CQRS - Domain Exceptions Vs Events for Exceptional Scenarios -

i'm wondering if it's preferable publish events rather throw exceptions aggregates. say, have domain there requirement students of grade level can enroll sports. if call enrollforsports on student not satisfy criteria, should aggregate throw exception or publish event, particularly if other aggregates or process managers interested in result of process? if event published, doesn't mean there need corresponding internal event handler handle event when we're replaying, though event wouldn't change state of aggregate? if exception thrown, how other parties notified? can command handler catch exception , raise event? can events raised command handlers? principally speaking, command should either valid , executed, or invalid , not executed. idea spawning error events leaves somewhere in middle , feedback whomever sends command ambiguous , delayed. unnecessary complexity in domain. if throw exception come immediate feedback to client code sent command. ...

python - Getting first row from sqlalchemy -

i have following query: profiles = session.query(profile.name).filter(and_(profile.email == email, profile.password == password_hash)) how check if there row , how return first (should 1 if there match)? use query.one() one, , exactly 1 result. in other cases raise exception can handle: from sqlalchemy.orm.exc import noresultfound sqlalchemy.orm.exc import multipleresultsfound try: user = session.query(user).one() except multipleresultsfound, e: print e # deal except noresultfound, e: print e # deal there's query.first() , give first result of possibly many, without raising exceptions. since want deal case of there being no result or more thought, query.one() should use.

oracle - Is the use of the RETURNING INTO clause faster than a separate SELECT statement? -

1) update foo set bar = bar + 1 = 123; select bar var foo = 123; 2) update foo set bar = bar + 1 = 123 returning bar var; i assume second faster appears require 1 less trip database. true? just thought: often, applications need information row affected sql operation, example, generate report or take subsequent action. insert, update, , delete statements can include returning clause, returns column values affected row pl/sql variables or host variables. eliminates need select row after insert or update, or before delete. result, fewer network round trips, less server cpu time, fewer cursors, , less server memory required. taken oracle docs here
