DAX Query View: Game Changed?
The introduction of a groundbreaking feature in Power BI Desktop that promises to revolutionize your data analytics workflow—the DAX Query View. This powerful tool is designed to significantly enhance our interaction with data, thereby increasing both efficiency and insight in our work.
What is DAX Query View?
DAX Query View is a new feature in Power BI Desktop that allows you to run and visualize DAX queries directly within the application. This means you no longer need external tools to see the results of your DAX queries. With DAX Query View, you can execute your queries and instantly view the top 100 rows of your data right within Power BI.
Features of DAX Query View
You can now write and run DAX queries directly in Power BI Desktop. This integration simplifies the process, allowing you to see query results immediately.
The feature displays the top 100 rows of data from your queries, giving you a quick and clear understanding of your data outputs without creating additional model objects.
Generate detailed statistics for each column, including counts, distinct values, minimums, maximums, medians, and standard deviations. This helps you better understand the data characteristics and distributions.
The editor includes features like syntax highlighting and auto-completion, similar to what you experience in Visual Studio Code, making it easier to write complex queries.
DAX Query View Impacts Power BI Development
By allowing you to see the data returned by your queries directly in Power BI, DAX Query View significantly reduces the time spent switching between tools for debugging and testing.
The ability to retrieve and visualize metadata and statistics directly within the tool helps you gain deeper insights into your data model, facilitating better decision-making and model optimization.

Integrating DAX Query capabilities directly in Power BI speeds up the development process. You can now write, test, and refine your DAX queries more efficiently, leading to quicker iterations and more robust reports.
DAX Query View vs. SQL
While DAX queries might seem similar to SQL at first glance, there are distinct differences:
SQL is used for querying and managing databases, whereas DAX is designed specifically for data modeling and reporting in Power BI.
DAX is tailored to Power BI’s data model, allowing for intricate calculations and table manipulations directly tied to the visuals in your reports. Unlike SQL, which creates and manipulates objects in the database, DAX queries return data directly for analysis without altering the underlying model.
Every visual in Power BI is backed by a DAX query. The DAX Query View lets you see and understand these queries, making it easier to optimize performance and troubleshoot issues.

6 个月Interesting, but I’ll have to look at this more. It seems like this would force me to build in Power BI prior to proof of concept (for specific metrics) which seems like extra work. Generally, my process is to write the code, drop it into Excel, run statistics, maybe regression, and then let the business use it to determine if it is truly helpful. Once validated and the business use is determined to be worthwhile, I move it to my intermediate platform. Then, I build my Power BI visualization. By the time I get there, I have little reason to see the DAX query other than for the build of the metrics. Maybe I’m under thinking this.
