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.
warning 2

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!

MDX NON EMPTY KEYWORD VS NONEMPTY FUNCTION

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.

BOTTOMCOUNT FUNCTION with NON EMPTY Keyword

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.

NON EMPTY Keyword vs. NONEMPTY Function – Performance

There is a very common misconception that the NONEM

Welcome to the first of my “SQLBIGeek’s Function Friday” blog series. I understand that I am posting it on Sunday for this first post, rather than Friday. However, going forward I am going to post a new function each Friday. Whether it be cleaning up an old function that I have come across (written by others or myself J) or it is just something that I have written lately. Either way, I hope that you enjoy the series and that you can get some useful ideas or functions to use in your environment.

 

 

I recently came across a function that returned the first day of the quarter based on a date value supplied. At first glance, it appeared to be a little longer than it needed to be. I could definitely see where they were going with it and why they did it that way, but I thought that I might be able to shrink it down a little bit with less typing (minus the commenting of course). Script 1 below shows us this function.

 

Script 1: Original Function

CREATE FUNCTION [dbo].[ufn_GetTheFirstDayOfTheQuarter]

(

      @InDate DATETIME

)

RETURNS DATETIME

BEGIN

 

    DECLARE @OutDate DATETIME

    SET @OutDate =

            CAST(YEAR(@InDate) AS VARCHAR(4)) +

            CASE

                WHEN MONTH(@InDate) IN (1,2,3) THEN '/01/01'

                WHEN MONTH(@InDate) IN (4,5,6) THEN '/04/01'

                WHEN MONTH(@InDate) IN (7,8,9) THEN '/07/01'

                WHEN MONTH(@InDate) IN (10,11,12) THEN '/10/01'

            END

 

    RETURN @OutDate

 

END

 

--Execute it a few times

SELECT dbo.ufn_GetTheFirstDayOfTheQuarter ('3/21/2010')

SELECT dbo.ufn_GetTheFirstDayOfTheQuarter ('6/21/2010')

SELECT dbo.ufn_GetTheFirstDayOfTheQuarter ('9/21/2010')

SELECT dbo.ufn_GetTheFirstDayOfTheQuarter ('12/21/2010')

 

--Clean up my function

DROP FUNCTION dbo.ufn_GetTheFirstDayOfTheQuarter

 

I went home that night and looked at the query again and thought for a minute… then I started typing. The results are shown in script 2 and 3 below. Using the DATEDIFF and DATEADD functions, I was able to determine the first day of the quarter in one line without a case statement.

Script 2 was a quick test query that I came up with.

 

Script 2: Determine First Date in Quarter Select Statement

DECLARE @pInputDate SMALLDATETIME = '9/21/2010'

SELECT DATEPART(Quarter,@pInputDate) AS Quarter

      , DATEADD(qq, DATEDIFF(qq,0,@pInputDate), 0) AS FirstDayOfQuarter 

 

So using my slightly simplified select script above and incorporating it into a function would look something like that shown in script 3.

 

Script 3: Determine First Date in Quarter Function

CREATE FUNCTION [dbo].[BKM_ufn_GetTheFirstDayOfTheQuarter]

(

      @InDate    DATETIME

Purpose:          Return the first day of the quarter based on date

)

RETURNS DATETIME

BEGIN

 

      DECLARE @OutDate DATETIME

SET @OutDate = DATEADD(qq, DATEDIFF(qq,0,@InDate), 0)

     

      RETURN @OutDate

END

GO

 

--Execute it a few times

SELECT dbo.BKM_ufn_GetTheFirstDayOfTheQuarter ('3/21/2010')

SELECT dbo.BKM_ufn_GetTheFirstDayOfTheQuarter ('6/21/2010')

SELECT dbo.BKM_ufn_GetTheFirstDayOfTheQuarter ('9/21/2010')

SELECT dbo.BKM_ufn_GetTheFirstDayOfTheQuarter ('12/21/2010')

 

--Clean up my function

DROP FUNCTION dbo.BKM_ufn_GetTheFirstDayOfTheQuarter 

 

I understand that sometimes it takes more typing to make queries perform better, but in this case the query plan is exactly the same. Figure 1 shows the execution plan of executing each of the functions for 3/21/2010.

** Note: This is not the only way that one could determine the first date of the quarter, but IMHO is the easiest to understand and quite a bit less typing J **

 

Please be sure to return for the next BISQLGeek's Function Friday, as I will show you how to parse through some crazy integer values that are representative of duration. I hope that you have enjoyed this post. If you did, please take just a moment to rate it below! Also, if you don’t already, please be sure to follow me on twitter at @briankmcdonald.
