I'm using Google Data Studio to visualize results from various queries (from different tables within the same BigQuery-database).
For this reason, I created and use multiple data-sources-connectors. Each one of them has a SQL query included and makes use of an defined input parameter (which can be changed by report editors) - called "userid". It is the same id for all queries and resulting charts.
However, when I click "Manage URL parameters", I'm not allowed to use the same URL parameter for more than one data source (instead they are called ds0, ds1, ds2 etc - although they all end up being used as "userid").
If I add a data source under File - Report Settings, a new field "userid" appears, which I can alter - this will update ALL charts in the report with the very same userid (as expected). This works, but I do want to make use of an url which delivers an report with all updated queries depending on ONE userid.
Therefore, I guess I'm overseeing something - it should be possible to just use one query parameter to update the same "userid" for all queries in all data connectors? Or have I overlooked the possibility to fire multiple queries within one data source connector? Or is it expected to create a looong url full of redundant query parameters in this case?
I'm curious for your input!
Best regards :)
If you group the elements that you want to control with the same parameter (select and then shift G) then it will give you options to select the data source and the params box to apply to the group.
