Hi Marcel
The [0] notation works like you said
The other try, with the null being passed as an argument fails with an
exception :
com.orientechnologies.orient.core.exception.OCommandExecutionException:
Syntax error: function 'first' needs 1 argument(s) while has been received 2
apparently first only accepts one argument.
the [x] notation will do for now. It just surprised me to see first()
behaving like that.
Thanks so much for your help
