Does anyone have any introductory level walkthrough on how to set up a parse live-query? Do I just grab the latest version on github and it should have everything pre-set? I'm not sure where to start.
there are many answers out there regarding the same question. However, i am just gonna give a brief how-to here.
Firstly, you can use download the parse server from this github.
In the index.js, if you read through it you should find something like
liveQuery: {
classNames: ["Posts", "Comments"] // List of classes to support for query subscriptions
}
the classnames "Posts" and "Comments" are basically your database table names. I believe you are using mongoDB for your database right?
After which, once you upload the parse server to AWS/heroku, you should be ready to use live query.
On the client side, you just need to subscribe to table names you did at your server side and you are good to go.

WSO2 Identity Server 5.0.0
I am wondering what the full path of SQL queries would be if i wanted to create and update Service providers via SQL queries. It's more than adding to the SP_APP table as a newly inserted entry by that means doesn't show in the UI. I was looking through the identity-core code and got a little lost, since it seems to abstract out some intricate registry stuff.
Anyway, I'd love to know how I could navigate the database to look at stuff by these means.
I would suggest moving your WSO2 IS completely onto SQL Server. You can then see all the tables and scripts that are run against it (using something like QueryProfiler). To do this, follow the instructions: https://docs.wso2.com/display/ML111/Setting+up+Microsoft+SQL.
Note that at the end of the document you must run two scripts (not just the one they show):
<PRODUCT_HOME>/dbscripts/mssql.sql
<PRODUCT_HOME>/dbscripts/identity/mssql.sql
I have to admit that the documentation on WSO2 IS is not very good or complete, but they have been good at answering questions. SQL Server was hard to set up as some of the steps were old (as you see they reference SQL Server 2005), but if you know your way around SQL Server pretty well, you can figure out the minor things. The largest issue was the second .sql script that needed to be run.
That should set you up well enough to see what is being called when set up Service Providers, or anything else that goes into the database.
I am looking to have my data in JSON format from SQL server database.Is there any API available for it ? Basically I need it for demo purposes only.
Some thing like this Looks relevant but again I am not sure how is that being used here. I have apache installed.
Can I get some directions on it or may be some other API relatively easier to use ?
A Web API might be a good choice. I recommend using the Database First approach if you already had the Database: http://www.asp.net/web-api/overview/data/using-web-api-with-entity-framework/part-1.
Well, a better tutorial can be found here: http://tomislavbabicnet.blogspot.com/2013/03/build-application-using-aspnet-mvc-4.html
You can try doing it in the sqlserver.
Go through this link. It will solve the purpose.
After I've done developing my web site using Hibernate and Struts2, now I want to put it on Cloudbees hoster, the problem is that I don't know how to create my data base's tables?!!
I used the method shown in this video to create my tables: http://vimeo.com/33445098 But it doesn't work!!
It shows how to connect to my server by using MySQL WorkBench, when I created new Server instance the connection couldn't be established, although I used the appropriate informations.
Thank very much :)
After days of looking around on the web I found this, it's very useful

I am trying to develop a BlackBerry application that will show data from an SQL Database from a server. I was researching the new HTML 5 option for blackberry (WebWorks) and noticed that it apparently cannot connect to any server data by itself. Some links state that I would need javascript coding to obtain it. I looked into the option of PhoneGap (link here: http://phonegap.com/) and decided I'd try using HTML 5 to produce the application. I have never touched SQL databases before and I am wondering how I would connect the two; meaning how do you pull data from the server given that you are working with HTML5?
I have looked at:
Where is data stored when using an HTML 5 Web SQL Database
Process for pulling data from a sql database
among others but I am still unsure as to what to do. I would be looking to "view" the data from the server and display it on the app. It would be something of the sort:
- HomeScreen: What data would you like to view?:
- Dropdown list of categories (from the database)
- Selecting Entry in dropdown leads to available information (from the database)
Any help would be appreciated, and of course thanks in advance.
the new (and pretty awesome) features of HTML5 is happening in the browser on the client side. What you will need is a back-end on the server side doing some magic. It is true that browsers now have databases but these are located on the phone, computer etc and as I understand your question you want these data to communicate with data on your server. To move data across the web you will need to perform HTTP-requests which can easily be done through javascript and ajax. Look a bit into these technologies and make a little server-side script that gathers data from the database and send it in a structured format to the phone (JSON, XML), then make a script in javascript on the client-side that parse these data and utilise them.
Good luck!
I am building an android app and I have an SQL database stored on a server. I need to either pull the database into android or query the database and have it return information from the tables. I have searched all over the internet but I haven't found anything that explains how to connect to the server from android. How can I do this?
You can't query database in a server from android directly. You have to write PHP scripts to query database from server. You have to keep the php scripts in a web server. And from android application you have to get the data from the php page.
I don't think there is a reasonably simple way to 'pull' the database or connect to it using some soft of ODBC connection. And I don't think it would be wise to use it even if possible.
I believe the best way to solve your problem would be to implement some sort of REST API interface to your database and fetch data as needed.
actually, despite gypsicoder's answer and several "how to"s on the internet, there is a way to connect/query an SQL database from android
you just have to download the corresponding JDCB. for mysql: http://dev.mysql.com/usingmysql/java/
then you just use the java.sql interfaces/classes to do stuff (mysql has a reference manual at above link)
