In a recent video, Austin Libal, a seasoned trainer at Pragmatic Works specializing in Microsoft Fabric and PowerBI, demonstrated two powerful methods to connect to Lakehouse tables within the PowerBI Report Builder tool. This tool is instrumental for creating paginated reports with a Pixel Perfect capability, allowing users to precisely format their reports for print or PDF distribution.
Method 1: Connecting through PowerBI Data Set
Data Source Creation:
Austin initiates the process within the PowerBI service workspace.
Demonstrates how to create a new data source by right-clicking in the report data pane.
Alternatively, shows the option to add a connection to a PowerBI data set.
Selecting Workspace and Data Set:
Austin selects the desired workspace (Learn with the Nerds) and the Adventure Works data set.
This approach provides a seamless connection to the PowerBI data set, enabling subsequent report creation.
Query Design with Dax:
Entering the query designer, Austin explores the graphical user interface for creating Dax queries.
Discusses the flexibility of leveraging measures, KPI indicators, and various columns for data selection.
Acknowledges that Dax may not be everyone's preferred language but offers courses for deeper understanding.
Method 2: Connecting through SQL Endpoint
Acquiring SQL Endpoint:
Austin emphasizes the need for a SQL endpoint from the Fabric Lakehouse.
Guides users on obtaining the SQL connection string from the settings.
Traditional Data Source Addition:
Demonstrates the creation of a more traditional data source within PowerBI Report Builder.
Names the data source (Adventure Works Lake Database) and selects Microsoft Azure SQL Database as the connection type.
Building Connection String:
Utilizes the build connection string option, pasting the SQL endpoint for logical connection.
Chooses Azure Active Directory authentication for security.
Query Design with SQL:
Creates a new data set using the SQL data source.
Shifts from Dax to SQL, showcasing the ability to run SQL queries and select specific tables (e.g., dim date).
Enhancing Paginated Reports: Tips and Resources
Dax vs. SQL:
Austin acknowledges the preference for SQL over Dax for certain users.
Encourages exploration of both languages and highlights Pragmatic Works' courses for in-depth learning.
Paginated Boot Camps:
