Power BI Publish to Web for Anonymous Access is Here

Earlier this week on Wednesday the Microsoft Power BI made an incredibly exciting announcement and released Power BI “publish to web” as a preview feature. This is HUUUUGE news! This was probably the top requested feature and its finally here thanks to the hard work and dedication of the Microsoft Power BI team!

Power BI “publish to web” allows you to easily expose a Power BI report to the world through an iframe that can be embedded wherever you like.

To publish your Power BI report to the web, log into your Power BI site.

Find the report that you want to share and click File in the top left.
Power BI publish to web

You’ll see a message pop up box similar to below. Click the yellow button to create the embed code.

This is where you’ll see a very important warning!
WARNING: Reports that you expose through the “publish to web” feature will be visible to everyone on the internet! This means NO AUTHENTICATION is required to view the report that is embedded in your application.

Once you do that, you’ll receive an embed code that you can then use to expose your Power BI report within your blog as seen below!

As you can see the report maintains all the interactivity features of Power BI. And as your Power BI report updates and changes, those changes will be reflected in your embedded Power BI reports!

Pretty awesome!

Non Empty vs NonEmpty

Hey everyone, in this blog I want to address a very common MDX Question. What is the difference between the NON EMPTY keyword and NONEMPTY function? To take it a step further which one should you use?

Non Empty keyword VS NONEMPTY Function.

The big difference between the NON EMPTY keyword and the NONEMPTY function is when the evaluation occurs in the MDX. The NON EMPTY keyword is the last thing that is evaluated, in other words after all axes have been evaluated then the NON EMPTY keyword is executed to remove any empty space from the final result set. The NONEMPTY function is evaluated when the specific axis is evaluated.

Should I use NON EMPTY keyword or NONEMPTY function?

Ok Mitchell, so you told me when each of these are evaluated but really you haven’t told me anything up until this point. Can you tell me which one I should use already? Well, unfortunately, it depends. Let’s walk through an example of each using the BOTTOMCOUNT function.


In this example I’m returning the bottom ten selling products for internet sales. Notice that I have returned all products that have no internet sales, this is not necessarily a bad thing, maybe you want to return products that don’t have sales.


However if you don’t want to return these products then we can try using the NON EMPTY keyword. In the below example you can see the results when I add NON EMPTY to the ROWS axis.


WHOOOAAA, what happened?? A lot of people would have expected the results here to show the bottom ten products that DID have sales. However, that is not the case, remember that I said the NON EMPTY keyword is evaluated LAST after all axes have been evaluated. This means that first the bottom ten selling products which have $0 in sales are first returned and then the NON EMPTY keyword removes all that empty space from the final result.

BOTTOMCOUNT function with NONEMPTY function.

So let’s try this again, if you want to return the bottom ten products that had sales then we must first remove the empty space before using the BottomCount function. Take a look at the code below:


In this code we first remove the empty space before using the BOTTOMCOUNT function. The result is we return the bottom ten products that had internet sales. Once again neither one is right or wrong here it just depends on what you want in your final result.

There is a very common misconception that the NONEM

Sample Interview Questions for SSIS jobs

I don't know about you, but for some reason, one of the most terrifying experiences for me is interviewing for a new job.  There are a few things that you can do to prepare yourself for an upcoming interview and make it slightly less terrifying.  You can work on improving your communication skills and managing whatever nervous habits you may have developed over the years.  Or spend some time thinking of some questions that you would like to ask your hopefully-soon-to-be employer, so that when they ask you, "so, do you have any questions for us?", you can say something other than "nope, I'm good" ("Nope, I'm good" isn't a very impressive response... Just ask all of your unemployed friends.  Try to always ask at least one question about the job you'll be doing or the environment you'll be working in).  The most ideal preparation aide (not H) would be having a cheat sheet or a list of the questions that you will be asked in the interview.  Well here's the best I can do for you.  Here are some real-world questions that I have encountered while interviewing for SSIS specific jobs.  (Along with some answers)

Explain the difference between Synchronous and Asynchronous components.  A synchronous component will reuse the input buffer because the number of output rows is exactly the same as the number of input rows.  This basically means that a synchronous component can start before the previous component completes.  With an asynchronous component, a new buffer is used because there can be a different number of output rows than input rows.  And this means that in some cases the component may need to wait for the previous component to fully complete before it can even start.

What can you use an OLE DB Command for?  The OLE DB Command is a pretty simple transformation that's available within a Data Flow that can run a SQL statement that can insert, update, or delete records to, in, or from a desired table.  It's good to keep in mind that this transformation initiates a row-by-row operation, so you may experience some performance limitations when dealing with large amounts of data.

What are checkpoints and why are they important?  Checkpoints offer the ability to restart failed package at a specified point.  If you have configured a checkpoint on a package, information about that package will be sent to a checkpoint file.  In the event of a failure, the package will use this information to know where to start.  In the event of a successful completion, this file is automatically deleted.

What are the benefits or advantages of using Raw Files in ETL?  Aside from the possibly that a Raw File might be your only option as a source.  Raw files do offer a slightly better advantage when it comes to speed and performance.

What is a Common Table Expression?  A common table expression is basically a result set that is temporarily stored within the scope of a SELECT, UPDATE, INSERT, or DELETE statement.  The data stored from the common table expression can be used by the SQL statement that follows it.

What can you tell me about Ralph Kimball?  Ralph Kimball is an author on the topic of data warehousing and BI.  He has been regarded as one of the original architects of data warehousing.  Kimball has always had the firm belief that data warehouses should fast and understandable.  Oh, and he developed this whole methodology of dimensional modeling.  There is that.  (It's also probably a good idea to know the basic idea and structure of dimensional modeling)

I hope this helps as you prepare for your next SSIS interview!  Good luck!
