complex and is the cornerstone of our business. Past experience shows that we must work carefully, incrementally and with community involvement in this area. As with development of the FLOSS exception though, I hope that we can reach a compromise that is satisfactory for almost everyone. If you wish to participate, the process for doing so is simple. Review some or all of the following documents: * http://www.mysql.com/products/licensing/ * http://www.mysql.com/products/licensing/commercial-license.html * http://www.mysql.com/products/licensing/opensource-license.html * http://www.mysql.com/products/licensing/faq.html When you encounter an issue that you find confusing or inaccurate, please file a bug report in the MySQL bug tracking system at http://bugs.mysql.com/. Please check to see if the bug has already been reported - if so, consider commenting on the existing bug. If creating a new bug, please make sure to set the category of the bug to Licensing. Additionally, it would be optimal if you could send a note to the MySQL community list on the issue - forwarding the message provided by the bug tracking system should be an easy way to do this. I would like the discussion to take place on the MySQL community list, as it is easier to keep track of the issues in a single, low-traffic setting. I prefer not to Cc the MySQL General list beyond this initial email, so as to avoid cluttering an already busy mailing list. As for the policy documents, MySQL CEO Mårten Mickos made a small set of alterations to the docs that he noted at http://slashdot.org/comments.pl?sid=118195cid=9987564 Thanks to everyone for their input and effort here!

Does the second part 2) applies to the developer of proprietary software only or does it apply to its users too ? Hi! The second part only applies to the distributed copies of MySQL. Each distributed copy of MySQL needs to have a valid license. This can be the GPL, or if the distributor cannot comply with the GPL, then they should have one proprietary license for every copy of the software that they ship. To make our money on licensing and to keep things simple, we always recommend that proprietary use of MySQL be done under a proprietary license. This is not required in all cases though. Why a user cannot install and use MySql under GPL and then install and use proprietary software under whatever licence he got it. A user can do this. However, if a developer of proprietary software that is based on MySQL distributes that software, then they need to make sure that the distributed copies have valid non-GPL licenses. Or do you want to say that the end user can in general use MySQL under GPL, but as soon as he tries to use it with that particular proprietary software then he can no longer use MySQL under GPL ? This seems to contradict the GPL license terms Users are free to use MySQL under the terms of the GPL as long as they comply with the terms of the license. They can even use GPL licensed MySQL and proprietarily licensed versions of MySQL at the same time.

Ok, but if I say to a client (that has his own web server) you will need to install Mysql on your server to run the site I'm writing for you, will he need a license? Hi Leonardo, We always recommend that proprietary use of MySQL be done under our for-pay license. This is a simple recommendation that helps us fund development and is always correct. However, if you are creating a work for a client who has hired you to build something for them, then chances are quite good that MySQL can legally be used under the GPL. If you build a proprietary software product that is based on MySQL and distribute this to customers, then you probably can't do so with the GPL licensed version of MySQL and would need to purchase non-GPL licenses for MySQL.

In every other case you need a commercial license. The point of GPL are: - full source of all the code - every work derived from the original must be distributed under gpl - right to modify and distribute all the software (with gpl). So you can not distribute any software that requires MySql (or other gpl source code) without a GPL license. Now a question: Where is the text of commercial license; I have one trouble: Can I buy a license (1 for each server) and sell my application to a reseller that will sell my application, hardware and technical support to the real customer? Hi Santino, Good question! I don't usually deal with the details of the proprietary MySQL licensing, but I would guess that as long as a MySQL server has a valid license, we don't care how it gets to then end user. I can put you in touch with one of our sales team members to get you more information.

Re: using mysql in commercial software
Greetings All, LinuxWorld is now finished (meaning that some of the key MySQL people who need to be in on these discussions will be back to a more normal working setup) and the weekend is more or less here. I hope to pick up discussions on these issues with the other MySQLers on Monday (or to word it differently, I hope to avoid talking about licensing on my weekend! ;) Also, this discussion is a better fit for the community list ([EMAIL PROTECTED]). There are already a group of people interested in the licensing issues on that list. Unless people feel strongly, I will move this issue to that list. I urge those with an interest in our licensing and other community issues to subscribe to the community list. Those who are subscribed to our community list but not the MySQL general list, see http://lists.mysql.com/mysql/169680 to catch up on the discussion thread this message refers to.

Re: using mysql in commercial software
Hi Mike, On Aug 06, 2004, at 18:08, mos wrote: This means that, according to the most common interpretation of the GPL, just linking with them automatically requires your code be under the GPL. License: The GPL license is contagious in the sense that when a program is linked to a GPL program, all the source code for all the parts of the resulting product must also be released under the GPL. One important note here: The GPL does not behave in the way described above. There is no requirement to distribute software that you build with or on top of GPL-licensed software to others. However, if you choose to distribute software that is a derivative work (defined in US copyright law as A ''derivative work'' is a work based upon one or more preexisting works) of GPL-licensed software, then the software can only be distributed under the GPL. So what if the client app doesn't require the MySql client libraries in order to access the MySQL database? My client application requires no dll's at all, because everything is compiled inside an .exe file. That's because I'm using a 3rd party set of components that bypasses the libmysql*.dll libraries altogether. My application doesn't link to MySQL's code, GPL or otherwise. Does this now make my application license free even if I distribute it for $$$? Or will the software police come banging on my door at 4 AM looking for me? This architecture might bypass the requirements of the GPL - I don't really know. The best course of action here is to consult a lawyer who is an expert in Free Software/Open Source software licensing who can advise you of the validity of your course of action for your given situation. We would probably assert that the software forms a derivative work with GPL-licensed MySQL because the software would likely not function without MySQL. However, this is a tough area to speculate on. As we are not lawyers (nor are we in the business of giving free legal advice to help people circumvent our own business model :), we always recommend that proprietary applications (aka applications that do not share their source code and the rights to modify it with others) should always use the proprietarily licensed version of MySQL. This recommendation ensures that our licensing terms are never violated and helps us generate revenue to fund development of the database. Usually, people who distribute proprietary applications are selling them. We feel that it is reasonable to charge users who wish to charge their users and who do not give their users the freedom to view, modify and share the source of the application. We also suggest that people consider putting their software under a Free Software/Open Source license (such as the GPL, the BSD license, the Apache license and so on). Then they can use MySQL for free. This model may not work for everyone, but there is still significant potential for revenue with the model by selling the application at a fee that the market finds reasonable, along with related services like hosting, support, consulting, etc. People may also want to consider using a dual-licensing model that allows them to share with others who choose to use Open Source/Free Software licenses, but gives them a revenue stream from people who prefer traditional proprietary licenses.

Re: using mysql in commercial software
Greetings All, I walked through the mailing list thread earlier today. The big issues that I believe that people raised were: * Incorrect information on distribution as it applies to the GPL in our licensing documents * Lack of clarity from MySQL on what is and not acceptable use of GPL-licensed MySQL * Lack of concrete examples of suitable/unsuitable use of GPL-licensed MySQL I opened up a new ticket at http://zak.greant.com:/licensing/tktview?tn=40 to cover the last two of issues. The ticket is rather terse, but I think that we all understand the issues. The existing ticket http://zak.greant.com:/licensing/tktview?tn=32 seems to cover the first issue. Also, I have started discussing these issues with the other MySQLers and hope to have something useful to report soon. I understand that this is not optimal because it does not involve all of the people who have a stake in the licensing. Frankly licensing is a tough issue for us - it is the base of our revenue and it affects many people within and without the company. Additionally, it is a legal issue - something that makes many people, including us, very cautious. Please continue to provide feedback on this area using any channel that you feel comfortable using. I admit that I prefer knowing about feedback on MySQL, so a courtesy Cc to me at [EMAIL PROTECTED] and/or to our community list ([EMAIL PROTECTED]) and/or an open ticket in the licensing issue tracking system (http://licensing.zak.greant.com) are all greatly appreciated.

Community Contributor Discount for the 2004 MySQL User Conference
Greetings All, As promised a few weeks ago (but only delivered today), MySQL is offering a $100 discount on the MySQL 2004 User Conference conference fee for attendees who contribute to the Free and Open Source Software commons. The purpose of this discount is both to reward people for their work in the community and to encourage others to start contributing. To get the discount, you need to have made a significant contribution to the Free and Open Source Software (FOSS) community. Demonstrating this should be fairly simple. Some examples of how your might do this could be: - mail me links to some support entries from FOSS support lists that you contribute to - show me a software package that you have contributed to that is released under a FOSS license - show me links to CVS commit messages for FOSS-licensed software documentation - etc You don't need to be an expert or a project leader to get the discount. Just show a consistent activity and a strong commitment to helping other people in the community! If everything looks good, I will email you a code and instructions so that you can register online. If I have some questions, I will write. I know that this is not a very objective system, but it will have to do for this year's conference! :) Also, if you have already paid the conference fee, we can retroactively apply the discount if you follow the above steps. Please Note: If you have already received the early bird discount, I can't give you this discount. Still, drop me a line and I will buy you a beverage of your preference at the conference. :) Cheers! -- Zak Greant MySQL AB Community Advocate -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
MySQL User Conference Computer Lab Sessions and Early Bird Sessions
Greetings All, If you are interested in attending the conference in person (or virtually), please read on. First, in addition to our regularly scheduled conference sessions, we are going to be having about a dozen training sessions. The sessions will let small groups of attendees (about 10 per session) get 30 to 90 minutes of hands-on training with MySQL staff and MySQL community leaders. We will be covering topics like query and server optimization, coaching on new (and old) feature use and providing step-by-step demos of some cool new software. Perhaps the most exciting session for the veteran hackers on this list will be a 90 minute workshop with some of our developers (including Monty) where they will walk you through the major architectural components (and the corresponding source) of the MySQL database and MyISAM storage engine. While MySQL is providing the speakers for the sessions, Apple is graciously providing the computers - students will be sharing a shiny new G5 during the training. We are currently looking at ways to let people participate virtually in some of these sessions and are going to be testing the use of VNC and other remote technologies. If you want to participate in the testing, please write me personally and let me know. These sessions will be included in the conference fees, but space is limited and attendees will have to register to participate. A fixed list of sessions and registration for them should be posted next week. The conference team will send out an informational message at that time. Speaking of conference fees, the $100 early bird discount ends on February 14th. To take advantage of the discount, visit https://order.mysql.com/?sub=pgpg_no=14 Also, as a reward for the people who help keep Free Software and Open Source going, I am happy to announce that we will be offering a discount to the conference fee to those who actively contribute to the software and community commons. I will post the guidelines for eligibility early next week. If you have any questions, feel free to drop me a line - though please note that I will be traveling for the next week and may take a day or three to respond. Finally, if the mention of the conference comes as a surprise to you, visit http://www.mysql.com/events/uc2004/ for an overview.

MySQL User Conference 2004: Choosing the Internals/Advanced Sessions
Greetings All, My name is Zak Greant. I work for MySQL AB as their community advocate - I am also helping to organize the content for our upcoming MySQL User Conference (http://mysql.com/events/uc2004) that is happening in April. Our deadline for choosing the final list of sessions is a couple of days away. We have so much excellent content that has been proposed that we need some help from the community in choosing the content that is best for the event. Here are seven advanced/internals talks that we are considering. Please let me know which talks you would best like to see. Notes: * We will be posting addition information on the accepted sessions to http://mysql.com/events/uc2004/sessions.html within the next day. * Even if you are not going, your feedback is valuable to you as we will work to post papers from most of the accepted sessions. * We are open to suggestions for other content in the form of BoF sessions and lightning talks (see http://www.mysql.com/events/uc2004/speakers.html) The session titles are: * Connecting Data to MySQL, writing a simple Storage Engine * Hack Proofing MySQL * MySQL performance comparison on RedHat linux, Debian GNU/Linux and FreeBSD * Performance tuning for Innodb storage engine * Protecting Private Information with MySQL * Speed, Flexibility, Security: The MySQL solution to a large-store XML dilemma * The Badger Project: Improving MySQL Performance on Modern Computer Architectures Connecting Data to MySQL, writing a simple Storage Engine Noted community hacker Brian Aker demonstrates how to write your own custom storage engines for managing specialized types of data. Hack Proofing MySQL MySQL databases are a common point of attack because they typically hold the most valuable information for an organization. Because of this, locking down your MySQL databases is critical. This presentation will cover how a hacker approaches your database, the most common attacks, the most successful attacks, and how to prevent yourself from ending up as a victim. Secure your MySQL server involves properly configuring the database, educating your developers, and developing your applications to access the database securely. We will cover attacks such as SQL Injection, password brute-forcing, buffer overflow, and privilege escalation. Attendees will learn: 1) How attackers attack a MySQL server. 2) How to securely install and configure MySQL. 3) How to securely write applications for MySQL. MySQL performance comparison on RedHat linux, Debian GNU/Linux and FreeBSD When talking about databases, we normally do not think about the underlying environment on which the application is running, but this can represent a great advantage or drawback if we consider that each programmer, the application developer and the operating system developer, have to focus on his own work and depends on the work of the other.The two components have to be fine tuned to smoothly work together. When WillyStudios.com had to decide which one was the best platform to deploy its work on, we tested each environment thoroughly. In this talk we are going to present the results showed by our survey and discuss which ones are the best methods to have higher performances from the same database environment on different platforms. InnoDB Performance Tuning This session will demonstrate techniques for optimizing the performance of the InnoDB storage engine. The speaker will cover both MySQL server configuration as well as best practices for application development and OS tuning/hardware tuning. The advice provided will be supported by benchmark results. Protecting Private Information with MySQL Website managers must balance the need to provide customization with the responsibility to protect the private and sensitive information of customers. This talk will explore how some of the built-in encryption features in MySQL can create safe, strong and secure systems to guard against hackers and malicious insiders. It will begin with some simple examples and culminate with an extended example describing a website that offers all of the features of a highly-customized website like Amazon.com without keeping any personal information around. It will be the equivalent of having your cake and eating it too. Speed, Flexibility, Security: The MySQL solution to a large-store XML dilemma While MySQL databases have been used for years by the LANL Digital Library Development Team, it has been in the creation of our most ambitious project that we have truly recognized some of the unique strengths and features of MySQL. The project -- development of a comprehensive database of scientific journal articles and citation information -- involves converting bibliographic metadata from 8 distinct data suppliers into a common XML format, enhancing the data with links between each of the 50 million articles and their 507 million individual
MySQL User Conference 2004: Choosing the General Sessions
Greetings All, My name is Zak Greant. I work for MySQL AB as their community advocate - I am also helping to organize the content for our upcoming MySQL User Conference (http://mysql.com/events/uc2004) that is happening in April. Our deadline for choosing the final list of sessions is a couple of days away. We have so much excellent content that has been proposed that we need some help from the community in choosing the content that is best for the event. Here are five general talks that we are still pondering. Please let me know which talks you would best like to see. Notes: * We will be posting addition information on the accepted sessions to http://mysql.com/events/uc2004/sessions.html within the next day. * Even if you are not going, your feedback is valuable to you as we will work to post papers from most of the accepted sessions. * We are also examining ways to let people who cannot attend still experience a few of the hands-on technical sessions via technology like VNC, live audio streams and/or IRC * We are open to suggestions for other content in the form of BoF sessions and lightning talks (see http://www.mysql.com/events/uc2004/speakers.html) The session titles are: * Best Practices for MySQL Administration in an Enterprise Environment * Large Volume Data Transformation and Warehousing using MySQL * MySQL as an Embedded Database: An Implementation Story * Web Development with Bells and Whistles using MySQL * Show Me the Money: Getting Your MySQL Certification Best Practices for MySQL Administration in an Enterprise Environment Best practices to effectively manage MySQL servers in the non-web space. Best practices are bunches of norms that generally make systems safer and cheaper. We will briefly review system configuration guidelines and what best practices means. The core presentation will review practices for space and perforamnce management, object management and UDFs, security, replication, backup, recovery and disaster recovery. The talk should be useful for both new and veteran MySQL DBAs, and will focus on MySQL 4.1. Large Volume Data Transformation and Warehousing using MySQL In this session we describe a set of transformations and their corresponding layers for loading data into a data warehouse. Standard SQL is used in all steps and queries are performed on whole sets of data. The features include historisation of data, placeholders for orphaned records, type checking, consistency control, duplicate count, model transformation and optimizations. After extracting data from an operational system you are often left with relational, but not necessarily consistent data stored as text files with some kind of structure. However, for the purpose of doing analysis we need high data quality and performance, which is achieved through an efficient and consistent data model. The tables within it are our goal. In between the data is transformed and refined in several stages. In the process the data passes through different layers of transformation, where each layer is represented with its own namespace using MySQL databases. To begin with there is a temporary layer containing tables that have a one to one correspondence with the files. These are character based to ensure that no data is lost when reading the files into the database. Internal consistency and duplicate analysis is done here according to an XML definition of the model. The next layer is the raw layer, which is similar in model to the temporary layer with the exception of being persistent and having types. For data that should be historised only those records in the temporary layer that are new or constitute changes to data in raw are moved. Type, model and range errors are flagged here and another duplicate check is performed with respect to all data. Within raw we should have a complete history of all data contained in the files with some extra metadata. The model is the same as the one implied by the data in the files. Having come this far could sometimes be enough, but since this model could be denormalized we take the process one step further and provide a mechanism for converting the data into a new model. This is also useful for substituting compound natural keys with simple surrogate ones and thereby increases performance. In order to do so a key lookup layer is introduced, containing the natural keys from the raw layer together with auto incremented surrogate keys. This layer is further used to produce surrogate keys from foreign keys in orphaned records, which ensures consistency. The model in the key layer is the same as in our warehouse layer, which is loaded using a combination of data in the raw layer with the surrogate keys. The warehouse is in our case normalized according to 3NF, yielding efficient storage since data is not duplicated in the tables. However, when doing analysis we could utilize far better models when it comes

Re: Licence question
Good Day All, Let me attempt to provide some clarity on this issues (though it is important to note that I am not a lawyer or a judge.) The fundaments of the GPL are easy to understand. The GPL operates within standard copyright law. Under copyright law[0], the copyright holder has a bundle of rights related to their work. These rights including the right to control the copying, modification and distribution of their work. The holder can keep these right or they can grant others some or all of the rights as well. If they grant others rights to their work, they usually do so under the terms of a license. The GPL is one such license. It gives you the right to copy, modify and distribute the work as long as you follow some conditions. The important conditions for this discussion are: * You must distribute (or at least make available) the source code for the software. * If you form a derivative work with GPL licensed software, then the resulting work should also be GPL licensed. [1] Derivative work is a term from US copyright law (though most copyright laws have some similar concept). A derivative work is a work that is based in whole or in part on another work. There are no fixed rules on determining when a derivative work is formed. In some cases, it is very clear. If I were to modify GCC by changing a few constant names, it would certainly be a derivative work. If I had a program that used a database abstraction layer to allow it to communicate with a broad class of databases, maybe I would not be forming a derivative work with any of the databases. If I used an abstraction layer to specifically avoid creating a derivative work, but my product was intended to only work with one database, then it would be a different situation again. The technical process used (linking methods, abstraction layers, communication layers, ...) cannot be the only determining factor of whether a derivative work is or is not formed. If it were, then it would allow software licenses (both free and non-free) to be easily circumvented. Instead the end intent of the action must be taken into account. A good analogy for this is the case of someone dying due to someone else's actions. Consider the following cases: I drop a heavy potted plant on David. (He has a great comics collection that I covet. ;) I ask Mark to drop a heavy potted plant out the window, but I don't tell him that David will likely be killed by this. Mark falls out of the window because the plant is really heavy. David shoots Marks because he thinks that he is going to drop a potted plant on him. Which of the above is murder? Who is responsible? It really depends on how much is known about each situation. If David shoots Mark, and Mark is the only person who knew that I asked him to drop the plant out the window, then I would seem to be innocent (unless I was recorded urging Mark to drop the pot or I confessed). The context that an event occurs in has a tremendous effect on how it is perceived. My view on this issue are quite simple: If you are willing to pass on the rights that we grant you under the GPL, then please use MySQL under the GPL. If you do not want to pass on these rights then you should purchase a commercial license. In many ways, MySQL behaves like a typical Free Software/Open Source developer. We write software that we place under an open license. We also sell services and software so that we can make money. It just so happens that the same software that we put under an open license is the same software that we sell. [0] Note that different countries have different copyright laws. The exact bundle of rights and how they are protected vary from country to country. [1] A relevant section of the GPL is section 2b: 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: ... b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License.

We are looking for sessions that speak to your peers: practical, pragmatic and clueful presentations that focus on how you solved problems in a demanding or unique technical environment. Session that introduce a particular feature set or provide hands-on training to introduce newer developers to cutting edge functionality are also welcome (as is any cool or unique presentation). You can give sessions that range in length from 5 minute lighting talks up to 90 minute power tutorials. We also have set aside slots for 30 minute technical briefs and standard hour long sessions. Additionally we are looking for solid ideas from the community for Bird-of-a-Feather (BoF) sessions. These sessions give conference attendees a chance to meet and discuss topics of common interest with their peers. Visit http://mysql.com/events/uc2004/speakers.html to suggest ideas for the BoFs that you would like to participate in. The call for papers closes on January 14th. The conference will take place on April 14th to 16th in Orlando, Florida, USA. The call for BoFs and lightning talks closes on February 14th. For additional inspiration, check out last year's schedule: http://mysql.com/events/uc2003/schedule.html If you want to briefly discuss your ideas, fill out the appropriate form at http://mysql.com/events/uc2004/speakers.html and make a note in your comment.

Re: MySQL 4.1 and PHP/Perl Clients
On June 25, 2003 09:59, PAUL MENARD wrote: ... I've been considering upgrading my data , MySQL 3.23.42 to 4.013 or even going to 4.1. I've read on the MySQL upgrade documents that some client might be affected when upgrading to 4.1. It does specifically mention Perl which I use to supplement PHP. By I'm more concerned about PHP. Should I be concerned? Yes, it will not work at all. MySQL 4.1 uses a protocol that's not compatible with MySQL 3.23 and 4.0. Hi Paul, MySQL 4.1 does use a new enhanced protocol that supports cool things like compression and prepared queries. However, a 3.23.x/4.0 client can still connect to a MySQL 4.x version server. If you are upgrading from a non-4.1 version and do not update the mysql user table to the new format, then connecting will be no problem (However, the password hashes used in 4.1 are much harder to compromise.) If you are setting up a new 4.1 server, you can set --old-passwords when starting mysqld to force the server to use old passwords, or use the OLD_PASSWORD() function to set a users password to the old-style password, which would allow a 3.23/4.0 client to connect. Look for some extra info at http://www.mysql.com/doc/en/What-to-do-from-4.0.html You need to use the ext/mysqli extension for it to work, but there are two problems with this: 1) it is only available with PHP5 which is not released yet. PHP 5 will be released in a beta stage shortly. IIRC the mysqli extension has been or will be ported to PHP 4. 2) it cannot be legally used since the MySQL 4.1 client libraries have been re-licensed under the GPL (old versions of the client libraries used to be under the more friendly LGPL). We are currently working on an extension to allow MySQL to be linked and distributed with software that is licenced under a valid open source license (as defined by the Open Source Initiative - http://www.opensource.org/) This will allow PHP to use us without licensing issues. As for Perl, IIRC the DBI stuff is dual-licensed under Artistic/GPL - like the rest of Perl. DBI should have no problem with the licensing change. The details are still in flux - expect firm details in a few weeks or so.

Hi
When creating a table can you use multiple Table_Options?
Heh. Why not just try it? :)
The O'Reilly Managing Using MySQL show on page 288 a table been created
with two options ...)AUTO_INCREMENT = 1, TYPE=InnoDB;
No comma is needed.
But the MySQL manual says or:-
table_options:
TYPE = {BDB | HEAP | ISAM | InnoDB | MERGE | MRG_MYISAM | MYISAM }
orAUTO_INCREMENT = #
.
Hrm. It does not look like we explicitly state that you can use
multiple options anywhere on the CREATE TABLE page in the manual.
I will ask our documentation team to fix it.
Thanks!

There is an exception: if you set AUTO_INCREMENT in a secondary column in a multi-value primary key, then deleting the highest value in the secondary column will allow that value to be reused in the auto-increment sequence. i.e. CREATE TABLE user_log ( id SMALLINT UNSIGNED NOT NULL, event MEDIUMINT UNSIGNED NOT NULL AUTO_INCREMENT, PRIMARY KEY (user_name, event) ); mysql INSERT user_log (id) VALUES (1),(1),(1); Query OK, 3 rows affected (0.00 sec) mysql SELECT * FROM user_log; ++---+ | id | event | ++---+ | 1 | 1 | | 1 | 2 | | 1 | 3 | ++---+ 3 rows in set (0.00 sec) mysql DELETE FROM user_log WHERE id=1 AND event=3; Query OK, 1 row affected (0.01 sec) mysql SELECT * FROM user_log; ++---+ | id | event | ++---+ | 1 | 1 | | 1 | 2 | ++---+ 2 rows in set (0.00 sec) mysql INSERT user_log (id) VALUES (1); Query OK, 1 row affected (0.00 sec) mysql SELECT * FROM user_log; ++---+ | id | event | ++---+ | 1 | 1 | | 1 | 2 | | 1 | 3 | ++---+ 3 rows in set (0.00 sec) Cheers! -- Zak Greant [EMAIL PROTECTED] | MySQL Advocate | http://zak.fooassociates.com Using and Managing MySQL MySQL Training: Hamburg, March 24-28, 2003 Visit http://mysql.com/training for more information While we are postponing, life speeds by.--Lucius Annaeus Seneca - 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?

You can create the backup with the mysqldump utility, with replication or by copying the data files. See http://mysql.com/doc/en/Backup.html for more details.

Off-Topic Posts
Dear Readers, Over the last week there have been a series of messages posted to this list that were off-topic, inflammatory and often offensive. Our list manager contacted the offending parties and requested that they stop their abuse of the mailing list. When this failed to stop the postings, the administrator unsubscribed the offending user from all MySQL mailing lists and revoked their posting privileges. It is unfortunate that these actions were required. The MySQL mailing lists are a shared resource for the global MySQL community. While we are fortunate to have members from many or all of the wired countries in the world, it means that it is almost inevitable that there will occasionally be fundamental differences of belief between list members. We ask people to avoid these conflicts and instead focus on the co-operative and community aspects of the list. To help maintain the MySQL lists as a friendly, helpful and useful resource, we must request that people *do not respond to off-topic posts*. If you do feel compelled to respond, please do so off of the mailing list. If you find a post to be offensive, please notify our list administrators at [EMAIL PROTECTED] - we will deal with the situation as best we can. If you wish to discuss this situation further, please mail me *off-list* at [EMAIL PROTECTED] Yours Truly, Zak Greant MySQL Community Advocate - 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?

Re: Year data type

Hello Sean, I don't speak for Monty here, but I would guess that you have hit the nail on the head. The years 1901-2155 are useful for a large segment of user data. Being able to store year information for account expiry dates, etc. in a single byte can be a considerable space savings when looking at a large database. This range of values could be represented by a TINYINT - however, this would require extra logic to conver the TINYINT to a year value. If you want to store years outside the range of YEAR, use the SMALLINT data type - it allows you to easily represent the years 32768 BC to 32767 AD. -- Zak Greant [EMAIL PROTECTED] | MySQL Advocate | http://zak.fooassociates.com MySQL Tip: Connect to a remote MySQL server using the mysql client % mysql --host=example.com --user=admin -p Public Service Announcement: Open Source Initiative (http://www.opensource.org) - 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?

Re: converting text to hypertext

Good Day Rick! There is no hypertext/hyperlink data type and I do not know of any plans for one. A simple bit of shell scripting like: mysql -e SELECT something FROM somewhere -H |\ sed -e 's/http:\/\/[^ ]\+/a href=\/a/' should replace all of the valid http URLs in your HTML tables with anchors.

Re: Row value uniqueness?
On Wed, Jan 08, 2003 at 10:27:30AM -0800, Steven Nakhla wrote: Aside from designating a row as a primary key, is their any SQL syntax to force that entries within a row are unique (such as a string value)? Thanks! Hello Steve, You can create a UNIQUE key for a column that will ensure that all values entered into the column are unique. i.e. CREATE TABLE foo ( ..., ..., UNIQUE (...) ) If you truly want to ensure that a row is unique, then you can create a UNIQUE key that contains all of the columns in a table. This will allow you to enter duplicate values within the columns, but the combination of values (in this case, an entire row) must be unique. i.e. CREATE TABLE combolock ( tumbler_1 INT NOT NULL, tumbler_2 INT NOT NULL, tumbler_3 INT NOT NULL, UNIQUE tumblers (tumbler_1, tumbler_2, tumbler_3) ) mysql INSERT INTO combolock VALUES (1,1,1); Query OK, 1 row affected (0.00 sec) mysql INSERT INTO combolock VALUES (1,1,1); ERROR 1062: Duplicate entry '1-1-1' for key 1 mysql INSERT INTO combolock VALUES (1,1,2); Query OK, 1 row affected (0.00 sec) Cheers! -- Zak Greant [EMAIL PROTECTED] | MySQL Advocate | http://zak.fooassociates.com Using and Managing MySQL MySQL Training: Stockholm, February 24-28, 2003 Visit http://mysql.com/training for more information While we are postponing, life speeds by.--Lucius Annaeus Seneca - 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?
