  • Segmentation fault on login to mysql

    - by numberwhun
    Hello everyone! I recently did a fresh install of Ubuntu on my laptop (HP dv7, AMD Dual Core with 4 gigs RAM). I am working on installing my development environment and tools and one of the first things I was working on is getting MySQL installed. The following was my configure statement with options: ./configure --prefix=/usr/local/mysql --with-big-tables --with-unix-socket-path=/usr/local/mysql/tmp/mysql.sock --with-named-curses-libs=/lib/libncurses.so.5.7 After I did the make;make install, I did the post configuration such as setting the root password and installing the mysqld daemon in its rightful place. My issue is when I try to log in to mysql to start using it, the following shows what happens: $ mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 1 Server version: 5.1.42 Source distribution Segmentation fault I have searched Google extensively, I have searched through the mysql bugs database and I have yet to find anything that matches my issue. Here is the contents of my my.cnf file, in case you want to see it: $ cat /etc/my.cnf [mysqld] basedir=/usr/local/mysql datadir=/usr/local/mysql socket=/usr/local/mysql/tmp/mysql.sock [mysql.server] user=mysql #basedir=/var/lib [client] socket=/usr/local/mysql/tmp/mysql.sock [mysqld_safe] err-log=/usr/local/mysql/logs/mysqld.log pid-file=/var/run/mysqld/mysqld.pid I am really hoping that someone here can tell me what has gone wrong with my installation as I would really love to know. I welcome and look forward to all responses. Thank you in advance! Best regards, Jeff

  • General logging won't work in MySQL

    - by leonstr
    I saw on SF that there's an option in MySQL to log all queries. So, in my version (mysql-server-5.0.45-7.el5 on CentOS 5.2) this appears to be a case of enabling the 'log' option, so I edited /etc/my.cnf to add this: [mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock user=mysql old_passwords= log=/var/log/mysql-general.log [mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid I then created the file and set permissions: # touch /var/log/mysql-general.log # chown mysql. /var/log/mysql-general.log # ls -l /var/log/mysql-general.log -rw-r--r-- 1 mysql mysql 0 Jan 18 15:22 /var/log/mysql-general.log But when I start mysqld I get: 120118 15:24:18 mysqld started ^G/usr/libexec/mysqld: File '/var/log/mysql-general.log' not found (Errcode: 13) 120118 15:24:18 [ERROR] Could not use /var/log/mysql-general.log for logging (error 13). Turning logging off for the whole duration of the MySQL server process. To turn it on again: fix the cause, shutdown the MySQL server and restart it. 120118 15:24:18 InnoDB: Started; log sequence number 0 182917764 120118 15:24:18 [Note] /usr/libexec/mysqld: ready for connections. Can anyone suggest why this isn't working?

  • Installing MySQL 5.1 on OS X 10.7 Lion

    - by xisal
    I am trying to install MySQL 5.1. I am on Lion, and when I remove all files associated with MySQL on my machine it still tells me that I have a newer version installed when I try to install it from the DMG file. Has anyone successfully installed MySQL 5.1 on Lion? I found a solution using Homebrew: Completely remove MySQL from your system (just in case) sudo rm /usr/local/mysql sudo rm -rf /usr/local/mysql* sudo rm -rf /Library/StartupItems/MySQLCOM sudo rm -rf /Library/PreferencePanes/My* vim /etc/hostconfig and removed the line MYSQLCOM=-YES- rm -rf ~/Library/PreferencePanes/My* sudo rm -rf /Library/Receipts/mysql* sudo rm -rf /Library/Receipts/MySQL* sudo rm -rf /var/db/receipts/com.mysql.* Source:http://stackoverflow.com/questions/1436425/how-do-you-uninstall-mysql-from-mac-os-x Install homebrew /usr/bin/ruby -e "$(curl -fsSL https://raw.github.com/gist/323731)" Source: https://github.com/mxcl/homebrew/wiki/installation Install MySQL 5.1 via brew brew install mysql51 if that doesn't work, do this: brew install https://raw.github.com/adamv/homebrew-alt/master/versions/mysql51.rb Source: http://stackoverflow.com/questions/4359131/brew-install-mysql-on-mac-os/6399627#6399627 Make MySQL Work Create mysql.sock file touch /tmp/mysql.sock Install MySQL default tables /usr/local/Cellar/mysql51/5.1.58/bin/mysql_install_db ...or your path Source: http://stackoverflow.com/questions/4788381/getting-cant-connect-through-socket-tmp-mysql-when-installing-mysql-on-ma/5140849#5140849

  • Webserver: chrooted PHP gives mysql.sock error when attempting to reach mysql

    - by Jon L.
    Hey guys, I've configured an Ubuntu webserver with Nginx + PHP5-FPM. I've created a chrooted environment (using jailkit) that I'm tossing my developers into, from where they can develop their test applications. Chroot jail: /home/jail Nginx and PHP5-FPM run outside the chroot, but are configured to function with websites within the chrooted environment. So far, Nginx and PHP5-FPM are serving up files without issue, except for the following: When attempting to connect to MySQL, we receive this error: SQLSTATE[HY000] [2002] Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' Now, I believe the issue is due to the non-chrooted php.ini referencing mysqld.sock outside of the chroot environment (it's actually using the MySQL default setting currently). My question is, how can I configure PHP to access MySQL via loopback or similar? (Found that as a suggestion in a google result, but without any instructions) Or if I'm missing some other obvious setting, let me know. If there's an option of creating a hardlink (that would remain available even if mysql is restarted), that would be handy as well.

  • Installing MySQL 5.5 manually on Ubuntu 10.04 server, errors about "/tmp/mysql.sock"

    - by black sensei
    I've set up an Ubuntu server and wanted to install MySQL 5.5. I've been following these MySQL documentation steps. I have libaio dev installed. Everything went fine until I ran bin/mysqld_safe --user=mysql & It runs into an issue and never returns to the shell. The output of mysqld_safe is logging to /usr/local/mysql/data/host_name.err. When I checked that file, it was complaining about /tmp/mysql.sock. I can unfortunately describe just parts of the error, since before I started right now it deleted all the files I've started installing back then by mistake. Should I change the socket to /var/run/mysqld/mysqld.socket after copying the .cnf file to /etc? I've also checked the /var/run/mysqld directory and there is no mysqld.socket. How do I proceed? Thanks for reading this and helping out

  • MS SQL to MySQL using MySQL Migration Toolkit: permission issue

    - by Zeno
    I have a MS SQL imported into SQL Server 2008 from a .bak and I set it to Mixed mode. I have a SQL user (called "test") that can correctly access the database using SQL Server. I need to convert this to a MySQL database, so I got the MySQL Migration Toolkit. I pick "MS SQL Server" and then it asks for the hostname/username/password/database. I'm not 100% sure on these, but I used "localhost" (running on same computer), left the port as is (1433) and the username/password ("test") for the SQL Server. And I used the database name for the SQL Server database I'm looking to import. I clicked next, enter my MySQL database details and then attempt to run it and I get this error: Connecting to source database and retrieve schemata names. Initializing JDBC driver ... Driver class MS SQL JDBC Driver Opening connection ...

  • How to easily upgrade MySQL 5.0.32 to MySQL 5.1.20 or higher on Debian Etch?

    - by Ferdy
    I have a home server running Debian Etch with MySQL 5.0.32 on it. I'm not much of a Linux administrator but two years ago I installed the server and it runs fine. I used the official MySQL package for Debian at that time. Since then I have been happily making use of it. Now I need to use a MySQL function that is only available in MySQL 5.1.20 and higher. Therefore I would like to upgrade. I'm not that confident in messing with something I need every day so I wanted to check with you what the best upgrade path would be? Obviously I prefer a simple upgrade that keeps my database, users and settings in place as they are now.

  • New Replication, Optimizer and High Availability features in MySQL 5.6.5!

    - by Rob Young
    As the Product Manager for the MySQL database it is always great to announce when the MySQL Engineering team delivers another great product release.  As a field DBA and developer it is even better when that release contains improvements and innovation that I know will help those currently using MySQL for apps that range from modest intranet sites to the most highly trafficked web sites on the web.  That said, it is my pleasure to take my hat off to MySQL Engineering for today's release of the MySQL 5.6.5 Development Milestone Release ("DMR"). The new highlighted features in MySQL 5.6.5 are discussed here: New Self-Healing Replication ClustersThe 5.6.5 DMR improves MySQL Replication by adding Global Transaction Ids and automated utilities for self-healing Replication clusters.  Prior to 5.6.5 this has been somewhat of a pain point for MySQL users with most developing custom solutions or looking to costly, complex third-party solutions for these capabilities.  With 5.6.5 these shackles are all but removed by a solution that is included with the GPL version of the database and supporting GPL tools.  You can learn all about the details of the great, problem solving Replication features in MySQL 5.6 in Mat Keep's Developer Zone article.  New Replication Administration and Failover UtilitiesAs mentioned above, the new Replication features, Global Transaction Ids specifically, are now supported by a set of automated GPL utilities that leverage the new GTIDs to provide administration and manual or auto failover to the most up to date slave (that is the default, but user configurable if needed) in the event of a master failure. The new utilities, along with links to Engineering related blogs, are discussed in detail in the DevZone Article noted above. Better Query Optimization and ThroughputThe MySQL Optimizer team continues to amaze with the latest round of improvements in 5.6.5. Along with much refactoring of the legacy code base, the Optimizer team has improved complex query optimization and throughput by adding these functional improvements: Subquery Optimizations - Subqueries are now included in the Optimizer path for runtime optimization.  Better throughput of nested queries enables application developers to simplify and consolidate multiple queries and result sets into a single unit or work. Optimizer now uses CURRENT_TIMESTAMP as default for DATETIME columns - For simplification, this eliminates the need for application developers to assign this value when a column of this type is blank by default. Optimizations for Range based queries - Optimizer now uses ready statistics vs Index based scans for queries with multiple range values. Optimizations for queries using filesort and ORDER BY.  Optimization criteria/decision on execution method is done now at optimization vs parsing stage. Print EXPLAIN in JSON format for hierarchical readability and Enterprise tool consumption. You can learn the details about these new features as well all of the Optimizer based improvements in MySQL 5.6 by following the Optimizer team blog. You can download and try the MySQL 5.6.5 DMR here. (look under "Development Releases")  Please let us know what you think!  The new HA utilities for Replication Administration and Failover are available as part of the MySQL Workbench Community Edition, which you can download here .Also New in MySQL LabsAs has become our tradition when announcing DMRs we also like to provide "Early Access" development features to the MySQL Community via the MySQL Labs.  Today is no exception as we are also releasing the following to Labs for you to download, try and let us know your thoughts on where we need to improve:InnoDB Online OperationsMySQL 5.6 now provides Online ADD Index, FK Drop and Online Column RENAME.  These operations are non-blocking and will continue to evolve in future DMRs.  You can learn the grainy details by following John Russell's blog.InnoDB data access via Memcached API ("NotOnlySQL") - Improved refresh of an earlier feature releaseSimilar to Cluster 7.2, MySQL 5.6 provides direct NotOnlySQL access to InnoDB data via the familiar Memcached API. This provides the ultimate in flexibility for developers who need fast, simple key/value access and complex query support commingled within their applications.Improved Transactional Performance, ScaleThe InnoDB Engineering team has once again under promised and over delivered in the area of improved performance and scale.  These improvements are also included in the aggregated Spring 2012 labs release:InnoDB CPU cache performance improvements for modern, multi-core/CPU systems show great promise with internal tests showing:    2x throughput improvement for read only activity 6x throughput improvement for SELECT range Read/Write benchmarks are in progress More details on the above are available here. You can download all of the above in an aggregated "InnoDB 2012 Spring Labs Release" binary from the MySQL Labs. You can also learn more about these improvements and about related fixes to mysys mutex and hash sort by checking out the InnoDB team blog.MySQL 5.6.5 is another installment in what we believe will be the best release of the MySQL database ever.  It also serves as a shining example of how the MySQL Engineering team at Oracle leads in MySQL innovation.You can get the overall Oracle message on the MySQL 5.6.5 DMR and Early Access labs features here. As always, thanks for your continued support of MySQL, the #1 open source database on the planet!

  • mysql master-slave setup with synchronous replication

    - by imaginative
    I have a very trivial mysql master-slave setup going on between two servers. The problem is, replication is asynchronous, and this can cause issues (even on a low latency link), if the master server was to crash after a COMMIT before the replication thread from the slave was able to fetch the last bin log. Is there anyway to force mysql to do synchronous commits so that data consistency is guaranteed in a mysql-slave relationship?

  • Java-JDBC-MySQL Error

    Oracle MySQL Engineer Ulf Wendel delivered yesterday a talk about his Proof of Concept at the International PHP Conference in Berlin entitled: “HTTP, JSON, JavaScript, Map and Reduce built-in to MySQL - make it happen, today.” The presentation has been featured today on the home page of SlideShare, both into the “Hot on Facebook” and “Hot on Twitter” sections. Well done, Ulf! Especially just before the wedding…:) Presentation abstract: See how a MySQL Server plugin can be developed to build all this into MySQL. A new direct wire between MySQL and client-side JavaScript is created. MySQL speaks HTTP, replies JSON and offers server-side JavaScript. Server-side JavaScript gets access to MySQL data and does Map&Reduce of JSON documents stored in MySQL. Fast? 2-4x faster than proxing client-side JavaScript request through PHP/Apache. Reasonable results... Slides available here. And, talking about innovation… today is Oracle’s MySQL Innovation Day, you can still attend the event online. Register Now, it starts at 9.00 am PT.

  • MySQL – Scalability on Amazon RDS: Scale out to multiple RDS instances

    - by Pinal Dave
    Today, I’d like to discuss getting better MySQL scalability on Amazon RDS. The question of the day: “What can you do when a MySQL database needs to scale write-intensive workloads beyond the capabilities of the largest available machine on Amazon RDS?” Let’s take a look. In a typical EC2/RDS set-up, users connect to app servers from their mobile devices and tablets, computers, browsers, etc.  Then app servers connect to an RDS instance (web/cloud services) and in some cases they might leverage some read-only replicas.   Figure 1. A typical RDS instance is a single-instance database, with read replicas.  This is not very good at handling high write-based throughput. As your application becomes more popular you can expect an increasing number of users, more transactions, and more accumulated data.  User interactions can become more challenging as the application adds more sophisticated capabilities. The result of all this positive activity: your MySQL database will inevitably begin to experience scalability pressures. What can you do? Broadly speaking, there are four options available to improve MySQL scalability on RDS. 1. Larger RDS Instances – If you’re not already using the maximum available RDS instance, you can always scale up – to larger hardware.  Bigger CPUs, more compute power, more memory et cetera. But the largest available RDS instance is still limited.  And they get expensive. “High-Memory Quadruple Extra Large DB Instance”: 68 GB of memory 26 ECUs (8 virtual cores with 3.25 ECUs each) 64-bit platform High I/O Capacity Provisioned IOPS Optimized: 1000Mbps 2. Provisioned IOPs – You can get provisioned IOPs and higher throughput on the I/O level. However, there is a hard limit with a maximum instance size and maximum number of provisioned IOPs you can buy from Amazon and you simply cannot scale beyond these hardware specifications. 3. Leverage Read Replicas – If your application permits, you can leverage read replicas to offload some reads from the master databases. But there are a limited number of replicas you can utilize and Amazon generally requires some modifications to your existing application. And read-replicas don’t help with write-intensive applications. 4. Multiple Database Instances – Amazon offers a fourth option: “You can implement partitioning,thereby spreading your data across multiple database Instances” (Link) However, Amazon does not offer any guidance or facilities to help you with this. “Multiple database instances” is not an RDS feature.  And Amazon doesn’t explain how to implement this idea. In fact, when asked, this is the response on an Amazon forum: Q: Is there any documents that describe the partition DB across multiple RDS? I need to use DB with more 1TB but exist a limitation during the create process, but I read in the any FAQ that you need to partition database, but I don’t find any documents that describe it. A: “DB partitioning/sharding is not an official feature of Amazon RDS or MySQL, but a technique to scale out database by using multiple database instances. The appropriate way to split data depends on the characteristics of the application or data set. Therefore, there is no concrete and specific guidance.” So now what? The answer is to scale out with ScaleBase. Amazon RDS with ScaleBase: What you get – MySQL Scalability! ScaleBase is specifically designed to scale out a single MySQL RDS instance into multiple MySQL instances. Critically, this is accomplished with no changes to your application code.  Your application continues to “see” one database.   ScaleBase does all the work of managing and enforcing an optimized data distribution policy to create multiple MySQL instances. With ScaleBase, data distribution, transactions, concurrency control, and two-phase commit are all 100% transparent and 100% ACID-compliant, so applications, services and tooling continue to interact with your distributed RDS as if it were a single MySQL instance. The result: now you can cost-effectively leverage multiple MySQL RDS instance to scale out write-intensive workloads to an unlimited number of users, transactions, and data. Amazon RDS with ScaleBase: What you keep – Everything! And how does this change your Amazon environment? 1. Keep your application, unchanged – There is no change your application development life-cycle at all.  You still use your existing development tools, frameworks and libraries.  Application quality assurance and testing cycles stay the same. And, critically, you stay with an ACID-compliant MySQL environment. 2. Keep your RDS value-added services – The value-added services that you rely on are all still available. Amazon will continue to handle database maintenance and updates for you. You can still leverage High Availability via Multi A-Z.  And, if it benefits youra application throughput, you can still use read replicas. 3. Keep your RDS administration – Finally the RDS monitoring and provisioning tools you rely on still work as they did before. With your one large MySQL instance, now split into multiple instances, you can actually use less expensive, smallersmaller available RDS hardware and continue to see better database performance. Conclusion Amazon RDS is a tremendous service, but it doesn’t offer solutions to scale beyond a single MySQL instance. Larger RDS instances get more expensive.  And when you max-out on the available hardware, you’re stuck.  Amazon recommends scaling out your single instance into multiple instances for transaction-intensive apps, but offers no services or guidance to help you. This is where ScaleBase comes in to save the day. It gives you a simple and effective way to create multiple MySQL RDS instances, while removing all the complexities typically caused by “DIY” sharding andwith no changes to your applications . With ScaleBase you continue to leverage the AWS/RDS ecosystem: commodity hardware and value added services like read replicas, multi A-Z, maintenance/updates and administration with monitoring tools and provisioning.

Has something changed with the latest OpenSSL? Any help would be appreciated!

  • Megjelent a MySQL 5.5

    - by Lajos Sárecz
    Rekord ido alatt készült el az új MySQL 5.5 verziót, melyet a mai nap jelentett be az Oracle. Ez újabb bizonyítéka annak, hogy az Oracle komolyan fejleszti a MySQL-t is, és igyekszik innovatív megoldásokkal megörvendeztetni a MySQL felhasználókat is. Akinek 'Déja-vu' érzése van, az nem véletlen, hiszen a szeptemberi OpenWorld konferencián került bejelentésre a MySQL 5.5 RC, azaz a Release Candidate, melyrol beszámolt például a hwsw.hu is. Az új verzióban elsosorban a teljesítményen és a skálázhatóságon fejlesztett az Oracle. Így például alapértelmezetten az InnoDB storage engine jön a MySQL-el, aminek köszönhetoen például ACID (atomicity, consistency, isolation, durability) tranzakciókat hajt végre az adatbázis-kezelo (ez mondjuk nem egy apró részlet...). Emellett újdonságot jelent még a majdnem szinkron replikáció, a fejlettebb index és tábla particionálás, valamint diagnosztika terén bevezetésre került egy új PERFORMANCE_SCHEMA, aminek köszönhetoen javult a MySQL menedzselhetosége. A RC verzióval futtatott tesztek jelentos gyorsulást mutattak a MySQL 5.1-es verziójához képest, így érdemes megfontolni a verzió frissítést.

  • Oracle üzleti intelligencia és MySQL adatforrás

    - by Fekete Zoltán
    A tegnap Oracle sajtóhír a következo bejelentésrol szól: megjelent a MySQL Cluster 7.1 új verziója. Ez is az Oracle elkötelezettségét jelzi a MySQL fejlesztése és az Open Source mellett. A témáról nemrég irt a HWSW a következo cikkben: Az Oracle betekintést engedett a MySQL jövojébe. Idézetek a cikkbol: "Santa Clarában az O'Reilly MySQL Conference and Expo rendezvényen személyesen az Oracle fomérnöke, Edward Screven beszélt arról, milyen jövot szánnak a MySQL-nek." "Screven igyekezett megerosíteni az Oracle korábbi vállalásait. "Továbbra is fejleszteni és javítani és támogatni fogjuk a MySQL-t" - szögezte le a fomérnök..." Miért is érdekes ez? Azért mert Oracle Business Intelligence csomagok egyik adatforrása a MySQL adatbázis. Azért mert az Oracle BI csomagok lelke, az Oracle BI Server egyedülállóan jól integrál heterogén adatforrásokat, mindezt egyetlen közös üzleti metaadat réteggel! Többek között erre nem képesek más szállítók.

  • Cant connect to MySQL server from Java application

    - by RN
    This is on VPS\Centos server. The MySQL server is pre configured. I am running the Java application on Tomcat My Java web application is not able to connect to the MySQL server. I get an error - "Caused by: java.net.ConnectException: Connection refused" I suspect this to be a configuration problem rather than a coding problem- hence I have posted this on ServerFault And yes, The same web-app is able to connect to MySQL on a different linux box This is the URL that I provided to my Java application (note- it assumes default port) url = "jdbc:mysql://localhost/pickupgames" My first suspicion was that I am running on a non-default port So I tried to find the port where mySQL server is running I tried every trick mentioned in http://serverfault.com/questions/116100/how-to-check-what-port-mysql-is-running-on But no luck ! SHOW GLOBAL VARIABLES LIKE 'PORT'; This shows port 0 netstat -tlnp doesn't show mysql at all /etc/my.cnf It has no port entry telnet localhost 3306 Doesn't connect And in case you are wondering if mysql server is running at all or not It is And I know for sure, because I have been able to login using the mysql command Also # ps -ef|grep 'mysql' root 31839 27662 0 00:49 pts/3 00:00:00 grep mysql root 32452 1 0 Apr02 ? 00:00:00 /bin/sh /usr/bin/mysqld_safe --skip-grant-tables --skip-networking mysql 32504 32452 0 Apr02 ? 00:00:06 /usr/libexec/mysqld --basedir=/usr --datadir=/var/lib/mysql --user=mysql --pid-file=/var/run/mysqld/mysqld.pid --skip-external-locking --socket=/var/lib/mysql/mysql.sock --skip-grant-tables --skip-networking Please note the --skip-networking parameter Does this have something to do with the issue ? Any explanation why I cant connect to mysql server on port 3306 by telnet? Or why it docent show up under netstat? Any suggestion on whet I should try next ?

  • Mysql my.cnf as simbolic link in Ubuntu 12.04

    - by Juan Cruz
    I am not able to use symlink for my.cnf file (Ubuntu 12.04 server). I added the alias to /etc/apparmor.d/tunables/alias file (as I did for 10.04 and worked) but I get: May 30 16:00:01 ip-10-242-209-203 kernel: [176926.213403] type=1400 audit(1338393601.350:244): apparmor="DENIED" operation="open" parent=1 profile="/usr/sbin/mysqld" name="/opt/data/my.cnf" pid=18128 comm="mysqld" requested_mask="r" denied_mask="r" fsuid=0 ouid=0 May 30 16:00:01 ip-10-242-209-203 kernel: [176926.222016] init: mysql main process (18128) terminated with status 1 May 30 16:00:01 ip-10-242-209-203 kernel: [176926.222084] init: mysql respawning too fast, stopped As a workaround I added the following line /etc/mysql/my.cnf r, to the /etc/apparmor.d/local/usr.sbin.mysqld file. The default configuration is /etc/mysql/*.cnf r, Is this a bug? is an apparmor bug or a mysql bug? It seems that that configuration has changed since MySql 5.1 (https://bugs.launchpad.net/ubuntu/+source/mysql-5.1/+bug/619172) but now worked for me. Thanks!

  • study materials for Mysql certification?

    - by Andre
    I'm preparing for Mysql certification, nowadays officially titled: Oracle Certified Professional, MySQL 5.0 Developer certification After looking through Mysql forum it looks like most people recommended this book: http://www.amazon.com/MySQL-5-0-Certification-Study-Guide/dp/0672328127/ref=sr_1_1?ie=UTF8&qid=1299972594&sr=8-1 Which as far as I learned - was the official preparation source at the time when Mysql was controlled by Mysql AB and Sun. Now, however - Oracle officially doesn't recommend this book. to be precise - I don't now what they recommend. I could only find this "value package":( http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=532 Can someone who got mysql certification confirm that this book is what they have used? Also -If there is any other moderately priced study materials out there - plz let me know. Thanks P.s. mods - feel free to kick this question into more suitable site.:)
