Welcome,
I'm looking for php class what allow me to backup MySQL (5.x) databases under PHP.
I test many from phpclasses but most all are written for mysql 4 and under mysql5, generate wrong code.
Class should allow me to dump my database into file.
easy restore that file.
generated file (.sql) should be compatible with phpmyadmin.
You will get better results using mysqldump as compared to phpMyAdmin's SQL Export especially when dealing with large databases and large strings of data
as #Dan mentioned, use exec() or shell_exec() to run the mysqldump command
MySQL has its own dump and import abilities. You can simply call use the mysqldump and mysql clients already installed on your server. If you want to wrap that functionality in a PHP script, build the commands as strings and use exec() or shell_exec() to run them on the system.

I have multiple tables to create in my current project (each CREATE in its own .sql file) and the order of creation is important, so I'd like one file to create them all in the proper order when I create a new database. This is not a show-stopper, just an inconvenience. In MySQL (using phpMyAdmin) I'd like a single .sql file that will execute multiple other .sql files. I'm looking for something equivalent to Oracle's ability with the "#" sign (or keyword "start"):
#create_users.sql
#create_services.sql
Does MySql/phpMyAdmin have a similar command as Oracle to do this?
The mysql client has a command source that you can put into a .sql file. It reads another .sql file that you name.
This is analogous to the command of the same name in some POSIX shell scripting languages.
You might like to read this manual page to understand other built-in commands of the MySQL client: https://dev.mysql.com/doc/refman/en/mysql-commands.html
Re your comment: You asked in your question above if MySQL/phpMyAdmin has a similar command. MySQL does.
phpMyAdmin is not a product of MySQL, it's an independent community tool, and it does not have a similar command. phpMyAdmin has an import tab, with which you can upload one .sql file at a time.
The .sql files read by phpMyAdmin don't support all the same built-in commands that the command-line mysql client supports. For example, it does not support the source command, because that would require the web application phpMyAdmin to somehow read additional files from your computer. Web applications can't do that (and it's a good thing they can't).
I just joined a project where they have been using SQLite. I am more comfortable using MySQL with PHPMyAdmin. If I install phpMyAdmin and work with that will it do any damage?
It is a php project. They have alot of code (sloppy code thats so hard to figure out) for accessing a SQLite db. I dont want to effect that but I want to add some new tables to a new db using mysql and phpmyadmin which i am yet to set up because I'm afraid it will break the code written for the SQLite db
.
Are you talking merely about installing PHPMyAdmin to manage a SQLite database? That won't work, since both use completely different API's to be accessible through PHP.
Or do you wish to swap the SQLite database with MySQL and then use PHPMyAdmin to manage the database? That'll work, as long as the project supports both SQLite and MySQL.
Is it a PHP project? Probably not - mysql_-prefixed methods only work with MySQL as far as I know, and SQLite and MySQL don't listen on the same port by default, do they?
You need to work with what is deployed. If the project is using Sqlite, then use that. Databases are not all equal. If you use something different, your code might not even run on the production databases.
first of all, if you don't want affect, create a branch on github then from work this branch ..
you can also dump all table of this sqlite database to a sql file, then import this file to your phpAdmin, will create the table, since this both manager uses sql language ... just remove some ligne of code that are not compatible with mysql on sql file that you dump data from sqlite dabtase .....
here is the code for dump a sqlite database ....
first select the database on terminal on your project director
sqlite3
./open DATABASENAME
.output YOURSQLFILENAME.sql
.dump
.quit
at this stage you already have your database in a sql file
then use php admin to import this file
if it show some error, just try to remove somecode that aren't compatible with mysql on sqlfile.
I wanna reinstall windows on my PC i wanna backup my Databases in MySQL. I have around 30 plus databases. is there an easy way to back up the content and restore it later ?
You can use mysqldump -A to do generate sql dumps for all databases.
Reference: http://dev.mysql.com/doc/refman/5.1/en/mysqldump.html
Alternatively, you can also just copy the acutal data directory.
Edit: apologies for not being specific, as others have noted this will work only ISAM. For innodb, you'll need to backup using mysqldump or another utility such as phpMyAdmin.
Use mysqldump to create a database dump of each database. You can later easily recreate the databases from these dumps by running them through mysql. This would be the most generic answer, knowing nothing more of your set-up.
If your databases contains MyISAM tables, then you could just copy the files. Otherwise (using INNODB) this doesn't work.
I assum you don't have the binary log activated, you should use mysqldump.
Take a look at: http://dev.mysql.com/doc/refman/5.1/en/backup-methods.html
You could try with PHPMyADMIN if you don't feel confortable with mysqldump.
go to phpmyadmin and export all the database.. After installing wamp in ur new pc.. go to import and import the files you've exported previously..
Have you given the GUI tools a try?
http://dev.mysql.com/downloads/gui-tools/5.0.html
Have a look at the "Backup" option in the MySQL Administrator. The "Restore" option might also be helpful after the backup is done. :-)
Allows you to backup a single db or all db's at once.
You can use SQLyog MySQL GUI to backup your database. It has scheduled backup(you can export data into a single file or as multiple files) and backup as SQL dump(The dump will contain SQL statements to create the table and/or populate the table) to take backup and can restore those .SQL files using Execute SQL script tool.
try the tool here.
I backed up my db with mysqldump from phpMyAdmin. Using MySQL 5.0.22. Made no changes to database file. Import fails. Found many instances of extra spaces using notepad, but now cannot find any other such extraneous spaces. Error is 1064.
Any suggestions on how to import file properly?
Thanks.
I encountered problems with mysql dumps of entire databases including views. So now I dump the tables and data as a separate dump, and export the views, stored routines and functions separately. I restore the tables first then the views etc.
Having come from MS SQL Server and Oracle I would like to know if there are any totally reliable tools out there for MySQL database backups and restores.
You have done several things wrong here
Using PHPMyAdmin for anything critical, especially backups. It is not production-ready, in my experience. Feel free to use it for unimportant read-only work on noncritical servers however.
Editing mysqldump files with notepad (or any other editor). Despite appearances, mysql dump files are not text files and should not be edited with any editor. They contain binary data which is not valid in most character encodings, and therefore can probably not be loaded/saved without introducing errors.
Make a fresh dump using mysqldump, which is the only reliable way of making them, and import that. Do not edit mysql dump files using notepad or any other text tool (this includes the likes of grep, sed etc).
If you need to edit a mysql dump file, then restore it into another (i.e. non-production) database instance, make the necessary changes using SQL commands and re-dump the database. This may be slow but it's reliable.
Sorry for a noob question regarding MySQL. I downloaded FlightStats to learn about mysql but I can't figure out how to register it with my localhost mysql db. I know in MS SQL you can simply register any sql db using sql studio. I tried to google but come up with no result. Perhaps, my search phrase is wrong. I'm searching with "how to register a mysql database, register a mysql database...etc.". How do you register or setup an database from existing database like FlightStats? I'm using DBVisualizer. Is there a way in dbVis that I'm not aware of to regsiter a database?
Thanks
edit: sorry for the bad wording. I found this. I have the .myd, .myi and .frm and I want to get it to restore(?) with my local mysql instance. I look at all the answers but I'm still confuse as how you restore the database from those 3 files.
A little background first. The FlightStats download page linked to in the original question appears to provide zipped tarballs of the binary table storage files from the MySQL data directory. Given that this is considered a viable means of distribution, and combined with the use of MERGE tables, I would surmise that this tarball contains a bunch of MyISAM data files (.myi, .myd). Jack's edit confirms that this is the situation.
This is an atypical means of distributing a MySQL data set, although not at all uncommon when backing up MyISAM storage, and probably not all that unheard of for moving large data sets around; it likely works out considerably more space-efficient than a corresponding dump file. Of course, in SQL Server land, it's pretty common to attach database files into an instance.
Broadly speaking, you'd recover the database as follows:
Locate the MySQL data directory; typically /var/mysql or similar
Create a new directory with the desired database name e.g. flightdata
Extract the .myi, .myd and other files from the tarball into this directory
Make sure the entire directory is owned by the user MySQL runs as (usually mysql) - use chmod -R to make sure you get everything
Open a MySQL console
USE <database-name>
SHOW TABLES
You should see some tables listed. In addition, the downloads page linked includes a couple of SQL scripts, which contain SQL commands that you need to run against your database once it's in place. These will cause the merge definitions and table indexes to be rebuilt. You can pipe these into the command-line client, e.g. mysql -u<username> -p<password> <database-name> < <sql-file>.
It may be a good idea to shut down the MySQL server while you're doing this; use e.g. /etc/init.d/mysql stop or similar, and restart once the files are extracted in place.
There's generally a way to import sql files using a GUI database tool. I'm not familiar with DBVisualizer, but as long as you have a MySQL command line client installed you can do it there as well. It's pretty easy:
Create a blank schema. You can do this in your GUI tool or on the command line client. Just use CREATE DATABASE flightstats;, or whatever name you want.
Use the following command line syntax to import/run an sql file on the new schema: mysql -u <username> -p flightstats < /path/to/file.sql
The -p option prompts for a password. I generally set up the database using step 1 as the root user, then GRANT some permissions on it to a new user id, then use that user id to run the SQL file.
This process is pretty much what a GUI tool will do in the background.
Registering a database? dont know what that means however mysql gui tools can help you creating a database. Have a look at it or better you download phpmyadmin.
Google WAMP for Windows.
Google MAMP for Mac.
Google LAMP for Linux.
Any questions?
