I have created basic CURD application using Play framework. It is working perfectly fine in my current machine. When I am trying to run the same application from my friend machine it is working but it is unable to store data into Database. It is just storing null values in Database.
I have followed same configuration in same Machine and I have used MySql as my Database.

I am creating an android application in android studio and I am using SQLite as the local database. I am using MySQL database as the application server. I want to be able to pull the data from MySQL into Android Studio to access it and also sync the local SQLite database and the MySQL database.
I do not want to use Web services and php files to connect MySQL, I would like to use JDBC instead, so My question is:
can I use JDBC to this purpose and how?
I am not much familiar about this but have some queries.
I have installed MySQL database in a desktop and using it for creating a web application in my workplace. After the app gets created, I want all the computers to have an access to the database in the desktop I have used as it has all the DB tables.
One more thing I want to know that as the application needs application server to run it, is there any way I can achieve it in this scenario.
Thanks.
To be specific
I have a local server running on my pc called MySQLServer57
and I'm running it on MySQL Workbench
i want to know: What tutorials can i follow or find that will show me how to extract information from the database like tables, values etc and use them and display them on the web app coded in c#. etc :)
I have successfully created a ASP.NET MVC 4 Web application and now I want to deploy it on a test environment. The target server is not an Azure server, but it is a Windows Server 2008 R2 Server with IIS installed in it.
Now I have published my solution using Visual Studio 2013 Professional, everything works fine excepts the Database. It's a Mysql Database that works perfectly with Entity Framework 5 (I have added the Mysql provider, mysql.data.entity.dll , mysql.data.dll on my web project and all the configuration to make it run locally). Once I publish the project, it is deployed on IIS but it doesn't retrieve data from my Mysql Database. I want to notice also that in the Publish wizard, although I specified the connection string, it says that
there is no Database detected
It should display the name of my context instead of that. Would you please help me know why the publishing wizard doesn't recognize my Mysql Database? thank you for your help !
I was able to use Asp.net MVC with MySql using Entity Framework code first, like the one explained here http://www.asp.net/identity/overview/getting-started/aspnet-identity-using-mysql-storage-with-an-entityframework-mysql-provider ... Here a couple the things I notice:
The generated migration contains the schema dbo. that won't work on MySql so I went to the migration file and remove all schema references. (there are better solutions, like configuration/setup wise)
The unique key length problem, such as UserName (defined in the asp.net Identity) has a maximum length of 256 and that is over the limitations of mysql unique field, so I changed the length to 128. that solved this error
Specified key was too long; max key length is 767 bytes
I did have some troubles using the publishing wizard, since didn't show me any of my MySql Drivers to test my connection to my db, so I just change the Connection string in the config file and apply my migration changes to the new/testing DB from the Package Manager Console > Update-Database (this could be your temporary solution until you find a automatized solution)
I am thinking about developing an application to store a movie database, allowing the user to store information about which movies it owns, which movies it wants to see, etc.
I was thinking of developing this application with the Qt framework and using MySQL to to the database part.
However, I have a few questions. When deploying my application on other machines, won't I need MySQL installed there too? Or will the .dll suffice?
Can I connect to a database that does not exist, on a machine that does not have MySQL installed?
