Recently I made a clean install of OS X Mavericks, and right now i have setup ok mysql,phpmyadmin and apacheserver is running without problems.
PhpMyadmin as i was sure it will be, has no databases.
The databases are located in another disk installation from MountainLion that i was running before.
I understand that i can login PhpMyAdmin and export those databases in .sql one by one but there are a LOT,so i was wondering if there is a faster method to access the files and move to the Mavericks disk.
I remember in another installation i was digging around and i found those databases in the disk but my problem was that they were directories and not just .sql files to copy/paste, and i think that i had permissions problems
By that time they were not many so i prefered to use standard method, export from phpMyAdmin and then import again in the other OSX installation.
I have root access for sql.
Basically everything is the same/carbon as the old installation of MountainLion (username,password etc) so i was wondering if i can copy/paste somehow method.
If permissions needs to be set correctly please advise.
Try out MySQL Workbench for exporting and importing databases:
Workbench
Features
You can connect to one database and fetch data directly from another.
Allthough DannyThunder answer can help a lot other users (and i will choose it as correct) i will go with what most of the devs suggest, to use mysqldump. Problem was that i thought i will not have access to old sql that is why i had to copy/paste somehow the folders, i have backup allready and i am in mavericks and currently restoring.
Backup (from another OS,server etc): mysqldump -u username -p -–all-databases > file.sql
Restore (to the new OS,server) : mysql -u username -p < file.sql
The others have given several good alternatives (I tend to use mysqldump as well), but I'll just point out that phpMyAdmin has no problem exporting multiple databases. Not sure why you think you have to do them one-by-one, but from the main page click Export; by default all databases are selected, you can use the "Custom - display all possible options" radio button to select certain databases only.

First ever Stack Overflow post, thanks for your time. Any constructive criticism on how to post better, please just let me know. I have done a search on my query and have found similar posts, but I was unable to use the information within them to resolve my problem.
I have created a mysql database using the terminal window in my Ubuntu system (which I am also new to, having been a lifelong windows user). I used the following code in the terminal window:
$ mysql -u root -p
Then once in mysql, I did the following
CREATE DATABASE securities_master;
USE securities_master;
I created a user and tables in the database using some other code, that doesn't seem relevant here, so I won't bother posting. However, I then decided I would like to take a look at the tables in the database, so I downloaded an SQLite browser. It was at this point that I realized I could not find my database file.
I tried to find the answer on previous stack overflow posts, and tried the suggestions of:
locate sqlite
locate .db
locate .sqlite
locate securities_master
But unfortunately, none of these showed the file I was looking for. The only place I can think of would be what is called the 'root' directory in my computer, but the Ubuntu file manager system won't let me view it because it says I don't have permissions. Is this where it might be?
Could someone shed some light on where I might be able to find this file/database? I know it is definitely there because if I try to CREATE it again, I get the message that it can't because it already exists.
Thanks again.
sqlite and mysql are two different databases. You can't use sqlite on a mysql database. sqlite is a single-file database, in which users just open the file and read and write to it, while mysql is a more traditional relational database system with a server and a client, where the server manages the database (which is generally in a directory of files), while the client just connects to the server.
Where the mysql database is located my depend on your system, but it's usually in /var/lib/mysql. You can look in /etc/mysql/my.cnf for the configuration file, which should have a datadir option that refers to where the actual data for the database is stored.
You can check my.ini file to see where the data folder is located.
Usually there is a folder {mysqlDirectory}/data
MySQL data storage:
Commands.frm
Commands.myd
Commands.myi
The *.frm files contain the table definitions. Your *.myi files are MyISAM index files. Your *.myd files contain the table data.
as mentioned in the answer before mine, mysql and sqlite are two different systems.
You mention you used the cmd line mysql to create the database and then wanted to view the tables. If you're simply trying to see which table are created, in the same command line you used to Create the database you can run show tables;
If you're after a GUI for this, we'd need a bit more context. Is this ubuntu system a remote server, or are you using the desktop version?
You say you're a long time windows user, If you're using windows locally, I personally like SQLWorkbench for accessing my remote mysql servers.
EDIT: I just re-read your post and realised you're using local ubuntu desktop so me mentioning remote was silly, my bad! However, SQLWorkbench does have a ubuntu version at https://dev.mysql.com/downloads/workbench/
I'm doing some local wordpress development, I run everything directly from my machine (don't use MAMP or XAMPP). I'm at the place where I'm ready to take the site live - searching the internet it seems like the best way to extract the database is to use phpmyadmin. Locally, I use sequel pro to create and manage my databases. I just added phpmyadmin to my localhost and can see 2 of my databases, but not all. Does anyone know why that is? I'm sure there are other ways to accomplish what I'm trying to do (and I'm happy to hear them too) but also curious why some databases are showing up in phpmyadmin while others are not.
thanks :)
It's very likely that the user connecting through phpmyadmin just simply doesn't have the privileges to see the databases. I'm pretty sure (not 100%) that your path to 'go-live' is dump and restore from local to production and this can be achieved using mysqldump to create your backup file to permit you to copy all the local data into your live machine and restore it. I would assume that sequel pro also permits this activity through gui. If you want to do it like the DBAs do, lookup mysqldump in the MySQL documentation and work from the MySQL command line client. Good luck.
I 've re-installed mysql, uninstalled MAMP.
So currently I should only have one version of mysql.
I've done the following:
Installed phpmyadmin
Created a database
I try to import data to it, but the file is too big so I do it via the command line. But there I dont see my newly created database, furthermore I see less databases.
If I do show databases; on the command it shows:
information_schema
test
It doesnt show my newly created Database and it doesn`t show other databases that were pre-installed, these are the databases that I see on phpmyadmin:
information_schema
mysql
performance_schema
test
myBBDD->the one I just created and I was looking for to import data via command-line
It seems I have two versions of mysql, but if I stop mysql via command line, I then can't access phpmyadmin so I guess it's the same one, but for some reason I can't access the same databases.
If you could throw me a bone on this? Im completely lost.
To install mysql and phpmyadmin I've followed this tutorial
[EDIT]
I tried to delete test and it did dissapear from the command-line too, so it is the same version of MySql, so it must be a permission issue... still investigating
Thanks.
Sounds like you have MAMP's version of MySQL and a standalone MySQL. See this answer:
Access MAMP's MySQL from Terminal
Just had the same issue, in my case it turned out to be that I wasn't logging in as the correct user.
In the command line, instead of running just mysql, try running mysql -u root -p (replace "root" with whatever user you used in phpMyAdmin to set the databases up). You should then be able to type in the password. Check show databases; again.
Just noticed that user Grasshopper in a previous answers' comments was suggesting exactly this, hopefully this will help someone anyway by spelling it out.
I recently switched from using XAMPP to WAMP on my Windows 7 machine so I can do fast switching of PHP versions.
I completely uninstalled XAMPP, but first I backed up my htdocs, apache and mysql directories just in case.
After I installed WAMP and had everything up and running, I figured I could just drop some of my databases from my old XAMPP install into the "data" directory of the mysql directory in WAMP.
So that worked and the database shows up in phpMyadmin, but there are no tables. Is this a permissions thing? Like maybe I don't have the same user in the new install of mysql? Or am I missing something?
Am I allowed to just copy MySQL databases from one data folder to another or does it not work that way?
Both instances are using MySQL 5.5 (at least that's what both README files say in both MySQL directories).
THANKS
When using phpMyAdmin out of the box so to speak in WAMP, MYSQL is installed as per its default installation with the root userid setup to have NO PASSWORD.
Some people seem to think they should make one up when they see the login screen, is that what you are doing?
When you do this phpmyadmin allows you to APPEAR to login but then as you do not have root's privilages you see almost nothing on its other screens and are allowed to do nothing.
Use
username = root
password = (leave this blank)
Then set a password, there is a link on the next page it presents. AND DONT FORGET IT!!!!
This generally isn't a good idea. RiggsFolly was asking about your table type because some table types are more forgiving than others. Other possible trouble spots include file system permission problems or MySQL permission problems (as RiggsFolly asked).
I'd suggest to do an export (as an SQL file) and import that for a complete solution.
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.
