@shan_chandra thainks for your reply. I tried it today but it didn't work. The result from display(Location_Path) is exactly the name of the location. The location is something like 

'abfss://abcd@xxxxx.dfs.core.windows.net/mytable'

Puting the location into the SQL works using the :Location_Path Parameter fails. Strange is, that I've additional parameters in my SQL like "Start_Date" and "End_Date" which works fine. Only the parameter for the location is not working.
