Answer 1

Yes, Power BI supports both dynamic query generation and table joins. Let's break down each of these:

For dynamic content :

• Parameters: These can be used in Power Query to create a dynamic source. For instance, you can have a parameter for a server name or a database name, and then use that parameter in your connection string. Users can input different values to the parameter to change the data source dynamically.- Query Functions: You can create custom functions in Power Query that can be called with different parameters to return different results.
• DAX Measures: DAX (Data Analysis Expressions) allows you to create dynamic measures based on user selections or filters applied in the report.

For the table joins :

• Power Query Editor: You can join tables using the Power Query Editor. Like SQL joins, you can perform inner, left outer, right outer, and full outer joins. You need to select the tables you want to join and specify the join keys.
• Relationships: Once the tables are loaded into Power BI's data model, you can also define their relationships. This isn't exactly like joining in a query but allows for related data to be used together in visuals, tables, and other report elements.
