Is there a way I can convert my MDF database to a CSV for supported webhost? If so could anyone enlighten me on how?
Open the MDF file in SQL server as it was intended then run and export a query from each table. You will have one CSV for each table.
I have no clue what you mean by "for supported webhost". Please put more effort into your question if you want someone to spend time answering it.

I hope to get a solution here. I am completely new to R and really all i need it for is to extract data from power query and append it to an existing csv file. The only export approach that i have come across only works for exporting to the local c drive as per my example below. This approach however does not work for files in sharepoint with a URL. Can you please advise on a solution? Thanks
write.csv(dataset,"c:\\documents\\test.csv ,append=true")
I have an app that saves your data and retrieves your data under a ID number of your choice! The only thing is I have people asking for an excel document of all there saved data! Does anyone know how I would go ahead with this! I am using Swift and Xcode 6.1! I am also using a SQLite file that core data has made for me.
Thanks,

Creating native Excel is likely a PITA. You should export to CSV, though the format seems to be another PITA for one is liking comma, the other semicolon and the third tabs :-(
I have a huge dataset value in JRDatasource object and am not able to export it to Excel as it will give me memory out of space error. So am planning to split the JRDatasource object and export the data part by part. Any idea or suggestion on how to implement this? Or any other way suggested also fine for me. Thanks in advance.
I dont know much about JRDataSource, but I'll offer another solution.
Take a look at Apache POI library which enables you to create excel files on-the-fly.
So you can read from the data source element by element and persist them on a excel file.
About 3 years ago, I was looking for a way to allow a web app user to download table results to an Excel file. I knew that I didn't want to put Office on the web server and that I probably wanted to create the XLS file in XML format. The question was: what was the best way?
Now I am writing my resume and I am trying to recap the things that I did and I am concerned that I didn't take the best approach and I am wondering if somebody can tell me whether my suspicions are true.
Basically, I saved an Excel file as XML and then looked at the contents of the saved file and reverse engineered what I thought was a pretty cool SDK to create an Excel file in XML format. It was fairly robust with options , nice object model, etc.
But did such a library already exist? One that I could have used? I want to know if I will need to defend this "accomplishment"
Also, could anyone recommend me a good place where I can see actual resumes of people with .NET / SQL Server or general developer skills?
You can try SmartXLS (for Java or .Net), it supports most features of Excel (cell formatting, Charts, formulas, pivot tables etc), and can read/write both the Excel97-2003 xls format and the Excel2007 openxml format.
These people wrote a perfectly good one that you probably couldn't implement yourself for as cheaply.

Is it possible to import to oracledb with filehelpers? Please provide some sample code for reference.

If you save the spreadsheet data as .csv files it is relatively straightforward to import it into Oracle using SQLLoader or external tables. Because we can use SQL with external tables they are generally eaiser to work with, and so are preferable to SQLLoader in almost all cases. SQL*Loader is the betterchoice when dealing with huuuuge amounts of data and when ultra-fast loading is paramount.
Find out more about external tables here. You'll find the equivalent reference for SQL*Loader here.
A simple and relatively fool-proof way to do that for one-off tasks is to create a new column in the excel sheet, containing a formula like that:
="insert into foobar values('"&A1&"','"&A2&"');"
Copy that to all rows, then copy the whole column into an editor and run it in SQL*Plus or sql developer.
I am using Sqlloader to upload data from CSV to Oracle DB.
