Execute a PL/SQL function (or procedure) from SQLAlchemy

Question

I have a legacy PL/SQL function:

getlogin(p_username in varchar2, p_password in varchar2) return boolean;

How can I execute this from SQLAlchem

Answer 1

If you're using .execute() on a connection method then you need a valid SQL statement. If getlogin is a function, this requires a SELECT:

result = DBSession.execute('select getlogin(:username, :password) from dual'
                          , {'username' : request.POST['username']
                             ,'password' : request.POST['password']});

As the error states, your SQL statement is invalid.
