Error while calling procedure from python sqlalchemy.exc.DatabaseError: (pyhdb.exceptions.DatabaseError) invalid argument: Input parameter is inadequate as table parameter:

parameter one is table type in and second is a varchar out

I am adding the code snippet which i am trying with

engine = create_engine("hana+pyhdb://{username}:{password}@{host}:{port}".format(username='username', password='password', host='hostname', port='30015'))

output="

Dear Arunkumar

Actually the DB procedure a table[] is expected... not the string of data.

So you may have to write something like this

DO BEGIN    

-- select values from table to fill the table
   tabledata = SELECT * from xyz;            
        
    
 test=engine.execute('call SCHEMA.PROC(?,?)',(tabledata,output))
END;
