I need to Query an online SQL database from an iPhone app. I have been researching and have not been able to find a way to use SQL to directly query my non-local online database from my iOS app.
Is there any way to do this?
Or do you need a web service, restful api using json?
If so, can you lead me in the right direction on creating a web service (or resources that handle that for you)?
I have be trying the same thing and I endet up doing it via a MySQL DataBase on a 1&1 web domain, to Query the DataBase I made a PHP program, using (like you said) JSON to be read by the app. I dont know if that is what you meant if not maybe specifie pls. XD

I 've been thinking about a project for a Website and an iOS app. I have some domains (Webserver) with SQl. It should become sth. like a News-Blog about a special topic.
So I want to ask, if it would be possible to upload an article into SQl and load it to my app and website.
The problem is, that i've never worked with Sql before and have absolutely no knowledge about Sql. The app would be made in Swift and the Blog(Website) with Wordpress.
So, how should I proceed and where do I have to pay attention?
(Sry for my english, but i hope you understood what I want to do)
SQl = MySQL version 5.5.49
you can load data in ios app using REST API.
when you are done with you SQL integration with Wordpress you can use wordpress Web Services plugin for iOS app.
plugin http://v2.wp-api.org/
In iOS app you can use Alamofire Web API Framework to handle Web API request. https://github.com/Alamofire/Alamofire
I don't know if I clearly understood your question but I think that your main concern is to know whether it is possible or not to use a single database to store the data from BOTH your mobile app AND your website.
The answer is yes. The database will be the same, the data is simply displayed in two different views (website or mobile app).
Note that SQL will only be used to get or to add some data in the database.
Wordpress uses SQL to store data, and you can use SQL while you develop your mobile app to store or to get data from the database created by Wordpress.
SQL is the language and MySQL is the DBMS (DataBase Management System), these are two different things, as I think that you are confused about this.
I am planning to build an iOS app with using DB(Ms-Sql).
However, people recommends not to access DB from Xcode.
They recommend me to use php or asp for accessing db through a webpage.
I want to know the reason.
Also I am going to use DB only for (view) select line (not insert, update nor delete).
so is it possible to access directly to db for viewing purpose only?
thank you
It's generally bad for an application (mobile, web, any client) to directly have access to any database for security issues. Clients really should not be accessing the database, which is often holding very private/secure data. It opens up vulnerabilities (i.e., sql injection attack).
A set of web services written in php or java or some back-end technology is a more secure, scalable system. These web services can connect to the database and retrieve data. Your iOS application can call the web services and receive the data..for example in the form of XML or JSON.
I have a Heroku app with a PostgreSQL DB. Now I want to have a seperate process, possibly on a different machine, to access the DB. The suggestion on the Herkou site is actually what I wanted to do myself:
No, connecting to your database from machines outside of Heroku is not supported.
We recommend that you encapsulate data access in an API to manipulate it.
But I'm not sure how that's done best. I'd like to be able to send some JSON to the API and get back JSON as a result of that request. Like "give me all posts that are expired for a bunch of given userIds" or "update all users to be suspended if their posts contain any of the given words" in an example micropost app.
What's the best way to achieve that? Can I write an extra ruby program that is accessible via TCP and accepts JSON input? Is that even possible with Heroku? Or do I have to integrate the API into my rails app somehow? How?
Thankful for any ideas,
Tom
You will have to integrate the API to your rails app, there are many solutions for this, one of them is using a tool specialized for API building like Grape and mount it with your Rails app. This way you could have your Rails app running and also the API, both sharing the same codebase.
I am writing an iOS application that needs to access data from an external SQL Server 2005 database. I already have a website that accesses the same data.
I usually access the SQL server database using .NET along with stored procedures for security reasons.
I need to populate an array that will itself populate another TableViewController.
As I'm fairly new to the whole iOS thing, kindly let me know how I can do this. If it's possible, please suggest the syntax or Google keywords for this.
I'd recommend making a simple WCF .NET REST Service that queries your database and returns what you need.
I'm pretty sure your iOS app will not be able to connect to it directly.

The code project tutorial is very easy to follow. And you can download the project code.
It sounds like you will want to make an API to access your database and you can access it through web requests. Essentially you will be performing web requests and respond from your site in json or xml where within your iOS client side code you can parse that and do what you need with it.
I need to populate a table in an iOS application with data from a Web database
I already have a MySQL database set up but reading about this it seems there must be an easier way for the iOS to interact with a web database
Any help or pointers would be appreciated,
Thanks
You should make an API interface.
Then use the API to communicate with the database. Using the database directly is a very bad thing to do.
If you are really desperate, consider using the MySQL C library. This article explains it in great detail:
http://www.karlkraft.com/index.php/2010/09/17/mysql-for-iphone-and-osx/
For my application, I chose to create a web service to act as an intermediary between my application and the database.
This layout has several advantages. Considering you have MySQL database you can try to create some php scripts (I chose php because the API to work with mysql is very very simple and as you said, you don't need very high security or performance).
You can use these scripts through HTTP requests (you can use NSURLConnection to do these).. These scripts connect to mysql , fetch the data you need to pass the result back to the application in an easier to use format (e.g. I use JSON).
