Dynamically change data source from SQL database

[BusinessAnalyst]

Dear everyone,

I have several tables in SQL databases, for example: table1, table2, table3, table4. All are at the same server, same database, share the same format, same number and title of columns.

I want to import those table from SQL server, customize them with SQL Scripts.

Then I want to have a slicer visual which contains the list of all tables

Then I want to create a function to change data source dynamically, import different table to power bi desktop when I select a table name from slicer.

Is that possible?

Can you please help with an example?

Many thanks in advance!
Cindy

Hi @Cindy,

Some additions to the wonderful post of @ImkeF. The feature changing parameters in the Service is on the way. 

Another easier workaround is changing the parameters directly without a slicer.

Best Regards,

It's a bit of a hack on only works in Power BI Desktop, so not in the service: http://www.thebiccountant.com/2017/03/22/use-slicers-for-query-parameters-in-powerbi/

A different option would be to always load all tables into one big table with an additional column indicating the source.

The users can then do the same "source-selection" on the canvas and the data will be dynamically filtered instantly without having to refresh again.

Dear Imke,

Thanks very much for your solution. The problem is tables on SQL server are generated on monthly basis only. It means that, we only have tables up till present, and no future tables. For example this month is April 2018, then there is no table for May 2018.

It’s fine if it’s only work on power bi desktop. My idea is that we don’t need to go back to advanced editor to edit the query (change month number) every much.

Cheers,
Cindy

Especially with monthly tables I'd personally choose the large consolidated table-version instead.

Are you aware of parameters in Power BI? You can change them from the canvas-view as well without having to hack into your model.
