This is the first time we decided to use QlikSense. So I am a newbie.
I have developed a sheet for a table report.
I loaded a lot of data and I made a lot of renames on the fields when they are loaded from the database to look pretier for searching in the Analytics tab.
In order to show my progress to my boss I had to publish my work. He wanted to use another type of user. So I published the App, but I lost the ability to edit anything especially the data loading. Unfortunately that means I have to restart my work.
Any suggestions on how to restore my progress?
(It sounds to be an off-topic question probably...because there is no code in here)

Salesforce has two different UIs and in accordance with it, it has the possibility to store attached files differently.
Two files were uploaded via the classic UI and they are marked as 'attachments'. Other files were uploaded through the new UI and they are marked as 'files'.
I want to upload all of these files using REST API. I cannot find the proper documentation. Can somebody help me with this?
That's not 100% true. In SF Classic UI you were able to upload Files too. It's "just" about knowing the right API name of the table and you'll find lots of examples online.
Attachment and Document objects have exactly same API names, you can view their definitions in SOAP API definition or in REST API explorer (there was something which you can still see in screenshot in here, seems to be down now, maybe they're moving it to another area in documentation...)
The Files (incl. "Chatter Files") are stored in ContentDocument and ContentVersion object. The name is unexpected because long time ago SF purchased another company's product and it was called "Salesforce Content". In beginning it was bit of mess, now it's better integrated into whole platform but still some things lurk like File folders can be called Libraries sometimes in documentation but actual API name is ContentWorkspace. The entity relationship diagram can help a bit: https://developer.salesforce.com/docs/atlas.en-us.api.meta/api/sforce_api_erd_content.htm
ContentDocument is a header to which many places in SF link (imagine file wasting space on disk only once but being cross-linked from multiple records). It can have at least 1 version and if you need to update the document - you'd upload new version but all links in org wouldn't change, they'd still link to header.
So, how to use it?
REST API guide: https://developer.salesforce.com/docs/atlas.en-us.api_rest.meta/api_rest/dome_sobject_insert_update_blob.htm
or maybe Chatter API guide (you tagged it with chatter so chances are you already use it): https://developer.salesforce.com/docs/atlas.en-us.chatterapi.meta/chatterapi/connect_resources_files.htm
some of my answers here might help (shameless plug). They're about upload and reading data too and one is even about data loader... but you might experiment with exporting files first, get familiar with structure before you load?

edit: Sorry about the wrong title before. StackOverflow had saved an old question I was going to ask, and I didn't notice the title
I'm working with Tableau and have created a couple of Dashboards and have included a data source. The Data source is fairly big, around 10.000.000 rows.
My problem is that when I try to publish it to Tableau Server, it gets stuck at "Sending data to server" (See included picture). The server is not down as I can publish other Dashboards, where a smaller data source is included.
Has someone here had similar problems? In that case how can I fix it?
Any help would be greatly appreciated.
You can try to cut your datasource to 1 raw and put all data back when it will be already published. It's should work for sources like table or views in database for example.

This sample URL displays the report executed and saved in the archive. Before downloading, I need to specify an additional condition on one of the columns. For example, City = Samplesity How can this be implemented with the help of Microstrategy url api?
You could use a view filter (with a prompt) in the report and answer the prompt via MicroStrategy URLAPI. The problem would be that the prompt will be showed also to the users (if the report is executed with a subscription, then no problem).
Using a report in this way doesn't make much sense to me, better in this case to use a cube and create a report with a prompted view filter on top of it.
If by "saved in the archive" you mean stored in the History List then there is not much to do here. The History List contains an execution of a report, you cannot really modify it.
If you are looking for a way to filter on old version of your data you have to find another solution, like keeping historical version of the data.
There is plenty of documentation out there for looking up what content DB a site collection uses in SharePoint. However, I'm looking for the reverse. I have a specific DB, and I need to know where (what URL's) it's content is referenced or displayed.
We have a DB that has been partially corrupted and in need of restoring. It appears the only clean backup we have of it is relatively old. However, at first glance the library we know to be using it is lightly used. There has been no new content added to it since our backup was taken.
I am looking for a way to confirm that restoring from this backup wont unknowingly overwrite some critical data somewhere else.
In doing more digging, I did find another SO post that was able to get me the information I needed.
How to see all site collections in a specific content DB
-ContentDatabase contentdbname | select url, #{label="Size";Expression={$_.usage.storage}}
In navigating to the returned URL, I found recently added data. So that now rules out the restore.
Sweet..I bought myself a 1TB portable harddrives this week. Don't you just love how much data you could store on one of these disks? The fact that I could store my bluray rips on to my portable harddisk and that my lg lcd tv can do HD rips right from the drive - that's amazing practicality right there! However, life it seems, is never so simple. I have 100s of movies unorganized in one huge folder, which is exactly what I needed to annoy myself while browsing the same on my tv to play a single movie. That got me thinking...
What if I had an automated way to organize movies into folders such that my folder-browsing-on-a-lcd-tv-or-a-comp would make my life a little easy?
I started thinking about this... I browsed a little in this context and I realized that if only I could "tag my movies somehow and create folders on-the-fly based on tags using hardlinks", I would have addressed my problem. I googled a bit to find software that works in the above fashion, only to find none.
A few more days of serious thought (as you know by now.. I think a lot.. and I guess this question is starting to sound like a blog rant/post of sorts...), in the interest of humanity, I thought I should come up with a generic way to address this: What if someone wanted to organize photos... organize music.. organize software?!
Turned my grey cells off for a while and here is an approach I came up with to solving my what-if scenario.
Tag / Group tag individual files (rely on a slick GUI to do it fast and do it good) - Adobe Flex/Eclipse RCP to do this?
Create hardlinks to each of the tagged files.
The first point is self-explanatory. The second (coz I am talking windows here), refers to making use of mklink.exe.
Consider a scenario where I have 2 movie files: I have a movie file "Transformers.avi" tagged as "english, action, bluray, sci-fi, imdb-top-50, must-watch-with-kids" and another movie file "The Specialist.avi" tagged as "english, bluray, thriller, adult". Here are a few of the possible locations I want to see my Transformers to be found:
[root directory]->all-tags->english
[root directory]->all-tags->bluray
[root directory]->all-tags->english->all-tags->bluray
[root directory]->all-tags->bluray->all-tags->action
[root direcotry]->all-tags->english->all-tags->action->bluray->all-tags->imdb-top-50
Given that windows has a limit of 1024 hardlinks to a single file, I probably would be allowed 7 unique tags per file. Each sub-folder will have an "all-tags" folder. Having it named "all-tags" makes it more accessible when order by name.
I believe this approach when automated to let you configure tags you want and where the hardlinks are created for you, helps you organize stuff effectively.
I don't know if there are better things out there. I would like your inputs on this approach and other possible ideas. I would like to gather inputs here and release something to sourceforge for everyone to use in a couple of weeks. I am sure, I can count on your positive response as always.
I believe hardlinks are not a good approach. Reason? A standalone player won't play them, and I wouldn't like a program who's made for tagging to tell me to stop making so many tags because of a Windows limitation on hardlinks (remembering each tag will increment the number of links exponentially).
Plus, "help" is not a good tag.
And I've had an idea once that I'm still planning to make some day to sort my own files - put the files in a big storage each below a GUID foldername (filename untouched) and store metadata in a sqlite database to be used by a smart file browser.
I was considering doing something similar to this with music for detecting duplicate songs and auto-organize funcationality.
For your application, I wouldn't recommend using any shell programs through Java. Exception handling becomes difficult, and your application becomes bound by the shell interface and implementation (i.e. windows versions or installations affect your application behavior).
I would use a database with a few tables: Files, Tags, and an association table.
The Files table would list the physical location of each file, the filename, and a unique identifier. This way, you can maintain information about each file without having to modify it for every tag association.
The Tags table would list each tag, and any metadata you want to store for each tag.
A third table, maybe 'FileTags' would store the assocation between tags and files. When adding tags to the stack, you would add a statement to the WHERE clause, and the list of files with all of the tags would be returned. This structure would also allow open your codebase up to other designs, such as include/exclude (autocomplete with X buttons), or possibly search.
If implemented in Java, your app would be platform independent, and would allow a very large number of tags and files. You can then use the system default application for opening the media file, and the user can make the selection in their native OS.
