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

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)

I am trying to connect to AWS Athena via my Windows as well as Mac system. My goal is to have a SQL Editor that I can use to perform quick research about the data. I was trying to find tools and tutorials for connecting to Athena. So far I have only found some tutorials around SQL Workbench. What are some other tools that you guys leverage and is there something particular that you like about that tool and how easy was it to setup either on Windows/Mac.
I use SQuirreL SQL for connecting to Athena. It has served the purpose so far. Once you import the JDBC drivers(you can download them from AWS's site) the tool itself is pretty straight forward to setup. The URL that you can use to connect can be seen here -
jdbc:awsathena://AwsRegion=<AWS Region>;User=<AWS Access Key>;Password=<AWS Secret Key>;S3OutputLocation=<S3 folder>
I'm pasting the "Overview" of SQuirreL below:
SQuirreL SQL Client is a graphical Java program that will allow you to
view the structure of a JDBC compliant database, browse the data in
tables, issue SQL commands etc, see Introduction. The minimum version
of Java supported is 1.6.x as of SQuirreL version 3.0. See the Old
Versions page for versions of SQuirreL that will work with older
versions of Java.
SQuirreL's functionality can be extended through the use of plugins.
A short introduction can be found here. To see the change history
(including changes not yet released) click here.
For a more detailed introduction see the English or German of our
paper on SQuirreL.
Susan Cline graciously took the time to document the steps she
followed to setup an Apache Derby database from scratch and use the
SQuirreL SQL Client to explore it.
Quite some time ago Kulvir Singh Bhogal wrote a great tutorial on
SQuirreL and published it at the IBM developerWorks site. He has
kindly allowed us to mirror it locally. The tutorial is not really up
to date but especially for doing the first steps it is still of help.
SQuirrel was originally released under the GNU General Public License.
Since version 1.1beta2 it has been released under the GNU Lesser
General Public License.
Another tool that I have used pretty extensively is SQL Workbench. This is also sort of recommended on the AWS site. The is good, but I found that it would hang up sometimes and I would loose my work.
Both of these can be easily downloaded from the links provided or if you like to use CLI then Homebrew can be used on MacBook or Chocolatey on windows
Some other tools that you can use are DataGrip by JetBrains. Guide to setup the tool can be seen here. The functionality of DataGrip is also built into IntelliJ Ultimate Edition.
DB Visualizer is another tool that can be used to connect to AWS Athena the guide to connect can be found here
TeamSQL and Razor SQL are some other tools that you can leverage.
One of the strengths of JDBC drivers is that as long as a tool supports JDBC, you can use it for any data source which has a JDBC driver. First, get the JAR file for the JDBC driver for Athena here: Amazon Athena Connect with JDBC. Java works across platforms, so as long as you have Java in your Windows/Mac environment, you should have no problem using any of these tools.
The tool SQL Workbench/J is fairly popular, but I find it frustrating to work with when switching between multiple databases.
Another tool is Squirrel SQL, which also supports JDBC drivers. I prefer it, but it looks a little less pretty than SQL Workbench/J. Once you've downloaded the JDBC driver, configure it in SquirrelSQL by going to Drivers and then adding a new one. Label it "Amazon Athena" and specify the Example URL as jdbc:awsathena://AwsRegion=[Region];User=
[AccessKey];Password=[SecretKey];S3OutputLocation=[Output];
[Property1]=[Value1];[Property2]=[Value2];...
Leave the Website URL Blank, but specify the Class Name as com.simba.athena.jdbc.Driver. Add the .jar file of the JDBC driver to the "Extra Class Path" page.
Once you've set up the driver, you can set up connections by going to the Alias tab and hitting the plus sign. Simply fill in the values in the example URL to point to your data source. Once you're connected, you're good to start writing queries.
SquirrelSQL saves the connection information for you, allowing you to quickly jump between data sources, and makes it easy to write multiple queries in one input window, with their outputs going to separate tabs in the output pane. I've used it for database, exploration, DDL, and regular day-to-day tasks with data. It's been good for most anything I've connected it to. It is definitely not perfect, but it's getting better all the time.
I guess you need a Docker SQL Editor that you can use to perform quick research about the data.
But I suggest two ways.
One is Offline/Online and with installation methods, which you can use with a fixed connection.
The first solution is to select a system as a server and connect to it from other operating systems. This is the traditional / old solution.
In the second solution you just need to be trained to work with Docker. This is a newer and more popular solution.
if you want use MySQL in MAC read this article :

But you need a synchronous space for use MySQL or other DBMS you can use docker.
Docker is very Flexible . But you need connect to internet.

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 have a Winforms desktop app that need to read/write data from/to a MYSQL database. The MYSQL server is on a machine that runs on Linux OS. I need to know if a .NET connector is to be used or an ODBC connector?
Also, considering that I do not need remote access to MYSQL server, is a connector sufficient to access the server from the windows desktop? Do I need to do something on the server side? I've been looking around and getting mixed signals, some people said a web service is required while others said no.
I need to know if a .NET connector is to be used or an ODBC connector?
I never connected to MYSQL before, but i think you can use these data provider or, ODBC too.
Is a connector sufficient to access the server from the windows desktop?
Yes. A valid address to your server is all you need to access it, using data providers or ODBC. Of course, your database need to be up and running too.
Do I need to do something on the server side?
Just install your MYSQL database.
Maybe this link will help you.
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.

Is there any way to use MySQL without install? I am making an desktop application using Visual Studio and C# that uses MySQL. I will use this program on another computer.if this computer has no MySQL installation my program will also work? Can I move my database with my application?
No, you do not need the server installed locally. You do need some sort of client, though. For C, you would need the mysqlclient library. I assume C# has something similar to enable the CLR to talk to MySQL.
If you are looking for a portable database, check out SQLite. As for the best library for C#, see these answers:
What is the best way to connect and use a sqlite database from C#
Is there a .NET/C# wrapper for SQLite?
No... You will need the computer to have mysql and your compiled code. What you CUD do if your database is not too big is hardcode the data storage and retrieval in your code itself.. in that case you wont need mysql installed there..
OR you cud allow network access to mysql on another machine(server) in that case u only need mysql on the server
