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

***UPDATE***

The new SSIS connectors for Oracle and Teradata are available now.

http://blogs.msdn.com/b/mattm/archive/2012/04/04/microsoft-connectors-v2-0-for-oracle-and-teradata-now-available.aspx

FYI the 2.0 version is for 2012 only… You want the 1.2 version for 2008

---Thanks to Mike Davis & Devin Knight for the info!

Using the Microsoft Connector for Oracle by Attunity with SQL Server 2008 Integration Services

http://msdn.microsoft.com/en-us/library/ee470675%28v=sql.100%29.aspx

-------------------------------------------------------------------------------

 

I was recently tasked with creating a test package to check the performance of SSIS loading data from MS SQL Server 2008 to an Oracle database and loading data from Oracle to MS SQL Server.

My tests have only been performed on a 32bit laptop running Windows XP (Yeah, I know...)

Here are the steps I took:

  1. Install Oracle Developer Suite 10g (10.1.2.0.2) (including Forms and Designer)  http://www.oracle.com/technetwork/developer-tools/developer-suite/downloads/index.html  (for 64 bit test, you would just need to install the 64 bit version.)
  2. Edit C:\DevSuiteHome_1\NETWORK\ADMIN\TNSNAMES.ORA by appending the TNS information provided by your Oracle DBA.
  3. Edit C:\WINDOWS\system32\drivers\etc\hosts using notepad.  Add the host entries provided by your Oracle DBA to the file.
  4. Create a new SSIS package, add a connection manager of type Native OLE DB\Microsoft OLE DB Provider for Oracle.  Enter SOMETEXT (see example TNS Entry below) in Server name, and the user name and password provided.  Click Test Connection.
  5. Create an Execute SQL Task to truncate the Oracle table you will be loading.  Must be coded like this:  truncate table "SOME_TEST"."Movies"    **NOTE: SOME_TEST is the schema name.
  6. Create another Execute SQL Task to truncate a SQL Server table called Movies2.
  7. Create a data flow to pull data from SQL Server to Oracle.
  8. Create a data flow to pull that data from Oracle into another new table in SQL Server (Movies2).
  9. Data Types are tricky.  You may have to cast as nvarchar or numeric(38,0) when pulling from SQL Server and use derived column transformations when pulling from Oracle.
  10. For the Oracle Source & Destination components, right click and select Show Advanced Editor.  Under component properties, set AlwaysUseDefaultCodePage to True.

1.       

Now comes the fun part...
Using the Oracle Connection managers that come w/ SQL Server, it took approximately 10 minutes 45 seconds to pull about 45,000 rows of 2 columns full circle.   (That is slow!)
My good buddy, Stephen Bowley, told me about the Attunity drivers that you can download from Microsoft's website.

http://www.microsoft.com/downloads/en/details.aspx?familyid=6732934C-2EEA-4A7F-85A8-8BA102E6B631&displaylang=en

These drivers only took 45 seconds to complete the same task.  It creates new data flow components specifically for Oracle source and Oracle destination (similar to the OLE DB Source / Destination components; but, specifically for Oracle.)

-------------------------------------------------------------------------------

ExSample TNS Entry: 

 

SOMETEXT =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = SOMESERVERA)(PORT = 1521))

    (ADDRESS = (PROTOCOL = TCP)(HOST = SOMESERVERB)(PORT = 1521))

    (LOAD_BALANCE = yes)

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = APPGA)

    )

  )

-------------------------------------------------------------------------------

Example Hosts entry:

86.7.5.309     SOMESERVERA

12.34.56.78   SOMESERVERB

-------------------------------------------------------------------------------

The following are the instructions my buddy Stephen sent me.  I didn't have to follow these b/c my test was only done on a 32 bit laptop.  I think he was developing on a 64bit environment.  I will post them here in the event they might help someone else.

 

If server is 64bit, Then we have to install both the 

32bit and 64bit drivers for the attunity connector utility. 

Can be found at:

http://www.microsoft.com/downloads/en/details.aspx?familyid=6732934C-2EEA-4A7F-85A8-8BA102E6B631&displaylang=en

Once installed, you'll have to installed the correct Oracle Client tools. 

This also requires you install the 32bit and 64bit versions. 

next you have to setup the Service Names on the DB box through oracle

using the Oracle Net Manager application. This has to be done for both 

32bit and 64bit installations. Name the service names the same. Remember

these are where you use the connection information of the oracle server.

Make sure you can connect to the Oracle instance on server

through the SQL-Plus untility.

You'll probably have to create a new folder called "ProgramFilesx86" on the root of installation path of SQL Server.

Then COPY everything from the "Microsoft Visual Studio 9.0" folder in that. THEN ALL BIDS shortcuts needs to ref

that direcory otherwise the connector wont allow BIDS to manually run the package since BIDS is a 32 BIT application.

"I do not expect that Microsoft will write an Oracle fast loader - currently it comes in around number 999 in my list of 1000 features for next version, just slightly ahead of recompiling for Linux." - Donald Farmer
