Is the SQL function really working?

Hello dear team,
I want to use the SQL function "Tables: Run SQL query on data table and return data table"
I copied the statement from support doc "SELECT * FROM CatalyticTable"
However the action reports with error "SQL logic error.no such table: CatalyticTable".
See picture 1.

Meanwhile I downloaded the SQL demo workflow from support site and imported the file.
As a result all actions are empty in the demo workflow.
See picture 2.

Please support me how to use the SQL correctly.
