SO guys, we had legacy website that has a 12GB MySQL database. We decided to port the legacy website to WordPress and need to import the database into PHPmyAdmin without breaking the database and to implement this in the shortest possible time (although time is not such a critical matter if this can be done painlessly but correctly). So would appreciate if someone can guide me in the right direction and provide detailed instructions.
Thanks guys.
I dont know much but i can recommend to back up you're files befored doing any transfers. If you have a fast internet speed then you guys can try to download the SQL database as a compressed file and dump it into the wordpress new database. The database for mysql should be in your cpanel folder (since all cpanel folders/designs are different it would be best to look up "where to find the msql database on hosting company name's cpanel" and once you find it then you can transfer it whereever is possible)
This is the easiest and most correct way.
mysql -u username -p "dbname" < "path/to/bigdata.sql"
If you have FTP/SSH access, then this is the most probable way.
Upload your .sql via FTP
If you have access to CLI , just run the command above
Normally , this will be fast, but since its 12GB, it might take 30min-1hour depending on server resources.
You can also use other options like this one .
I've already experienced importing 61GB before with just this one-liner.

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 have a functional site on my local laptop that I am trying to port to a webhost. Now I was successful in doing this once which must have been a stroke of luck. When an issue forced me to wipe and rebuild, I now find myself unable to migrate the site. Now when I try I get a bunch of errors regarding missing tables.
My process was as follows:
Export mysql table;
FTP website files and sql datatable;
Import sql datatable into new sql database;
Visit the new IP address.
Was I lucky and any way I can fix it? I do not have that much content but I would like to avoid recreating it all.
Please help!
Not sure how helpful I can be without knowing what the specific error messages are.
One thing I can think of is dropping the database and recreating it. Assuming you have command-line access:
mysqladmin drop database_name
mysqladmin create database_name
And then use mysql to import the new dump file. I find this is the safest way as sometimes mysql complains about "duplicate tables" or something similar when you try to restore over the top of an existing database. I can't give any better advice without knowing what the specific errors are.
I suppose you have already done this, but also make sure you server meets the minimum Drupal requirements: https://drupal.org/requirements
I am using Workbench to export a database stored on my hoting providers server, will the server experience any downtime whilst I am exporting the data?
The only reason I ask is because when I back up my local SQL database my server needs to be switched offline for it to work.
All comments will be much appreciated.
Ben
No it will not cause a downtime, unless your server has really low resources (in which case you should find a better hosting). Seriously though, nothing bad will happen.
Also I can hardly imagine why you need to disable your localhost for backup... Workbench uses mysqldump for exports and this in turn needs MySQL to be online...
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 MAMP for Mac.
Google LAMP for Linux.
Any questions?
