DirectQuery in Power BI Desktop

In the latest Power BI Desktop a new Preview features was released that now allows you to connect using DirectQuery to either SQL Server or Azure SQL Databases.  DirectQuery is a really neat feature that allows you to point to the live version of the data source rather than importing the data into a data model in Power BI Desktop. 

Normally when you want to get an updated dataset in the Power BI Desktop you would have to manually click the refresh button (this can be automated in the Power BI Service), which would initiate a full reimport of your data.  This refresh could take a variable amount of time depending on how much data your have.  For instance, if you’re refreshing a very large table you may be waiting quite a while to see the newly added data. 

With DirectQuery data imports are not required because you’re always looking at a live version of the data.  Let me show you how it works!

Turning on the DirectQuery Preview

Now, because DirectQuery is still in Preview you must first activate the feature by navigating to File->Options and settings->Options->Preview Features then check DirectQuery for SQL Server and Azure SQL Database


Once you click OK you may be prompted to restart the Power BI Desktop to utilize the feature.

Using DirectQuery in Power BI Desktop

Next make a connection either to an On-Premises SQL Server or Azure SQL database.

Go to the Home ribbon and select Get Data then SQL Server.


Provide your Server and Database names then click OK. ***Do not use a SQL statement.  It is not currently supported with DirectQuery***


From the Navigator pane choose the table(s) you would like to use.  I’m just going to pick the DimProduct table for this example and then click Load.  You could select Edit and that would launch the Query Editor where you could manipulate the extract.  This would allow you to add any business rules needed to the data before visualizing it.


Next you will be prompted to select what you want to connect to the data. Again, Import means the data

Last week I wrote a blog explaining how the new tool inside Reporting Services 2008 R2 called Indicator will be help for displaying KPIs in Reporting Services.  Today I want to looks at another nice feature added to Reporting Services in R2 called Data Bar.  It’s a small but nice add to the product that gives it a little bit of an Excel look and feel. 

You may already know there is a nice but simply feature in Excel to help you compare data called Data Bars shown below, shown below.


This same functionality with even the same name has been added to Reporting Services.  It works just like any chart that you may have used in the past.  Drag it into a cell of a table then tell it what value you want represented on the bars.  Data Bars do not work on the detail level group so you may receive an error if you try and add one there.  You can add a label to the bars so you know what values are represented however it seems that the property to change the alignment of the label does not work properly yet, see below.  Hopefully this will be fixed when the product is officially released.
