Change Database dynamically

[Saumil]

Hey there.

This is saumil here. I am new to the power bi and I do have a question. I hope you guys makes me clear about it.

I have a multi-tenant app and have one power bi report. In that report I have a Tenant parameter with the list of values "Tenant1" & "Tenant2". Please refer the screenshot. Now I am using this paramter value to connect to the database as dbname.

When I publish the report to the power bi service then from there I can able to change the Tenant value and it loads the report accordingly.

Wha I wanted to do is, I want to change the database name from my angular or .net core application by passing the value of Tenant Parameter.

So, can you guys help me out on this?

@Anonymous thanks for your reply. Now what if i want to set the value of that parameter from my client app which made in .net mvc?

Thanks for your reply. I have completed at this level but once I publish that report to power bi server and when I try to pass the parameter value from my angular or .net mvc app then it does not change the database name.

So, I want to pass that dynamic parameter from my client app and needs to get the report details as per the login user's database.

Thanks

Hi @Saumil ,

Please try below steps:

1. Create a Parameter:
- Open your Power BI Desktop.
- Go to the Home tab and click on Manage Parameters.
- Create a new parameter (e.g., "DatabaseName") and set its value to the initial database name (e.g., "AdventureWorksDW2012").

2. Modify Your Data Source:
- Connect to your data source (e.g., SQL Server database) using Power Query.
- In the Power Query Editor, locate the step where you specify the database connection.
- Instead of hard-coding the database name, replace it with the parameter you created (e.g., '#"AdventureWorksDW2012"').

3. Change the Data Source Dynamically:
- Now you can go to the query where you want the source to be dynamically changing.
- Click on the relevant source step (e.g., the one specifying the database name).
- Set the database name to come from the parameter you created earlier (e.g., '#"AdventureWorksDW2017BIG"').
- That's it! Your report will now adapt to the new data source without manual intervention.
