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

Choosing the Right Microsoft Reporting Technology Part 6: Making the Decision

We’ve completed reviewing the major Microsoft tools and now you have to make “The Decision”.  Which tool(s) is the best fit for the reporting needs?  Remember just picking one tool and using it for all reports may not be the best decision because you are missing out on a lot of the benefits of other tools. 

One tool I like to use that helps me make a decision like this is a decision matrix.  With a decision matrix you provide the possible options, which for us has been the following tools:

You also provide the factors that are important to you in making a decision.  You can see in the screenshot below I’m considering tools based on:

  • Ad Hoc Reporting
  • Content Sharing
  • User Flexibility
  • Developer Flexibility
  • Time to Develop


Within the matrix you rate each of the tools (0-100) in their capabilities of the factors you’re considering.  This rating should only be done once. 

Some factors to making a reporting decision may be more important than others depending on the need.  For example, for one report Ad Hoc Reporting may be the most important thing while another report Content Sharing may be the most important thing.  That’s why you sign a relative weight (0-10) to each decision you need to make.  That way if Ad Hoc Reporting is most important than rate it higher than the other factors.  Again, this weighting system would be changed for each report you need to make a decision on choosing a tool.

Using a tool like a Decision Matrix can help you make decisions quickly and with more confidence.  I hope this series has been helpful.  If you need to catch up on previous posts follow the links below.
