... But what to do with ZSQL methods? I was create Python script called ZSQL_query:

## Script (Python) "ZSQL_query" ... ##parameters=my_string .... result=context.folder_few_levels_above.ZSQL_query(my_string=my_string) return len(result)

But I was receive error:

Apparently, the problem occurs when your Python Script "ZSQL_query" (not the ZSQL method) is called. Apparently, the Python Script is called without parameters but it requires a parameter "my_string". -- Dieter
