I have been searching this topic for a long time but I haven't found the answer I wanted. I want to connect to a MySQL database on a client-server and insert some info on a table using an app I made using PhoneGap. I found things like that but didn't seem to do what I want them to do: http://docs.phonegap.com/en/2.7.0/cordova_storage_storage.md.html#SQLTransaction
This documentation page doesn't make any sense to me.
Does anyone know how can I solve my problem? Thanks in advance.
You normally don't access database on your server dirrectly from the app in your phone.
The doc you saw about SQLTransaction is about writing data to the SQLite database that is inside your device, not to write to a remote database.
What is usually done to communicate with a remote database is we perform http requests to a web server (php, java, .net, ruby, perl or whatever you like) and that server will communicate with the database server.
If you really want to communicate with your mysql server from your phonegap app, you would have to include native mysql libraries in your project and write native code to communicate with the mysql server. And I don't think it woule work very well through a data connection...

I want to develop a desktop application (with VB) and connect it to an online database (MySQL), I already had my hosting site and I thought why not create a MySQL database in my domain (which by the way is offered in the pack) and connect my desktop application to this database.
Why an online database? Because I want to develop a mobile application to keep me informed of any changes in my business without moving to my office.
The problem is that my VB6 application cannot connect to my MySQL due to domain restrictions. I wondered how these thousands of apps work with online data? What are their magic solutions? Or did I miss something?
Please any idea? I worked with VB6 and a local database which is no longer productive.
You can create a simple PHP file on your server that will take the data from your VB6 apps and store it in your database. You can also create a simple PHP file that will query your database and return the results in a format that your app can read. This is the typical way that a VB6 app will interact with a server-side database.
I am just starting to use Electron and I have a question about databases. Due to the kind of App I am developing I need a relational DB.
The idea is the user will open the App, if there is connection it would store the data both locally and remotely. If the App is offline it will store the data locally and whenever is online again it will send that data to the remote server. Basically it will be thee same database (local and remote) but it can work offline if necessary.
I am lost on which database will be better for this. As I said I am using MySQL right now and I know you can use MySQL with nodejs so I might give it a try. Also, I am used to use MySQL within a backend language such as PHP, how would you do it in Electron?
Thanks for your time guys!
I have a XAMPP web server running as well as MySQL running. I have a website that interacts with my database, but I was wondering how I would go about interacting with my database with HTTP requests, in my case through Lua. Any examples or tutorials you point me to would be great, thanks.
I am developing a desktop app and I want to store data in hosted database like MySQL/MongoDB. I know one solution is using webservice to manipulate db. I am wondering is there a way to connect desktop app with hosted db directly.
I am using OpenShift I know I can use port-forward to do this. But it's unpractical to open port forward every time for every PC. So is a way simply like this:
mongoose.connect('mongodb://user:pass#host:port/db');
I tried this but I got 'connect refused' or 'connect not found' errors. OpenShift doesn't allow external access to database directly because security issues, right? Then how could I do it without port-forward?
Also I read some articles about SSH, is it possible to use SSH to access db directly when desktop app is launched?
Thanks for any suggestion.
I don't think OpenShift is going to be a good fit for what you are trying to do, unless you decide to build a service layer between your desktop app and the database. It sounds like you are looking for a Database As A Service. You mentioned both MongoDB and MySQL. MongoLab is a good MongoDB DBaaS option. For other databases like MySQL, PostgreSQL and several others you could look at Amazon RDS.
I'm currently doing a iOS application for school to connect to school mysql database.
It should be able to connect to it through the tools on xamarin studio.
I tried a lot of different coding to connect the database, but was unable to do so.
Is there any tutorial or example code to let me learn on how to do it ?
Thanks for any help!
Do not connect directly to a database from a mobile app. Doing this requires exposing your database server directly to the web, which is a horrible security risk. The better approach is to use a web services layer to broker the interaction between your client and your server.
http://docs.xamarin.com/guides/cross-platform/application_fundamentals/web_services/
While people are right and the best way to connect to a database is to use a web service there are some times you want to connect directly and ways to make the connection more secure (ip restrictions on the mysql server).
Here is a plugin with code examples on how to do it:

Be sure to pay attention to the first forum question on errors and how to resolve. You need to include a reference to system.data, I18N, I18N.West in your project and also make a call to the constructor for I18N somewhere in your code.
new I18N.West.CP1250();
