I am connection to a LAMP Server trough PuTTY.
I have no idea if there is a GUI available so I'm doing this trough the CLI. The problem now is that I need certain fields from the database and I have no idea how the database looks since the lack of documentation.
How should I approach this. In the database there are 148 tables. Should I just go trough every table one at a time? Is there a smart way?
Thanks.
You could always install PHPMyAdmin, but if you don't have access to do so, you can try MySQL Workbench. This installs on your computer, and you just put in your server info and connect
There's plenty of GUI tools available for MySQL, some that you normally install on the server and others that you run on your desktop, here's a short list:
MySQL Workbench - Official mysql gui tool with really nice features (especially coming to db design)
PHPMyAdmin - web based interface, can be installed on the server and reached through a web interface.
HeidiSQL (free, windows) - desktop app
SQLYog (lot's of features, costs money) - desktop app
Sequel Pro (free, slim and good for macosx) - desktop app
You can also use the mysql-query browser for connect database.

My company has two web based project. Our main project (Starbooks) was built using xampp server and Codeigniter framework that installed in our Windows OS and the second project (Frontlearners) was built in Lamp server and moodle (LMS) framework with Postgres database that installed in ubuntu platform.
My goal is to collide this two projects into one by moving the second project (Frontlearners) into the main project (Starbooks) server which uses with xampp server windows platform.
My first attempt is to export the moodle Postgres database using PGAdmin then move the moodle project to the main project server on windows. But I don't know if this is the correct way or not because Postgres and mysql are different database type. I've searching across the internet hoping for the answer or tutorial related to my problem but the results are always fresh installation of moodle which is not related to my problem.
Anybody knows how to solve this problem, a tutorial link, or any article about this situation?
There is a database transfer tool in Moodle.
https://docs.moodle.org/311/en/Database_transfer
So you can convert the PostgreSQL database to MariaDB
First ensure MariaDB is installed on Ubuntu
Turn off cron and put the site in maintenance mode
Then go to Site administration > Development > Experimental > Database migration to convert the database.
Or direct to /admin/tool/dbtransfer/index.php
The tool will check the database structure matches the structures in the install.xml files. If there are any differences, then you will need to update the relevant install.xml file or database table before continuing.
If its a large database, then the UI will probably time out. So use the command line version instead:
php admin/tool/dbtransfer/cli/migrate.php --help
Having said all that, IMHO I would transfer the Windows project to Linux.
I'm practicing learning MySQL code with SQL Fiddle, it worked sometimes but now I get errors all the time when I use the "Build schema" or "Run SQL" functions.
After a while, the error printed is "Unable to get host connection: Connections could not be acquired from the underlying database!"
Anyone know how to solve the problem? Is there another tool I can use to do practice with queries to my schema?
Install your MariaDB or MySQL database server on your local machine. Install a decent native SQL client program. HeidiSQL is great on Windows. There are plenty for Mac. Any modern laptop computer (since about 2014) can handle a student- or developer- scale database server and client without breaking a sweat.
You can install phpmyadmin. But that's a php web app, so you also have to install a web server and php to get it working. Hence the suggestions for XAMPP or LAMP stack packages. I prefer the native clients; less to go wrong; less stuff in your laptop.
It's best to reserve the database fiddles for sharing SQL demos with other people. Like for Stack Overflow posts.
I am trying to design a database application for my small business. I've created a number of form driven MS Access databases for use before but would like to create a permanent solution in something more advanced & common.
I was thinking of using mySQL for the database and would then program a C# or VB application to be used in Windows. I do not want or need a web based version at this time but the migration to VB.net in the far future may be something I'll look into.
I know I can use a MS Access backend for my windows application without having to install MS Office on any or all the computers the program will be run for.
But here is my question. Is it necessary to install mySQL Server on the PC hosting the database, on all the PCs accessing the database or can I just use the database file as the backend and Visual Studio will have all the necessary tools I need to access it?
If I have to install the server I may just stick with the MS Access database as the needs for an excessive amount of database storage won't ever be an issue.
You'd need to install MySQL server on the Server hosting the database. The clients would then connect via the network. You will however need a driver to access the MySQL-Server with VB.NET on the client machines. A simple DLL-File might be enough, though.
If you are looking for a file-based database solution have a look at SQLite. But you will have to watch out for concurrency issues here.
I would like to have a Flash Application (not air) to connect to a local database.
Air is not only getting unsupported by Adobe in LINUX but besides, it has serious problems and miss implementation with SQLite.
So we want to connect to a local MySQL database.
This application should be simple, so we do not want to also have an unnecessary web server (also local) to make a middle communication between the flash app and the MySQL server.
There is this driver that allow to communicate Flash with MySQL
http://code.google.com/p/assql/
Question is:
Is this the best approach?
Would it be any problem using this approach when installing the whole application to each client? (because we also in the installation should install a MySQL server).
A MySQL SERVER is called a SERVER for a reason: It is meant to be installed on servers, not on clients. So the answer to your question is:
1) No, this is not the best approach. Not even close. You would be better off using a SQLite database (however shitty you may think it is)
2) Yes. Nobody would like installing a MySQL server on their computers just for the sake of running your application. Think of casual (non-expert) users who would need to install and configure the server just for running your app. That is the very REASON why they developed SQLite and so many languages support it.
You should check out http://code.google.com/p/air-sqlite/ for sqlite access in AIR (I don't know if this is the same as the inbuilt code or not, so just check that out)
Is there a way to view database information via a web application. Since I don't want to install mysql client on my machine.
Via a web application, you can install phpMyAdmin.
Otherwise, if you can install something on your machine there are tools that work for any DB, like DbVisualizer or the MySQL specific MySQL Query Browser part of MySQL GUI Tools.
