  • Remote connect to mysql?

    - by chobo2
    Hi I don't use php or mysql but I am trying to upgrade a phpbb board I got but the one click installer forgot to install some stuff in the database so I can't upgrade to the newest version till I add the missing stuff. So I need to do a remote connect to mysql database but I am not sure how to do this or what software I need(free, and very easy to setup I don't want to spend much time on this). I don't really want to use phpmyadmin since I don't want to start setting up a virtual directory and whatever else it needs to be installed. Like I said I don't do php or mysql I just choose it since in my hosting package it was one click to install phpbb and I had a mysql database free. Thanks

  • Drupal install on remote mysql

    - by user1448660
    I am trying to install drupal on remote mysql server. I have created the user in mysql and granted the the privileges. I am able to connect through command line from my web server like this "mysql -u xxxx -h 10.xxx.yy.zz3 -p". But when I tried to install drupal I get "SQLSTATE[28000] [1045] Access denied for user 'xxxx'@'localhost'". I have given the privileges for "xxxx"@"10.xxx.yy.zz3" but drupal appends localhost instead of IP to user name. I have changed settings.php to mysql server IP. What am I missing?

    - by b0rman
    I trying to make MySQL available by 2 ports: 3306 and 3339 I added rule to iptables: iptables -t nat -A PREROUTING -i bond0 -p tcp --dport 3339 -j REDIRECT --to-port 3306 and everythin is great for remote connections.

  • Maximum capabilities of MySQL

    - by cdated
    How do I know when a project is just to big for MySQL and I should use something with a better reputation for scalability? Is there a max database size for MySQL before degradation of performance occurs? What factors contribute to MySQL not being a viable option compared to a commercial DBMS like Oracle or SQL Server?

  • Taking MySql backup from my Java application

    - by dhiraj
    I am developing a Java application with MySql as the database. I have to dump the MySql database from my application periodically(let say every day at 10 a.m.) and I have written a batch (.bat) file for dumping the database. The batch file is working fine, but the problem is that it is asking for password each time during its execution. Is there any way to dump MySql database without prompting for password and achieve it from Java application periodically?

  • MySQL features I can rely on being available

    - by xrstf
    So I'm developing a PHP/MySQL based CMS which requires PHP 5.1 and MySQL 5.0 (with InnoDB support) at least. I'm now wondering what features of MySQL I can safely use without noticing one day that "Oh, well, that crappy hoster has disabled feature X, damn, now I'm screwed." So my question is, which of these features can become problematic (= can be disabled, require special configuration, require user privilege): transactions and FKs in InnoDB (of course unavailable to MyISAM) table locking (MyISAM and InnoDB) stored procedures I just want to know once and for all what's the minimal feature set I can expect from MySQL.

  • syntax for MySQL INSERT with an array of columns

    - by Mike_Laird
    I'm new to PHP and MySQL query construction. I have a processor for a large form. A few fields are required, most fields are user optional. In my case, the HTML ids and the MySQL column names are identical. I've found tutorials about using arrays to convert $_POST into the fields and values for INSERT INTO, but I can't get them working - after many hours. I've stepped back to make a very simple INSERT using arrays and variables, but I'm still stumped. The following line works and INSERTs 5 items into a database with over 100 columns. The first 4 items are strings, the 5th item, monthlyRental is an integer. $query = "INSERT INTO `$table` (country, stateProvince, city3, city3Geocode, monthlyRental) VALUES ( '$country', '$stateProvince', '$city3', '$city3Geocode', '$monthlyRental')"; When I make an array for the fields and use it, as follows: $colsx = array('country,', 'stateProvince,', 'city3,', 'city3Geocode,', 'monthlyRental'); $query = "INSERT INTO `$table` ('$colsx') VALUES ( '$country', '$stateProvince', '$city3', '$city3Geocode', '$monthlyRental')"; I get a MySQL error - check the manual that corresponds to your MySQL server version for the right syntax to use near ''Array') VALUES ( 'US', 'New York', 'Fairport, Monroe County, New York', '(43.09)' at line 1. I get this error whether the array items have commas inside the single quotes or not. I've done a lot of reading and tried many combinations and I can't get it. I want to see the proper syntax on a small scale before I go back to foreach expressions to process $_POST and both the fields and values are arrays. And yes, I know I should use mysql_real_escape_string, but that is an easy later step in the foreach. Lastly, some clues about the syntax for an array of values would be helpful, particularly if it is different from the fields array. I know I need to add a null as the first array item to trigger the MySQL autoincrement id. What else? I'm pretty new, so please be specific.

  • Is MySQL caching occurring, how to fix it?

    - by rlb.usa
    I think that MySQL or ASP.NET is caching my queries. I edited my MySQL sproc to remove some parameters but it keeps saying that those parameters are missing. Here is what happens: ASP.NET app calls a MySQL stored procedure. Everything works perfect. I delete some parameters from the sproc and ASP.NET parameter list accordingly. All parameters exactly match in case and order from the new ASP.NET and MySQL sproc code Upon execution, it fails, saying : System.ArgumentException: Parameter 'deleted_parameter_foo_bar' not found in the collection. at MySql.Data.MySqlClient.MySqlParameterCollection ... I delete the sproc from the database, restart my browser, and reexecute the ASP.NET page. It says the same error, that the parameter is missing - but the sproc itself doesn't exist anymore. ( I know 100% that I am editing/deleting from the right database. ) How do I fix this or make it work again; I want it to use my new sproc instead of the old one ? _o

  • MySQL replication Slave_IO_Running: No

    - by Christy
    Hi all, I have two servers that I am trying to get replication of one database between. I found a setup guide on sourceforge that I followed and I have tried various other settings since then, but no matter what I do, when I start the slave, the 'Slave_IO_Running' setting is always No.... I have no idea why or what to look at, any suggestions are appreciated. The slave setup was: CHANGE MASTER TO MASTER_HOST='myserver.mydomain.net', MASTER_USER='slave_user', 'MASTER_PASSWORD='mypassword', 'MASTER_LOG_FILE='mysql-bin.000011', MASTER_LOG_POS=1368363 (last data from today, trying to do setup again. I deleted and recreated the database on the slave from a new dump and tried to redo the setup.) I have slave_user setup for %, localhost, and the specific IP of the slave computer but nothing seems to be working... Thanks in advance for any advice or suggestions

  • amazon dynamoDB or MySQL for storing large arrays inside each row

    - by Logan Besecker
    I am trying to decide which database I should use for an application I'm making. I was leaning toward dynamoDB because of its scalability, but then I read in the documentation which said: there is a limit of 64 KB on the item size although it looks like MySQL has a similar restriction documented here This application will be storing a lot of data in two arrays, which could contain upwards of 10,000-100,000 strings in each. I estimate that these strings will each be somewhere around 20 characters long, so each element of the array will be around 40bytes and each array could be around 4MB. Given this predicament, what database on amazon AWS would you use; or how would you get around the limit of size per row? Thanks in advance, Logan Besecker

  • slow query logging in mysql server

    - by Vinayak Mahadevan
    Hi I have installed MySQL Community Edition 5.1.41 on a windows 2000 server. In my.ini file I have enabled slow query logging and have redirected the output to a table.I have set the long_query_time to 10 seconds. Then after running some queries I checked up the slow query log table and found that all the queries which were executed have been logged and a file called database-slow.log has also been created in the data folder. Can anybody please tell me where I am going wrong. I am using the inbuilt innodb and not activated the innodb plugin. Thanks

  • Django Dying on Shared Hosting Environment (Too Many MySQL Connections)

    - by Tom
    I've had a Django site up and running on HostGator (client requirement), following these instructions, for a few weeks now. I had seen two error emails about pages dying with (1040: Too many MySQL connections) but had never been able to recreate the problem. As of today, the site is completely unresponsive and all pages, even the static files, are dying with that error. Two questions: What can I do to fix this (other than caching more stuff)? Why would static files be dying like that? I can request them directly without a problem, so how are they getting run through Django? The shared hosting setup doesn't allow for a <Location> block, but there's a flag in the rewrite rule that says only requests for files that don't exist in the filesystem should be processed. All of my static files exist on the system, though they are symbolically linked files if it matters.

  • Forwarding MySQL connection with iptables and differents network interfaces

    - by Emilio Nicolás
    I have a PC with Ubuntu as a router. It has a 3G connection with a public IP to the Internet, and there is a private wireless subnet. So it has two active interfaces: ppp0: public IP (WAN) wlan0: private IP (LAN) With iptables I wannt to forward every MySQL connection (port 3306) to a local machine (10.42.43.10) of the subnet. I type these iptables commands: iptables -A PREROUTING -t nat -i ppp0 -p tcp --dport 3306 -j DNAT --to 10.42.43.10:3306 iptables -A FORWARD -p tcp -i ppp0 -o wlan0 -d 10.42.43.10 --dport 3306 -j ACCEPT But it doesn't work. telnet publicip 3306 fails :-( Any help will be appreciated. Thanks!

  • MySQL dump, output each table row on a new line whilst using --extended-insert

    - by soopadoubled
    I'm having an issue, where for ease of use, I'd like to be able to format a command line MySQL dump so that each row of a given table is on a new line when using the --extended-insert option. Usually when using --extended-insert, every row of a given table is outputted on one line, and as far as I am aware there's no way to change this, other than post-processing the dump with perl or such like. The format I'm looking for is: -- -- Dumping data for table `ww_tbCountry` -- INSERT INTO `ww_tbCountry` (`iCountryId_PK`, `vCountryName`, `vShortName`, `iSortFlag`, `fTax`, `vCountryCode`, `vSageTaxCode`) VALUES (22, 'Albania', 'AL', 1, 0.00, '8', 'T9'), (33, 'Austria', 'AT', 1, 15.00, '40', 'T9'), (40, 'Belarus', 'BY', 1, 0.00, '112', 'T9'), (41, 'Belgium', 'BE', 1, 15.00, '56', 'T9'), (51, 'Bulgaria', 'BG', 1, 15.00, '100', 'T9' However, when I dump a database using Phpmyadmin, using --extended-insert, each row is dumped on a new line (as shown by the example above). I've gone through Phpmyadmin and can't find any documentation that would explain this. Is anyone able to shed any light on this? Thanks in advance, Ian
