  • How To Backup Of MySQL Database Using PhpMyAdmin

    - by Jyoti
    It is very important to do backup of your MySql database, you will probably realize it when it is too late. A lot of web applications use MySql for storing the content. This can be blogs, and a lot of other things. When you have all your content as html files on your web server it is very easy to keep them safe from crashes, you just have a copy of them on your own PC and then upload them again after the web server is restored after the crash. All the content in the MySql database must also be backed up. If you have spent a lot of time making the content and it is only stored in the Mysql server, you will feel very bad if it gets lost for ever. Backing it up once every month or so makes sure you never loose too much of your work in case of a server crash, and it will make you sleep better at night. It is easy and fast, so there is no reason for not doing it. Step 1: Log into phpMyAdmin on your server. Step2: You can select the database that you would like to backup from the drop-down menu called Database. Step 3: A new page will be loaded in phpMyAdmin showing the selected database. In order to proceed with the backup click on the Export tab. Step 4: The options that you should select apart from the default ones are Save as file which will save the file locally to your computer in an .sql format and Add DROP TABLE which will add the drop table functionality if the table already exists in the database backup as shown below. Step 5: Click on the Go button to start the export/backup procedure for your database. A download window will pop up prompting for the exact place where you would like to save the file on your local computer. It is possible that the download starts automatically. This depends on your browser’s settings.

  • is mysql index useful on column 'state' when only doing bit-operations on the column?

    - by Geert-Jan
    I have a lot of domain entities (stored in mysql) which undergo lots of different operations. Each operation is executed from a different program. I need to keep (flow)-state for these entities which I implemented in as a long field 'flowstate' used as a bitset. to query mysql for entities which have undergone a certain operation I do something like: select * from entities where state >> 7 & 1 = 1 Indicating bit 7 (cooresponding to operation 7) has run. (<-- simplified) Anyway, I really didn't pay attention to the performance implications of this setup in the beginning, and I think I'm in a bit of trouble since queries as the above run pretty slow. What I'd like to know: Does an mysql index on 'flowstate' help at all? After all it's not a single value Mysql can quickly find using a binary sort or whatever. If it doesn't, are there any other things I could do to speed things up? . Are there special 'mask-indices' for fields with use-cases as the above? TIA, Geert-jan

  • How can I get back my privilege to create a new database in MySQL?

    - by Steven
    I can not use MySQL. MySQL is on my local computer. Currently I added skip-grant-tables in My.ini so I can use MySQL. But I have no privilege to create a new database. My problem is tough, although I asked related questions on SO, but no answer can resolve my problem. I almost give up. So I lower my expectation. I am developing a website, so I need to create database, tables and operate tables. You don't have to consider security. Is there a simple solution that can give me privilege to create a new database? Maybe by adding some command in my.ini or something? You won't need to completely resolve my problem. Maybe after the development, I will upload the database and tables to another server(The current database server is my personal computer, windows XP) so I can uninstall and reinstall MySQL. The root of problem is that I lack privileges.

  • How do I get PHP variables from this MySQL query?

    - by CT
    I am working on an Asset Database problem using PHP / MySQL. In this script I would like to search my assets by an asset id and have it return all related fields. First I query the database asset table and find the asset's type. Then depending on the type I run 1 of 3 queries. <?php //make database connect mysql_connect("localhost", "asset_db", "asset_db") or die(mysql_error()); mysql_select_db("asset_db") or die(mysql_error()); //get type of asset $type = mysql_query(" SELECT asset.type From asset WHERE asset.id = 93120 ") or die(mysql_error()); switch ($type){ case "Server": //do some stuff that involves a mysql query mysql_query(" SELECT asset.id ,asset.company ,asset.location ,asset.purchase_date ,asset.purchase_order ,asset.value ,asset.type ,asset.notes ,server.manufacturer ,server.model ,server.serial_number ,server.esc ,server.user ,server.prev_user ,server.warranty FROM asset LEFT JOIN server ON server.id = asset.id WHERE asset.id = 93120 "); break; case "Laptop": //do some stuff that involves a mysql query mysql_query(" SELECT asset.id ,asset.company ,asset.location ,asset.purchase_date ,asset.purchase_order ,asset.value ,asset.type ,asset.notes ,laptop.manufacturer ,laptop.model ,laptop.serial_number ,laptop.esc ,laptop.user ,laptop.prev_user ,laptop.warranty FROM asset LEFT JOIN laptop ON laptop.id = asset.id WHERE asset.id = 93120 "); break; case "Desktop": //do some stuff that involves a mysql query mysql_query(" SELECT asset.id ,asset.company ,asset.location ,asset.purchase_date ,asset.purchase_order ,asset.value ,asset.type ,asset.notes ,desktop.manufacturer ,desktop.model ,desktop.serial_number ,desktop.esc ,desktop.user ,desktop.prev_user ,desktop.warranty FROM asset LEFT JOIN desktop ON desktop.id = asset.id WHERE asset.id = 93120 "); break; } ?> So far I am able to get asset.type into $type. How would I go about getting the rest of the variables (laptop.model to $model, asset.notes to $notes and so on)? Thank you.

  • Is it a good idea to use MySQL and Neo4j together?

    - by Sanoj
    I will make an application with a lot of similar items (millions), and I would like to store them in a MySQL database, because I would like to do a lot of statistics and search on specific values for specific columns. But at the same time, I will store relations between all the items, that are related in many connected binary-tree-like structures (transitive closure), and relation databases are not good at that kind of structures, so I would like to store all relations in Neo4j which have good performance for this kind of data. My plan is to have all data except the relations in the MySQL database and all relations with item_id stored in the Neo4j database. When I want to lookup a tree, I first search the Neo4j for all the item_id:s in the tree, then I search the MySQL-database for all the specified items in a query that would look like: SELECT * FROM items WHERE item_id = 45 OR item_id = 345435 OR item_id = 343 OR item_id = 78 OR item_id = 4522 OR item_id = 676 OR item_id = 443 OR item_id = 4255 OR item_id = 4345 Is this a good idea, or am I very wrong? I haven't used graph-databases before. Are there any better approaches to my problem? How would the MySQL-query perform in this case?

  • What's the best way to get a bunch of rows from MySQL if you have an array of integer primary keys?

    - by Evan P.
    I have a MySQL table with an auto-incremented integer primary key. I want to get a bunch of rows from the table based on an array of integers I have in memory in my program. The array ranges from a handful to about 1000 items. What's the most efficient query syntax to get the rows? I can think of a few: "SELECT * FROM thetable WHERE id IN (1, 2, 3, 4, 5)" (this is what I do now) "SELECT * FROM thetable where id = 1 OR id = 2 OR id = 3" Multiple queries of the form "SELECT * FROM thetable WHERE id = 1". Probably the most friendly to the query cache, but expensive due to having lots of query parsing. A union, like "SELECT * FROM thetable WHERE id = 1 UNION SELECT * FROM thetable WHERE id = 2 ..." I'm not sure if MySQL caches the results of each query; it's also the most verbose format. I think using the NoSQL interface in MySQL 5.6+ would be the most efficient way to do this, but I'm not yet up to MySQL 5.6.

  • [PHP] MySql Proccesslist filled with "Sleep" Entries leading to "To many Connections" ?

    - by edorian
    Hi, i'd like to ask your help on a longstanding issue with php/mysql connections. Every time i execute a "SHOW PROCESSLIST" command it shows me about 400 idle (Status: Sleep) connections to the database Server emerging from our 5 Webservers. That never was much of a problem (and i didn't find a quick solution) until recently traffic numbers increased and since then MySql reports the "to many connections" Problems repeatedly, even so 350+ of those connections are in "sleep" state. Also a server can't get a mysql connection even if there are sleeping connection to that same server. All those connections vanish when a apache server is restated. The PHP Code used to create the Database connections uses the normal "mysql" Module, the "mysqli" Module, PEAR::DB and Zend Framework Db Adapter. (Different projects). NONE of the projects uses persistent connections. Raising the connection-limit is possible but doesn't seem like a good solution since it's 450 now and there are only 20-100 "real" connections at a time anyways. My question: Why are there so many connections in sleep state and how can i prevent that. Thank you for your time, if theres anything unclear or missing please let me know

  • jdbc4 CommunicationsException

    - by letronje
    I have a machine running a java app talking to a mysql instance running on the same instance. the app uses jdbc4 drivers from mysql. I keep getting com.mysql.jdbc.exceptions.jdbc4.CommunicationsException at random times. Here is the whole message. Could not open JDBC Connection for transaction; nested exception is com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: The last packet successfully received from the server was25899 milliseconds ago.The last packet sent successfully to the server was 25899 milliseconds ago, which is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem. For mysql, the value of global 'wait_timeout' and 'interactive_timeout' is set to 3600 seconds and 'connect_timeout' is set to 60 secs. the wait timeout value is much higher than the 26 secs(25899 msecs). mentioned in the exception trace. I use dbcp for connection pooling and here is spring bean config for the datasource. <bean id="dataSource" destroy-method="close" class="org.apache.commons.dbcp.BasicDataSource" > <property name="driverClassName" value="com.mysql.jdbc.Driver"/> <property name="url" value="jdbc:mysql://localhost:3306/db"/> <property name="username" value="xxx"/> <property name="password" value="xxx" /> <property name="poolPreparedStatements" value="false" /> <property name="maxActive" value="3" /> <property name="maxIdle" value="3" /> </bean> Any idea why this could be happening?

  • mysql_query missing during installation

    - by Arsenal
    Hi, I'm trying to install the pdo_mysql extension... I managed to install it succesfully, but ever since I upgraded mysql to 5.1.34 (using rpm packages) it seems to have gone down so I tried to reinstall it. However it seems to crash on ./configure as it gives 'mysql_query not found' error: configure:3961: checking for mysql_query in -lmysqlclient configure:3991: gcc -o conftest -g -O2 -I/usr/local/include/php -Wl,- rpath,/usr/lib/mysql -L/usr/lib/mysql -lmysqlclient -lz -lcrypt -lnsl -lm -lmygcc conftest.c -lmysqlclient -rdynamic -L/usr/lib/mysql -lmysqlclient -lz -lcrypt -lnsl -lm - lmygcc >&5 /usr/bin/ld: skipping incompatible /usr/lib/mysql/libmysqlclient.a when searching for -lmysqlclient /usr/bin/ld: skipping incompatible /usr/lib/mysql/libmysqlclient.a when searching for -lmysqlclient /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-redhat-linux/3.4.6/../../../libmysqlclient.so when searching for -lmysqlclient /usr/bin/ld: skipping incompatible /usr/lib/libmysqlclient.so when searching for -lmysqlclient /usr/bin/ld: cannot find -lmysqlclient collect2: ld returned 1 exit status configure:3997: $? = 1 configure: failed program was: | /* confdefs.h. */ ... In that file there seems to be a mysql_query(); statement. I'm pretty sure mysql_query works however since all of my websites are running normally. However the current setup is a mess (previous students kind of messed it up) and there are a whole lot of libmysqclient's in /etc: libmysqlclient.so.10.0.0 libmysqlclient.so.12.0.0 libmysqlclient.so.14.0.0 libmysqlclient.so.15.0.0 libmysqlclient.so.16.0.0 libmysqlclient_r.so.10.0.0 libmysqlclient_r.so.12.0.0 libmysqlclient_r.so.14.0.0 libmysqlclient_r.so.15.0.0 libmysqlclient_r.so.16.0.0 And just as much symlinks. Does anyone know how to get this right? Many thanks! (oh, and no pecl install pdo_mysql doesn't get me any further). I'm runnnig CentOS 4 with php 5.2.9 compiled from source and MySQL 5.1.34

  • Error when plugging iPod Touch into MacBook

    - by Mr. Man
    Whenever I plug my iPod Touch (2nd gen) into my MacBook running Ubuntu 10.10 I get the following error: DBus error org.freedesktop.DBus.Error.NoReply: Message did not receive a reply (timeout by message bus) It will show up in the file browser but whenever I try to mount it I get that error. EDIT: I thought that this might be because I had it plugged into a dock, but I tried plugging it in directly to the MacBook with the USB Cable and it still does not work, same error message.

  • MySQL Utility Users' Console Oerview

    - by rudrap
    MySQL Utility Users' Console (mysqluc): The MySQL Utilities Users' Console is designed to make using the utilities easier via a dedicated console. It helps us to use the utilities without worrying about the python and utility paths. Why do we need a special console? - It does provide a unique shell environment with command completion, help for each utility, user defined variables, and type completion for options. - You no longer have to type out the entire name of the utility. - You don't need to remember the name of a database utility you want to use. - You can define variables and reuse them in your utility commands. - It is possible to run utility command along with mysqluc and come out of the mysqluc console. Console commands: mysqluc> help Command Description ----------------------           --------------------------------------------------- help utilities                     Display list of all utilities supported. help <utility>                  Display help for a specific utility. help or help commands   Show this list. exit or quit                       Exit the console. set <variable>=<value>  Store a variable for recall in commands. show options                   Display list of options specified by the user on launch. show variables                 Display list of variables. <ENTER>                       Press ENTER to execute command. <ESCAPE>                     Press ESCAPE to clear the command entry. <DOWN>                       Press DOWN to retrieve the previous command. <UP>                               Press UP to retrieve the next command in history. <TAB>                            Press TAB for type completion of utility, option,or variable names. <TAB><TAB>                Press TAB twice for list of matching type completion (context sensitive). How do I use it? Pre-requisites: - Download the latest version of MySQL Workbench. - Mysql Servers are running. - Your Pythonpath is set. (e.g. Export PYTHONPATH=/...../mysql-utilities/) Check the Version of mysqluc Utility: /usr/bin/python mysqluc.py –version It should display something like this MySQL Utilities mysqluc.py version 1.1.0 - MySQL Workbench Distribution 5.2.44 Copyright (c) 2010, 2012 Oracle and/or its affiliates.

  • Entry / JR Php Programmer - What do I learn next?

    - by dtj
    I got very interested in programming toward the end of college. Took a few classes, but learned most everything on my own via books and such. Its mostly been Php and MySQL. Right out of school, I got a job working at a company for 2 years (web media) and ended up learning a lot of stuff and programming some things for them. I am no longer at that company but I am looking for my next steps as a programmer. I really enjoy Web Development and Php and MySQL seems to be my thing. Basically, I know how to do CRUD operations, i am mediocre at OOP and still have more to learn, I know HTML and CSS quite well, I know my way around a Unix terminal and can access MySQL through it and set up cron jobs and such. I know some basic Javascript. Whats a good next step? I don't anything about 3rd party services, PDO, APIs (twitter, facebook, etc), Drupal / Joomla, Unit Testing, E-Commerce, PECL, PEAR ....in other words A LOT I get easily overwhelmed by the amount of stuff there is to learn, so I'm sort of trying to find a path. Right now, I'm digging into OOP more, as that seems like a good conceptual first-step. Any suggestions?

  • How to design highly scalable web services in Java?

    - by Kshitiz Sharma
    I am creating some Web Services that would have 2000 concurrent users. The services are offered for free and are hence expected to get a large user base. In the future it may be required to scale up to 50,000 users. There are already a few other questions that address the issue like - Building highly scalable web services However my requirements differ from the question above. For example - My application does not have a user interface, so images, CSS, javascript are not an issue. It is in Java so suggestions like using HipHop to translate PHP to native code are useless. Hence I decided to ask my question separately. This is my project setup - Rest based Web services using Apache CXF Hibernate 3.0 (With relevant optimizations like lazy loading and custom HQL for tune up) Tomcat 6.0 MySql 5.5 My questions are - Are there alternatives to Mysql that offer better performance for what I'm trying to do? What are some general things to abide by in order to scale a Java based web application? I am thinking of putting my Application in two tomcat instances with httpd redirecting the request to appropriate tomcat on basis of load. Is this the right approach? Separate tomcat instances can help but then database becomes the bottleneck since both applications access the same database? I am a programmer not a Db Admin, how difficult would it be to cluster a Mysql database (or, to cluster whatever database offered as an alternative to 1)? How effective are caching solutions like EHCache? Any other general best practices? Some clarifications - Could you partition the data? Yes we could but we're trying to avoid it. We need to run a lot of data mining algorithms and the design would evolve over time so we can't be sure what lines of partition should be there.

  • LAMP setup - phpmyadmin says the mysqli extension is missing (but its listed in phpinfo)

    - by WebweaverD
    I regularly set up virtualbox ubuntu setups to run as local webservers. I have set these up several times and never had an issue. Recently I have been cloning them but wanted to do a fresh install this time in the hopes of fixing some niggling problems which have propagated through my setups. However, something has changed: 1)vb guest additions no longer allow me to copy and paste (i'll worry about that later) 2)more importantly phpmyadmin no longer works as installed - Initially going to localhost/phpmyadmin gave a message that the page could not be found. So I have followed some instructions (sorry I know its vague I cant find them now) which have created a phpmyadmin directory in /var/www but now I get an error saying: the mysqli extension is missing. If I run phpinfo mysql and mysqli are listed. All I have done so far is install apache2 (working) install php5 (which I think used to come with apache) Install mysql server (and client for good measure) and install phpmyadmin I found a post of a similar question which suggested I should install php5-mysql (done) and edit php.ini and uncomment the line extension-mysqli.so - this is not there, so I tried adding it with no joy. I have restarted apache and still no joy on phpmyadmin. Any help is much appreciated as this is driving me nuts. Why the change for the worse - I was just starting to like linux! I'm running a windows 7 machine and the guest os is ubuntu 12.04 - I ran apt-get update before doing anything so all packages should be the latest versions.
