Erreur SQL lors de la génération de la commande SQL avec Doctrine PHP

Question

J'utilise Doctrine sur mon application web PHP avec une base de données MySQL. J'ai un petit problème avec ma demande:

$q = Doctrine_Query::create() 
    ->select('event.EventDate, event.EventId, player.PlayerId, player.FirstName, 
      player.LastName, player.Login, player.Email, 
      event_period.EventPeriodId, event.Type, event.Description, 
      period.StartHour, period.EndHour, player_event_period.Participate, 
      event_period.CourtNumber') 
    ->from('Event event, Player player, Period period') 
    ->leftJoin('player.PlayerEventPeriod player_event_period') 
    ->leftJoin('player_event_period.EventPeriod event_period') 
    ->where('period.PeriodId = event_period.PeriodId') 
    ->andWhere('event.EventId = event_period.EventId'); 

si je montre quelle est la commande MySQL généré, je peux voir

SELECT e.eventid AS e__eventid, e.eventdate AS e__eventdate, e.type AS e__type, e.description AS e__description, p.playerid AS p__playerid, p.firstname AS p__firstname, p.lastname AS p__lastname, p.login AS p__login, p.email AS p__email, p2.periodid AS p2__periodid, p2.starthour AS p2__starthour, p2.endhour AS p2__endhour, p3.playereventperiodid AS p3__playereventperiodid, p3.participate AS p3__participate, e2.eventperiodid AS e2__eventperiodid, e2.courtnumber AS e2__courtnumber 
FROM event e, player p, period p2 
LEFT JOIN player_event_period p3 ON p.playerid = p3.playerid 
LEFT JOIN event_period e2 ON p3.eventperiodid = e2.eventperiodid 
WHERE (
p2.periodid = e2.periodid 
AND e.eventid = e2.eventid 
); 

J'obtiens l'erreur:

#1054 - Unknown column 'p.playerid' in 'on clause' 

Quel est le problème avec ma demande ?

Nous vous remercions à l'avance

EDIT:

Si cela pourrait vous aider. J'ai ajouté le script qui crée mes tables de base de données.

Answer 1

Je ne sais pas comment vos modèles regardent mais ne table appelé « joueur » ont une colonne appelée « playerid » en elle?

C'est ce dont se plaint mysql. [Edit]
Je pense que Doctrine préfère les noms de colonnes en minuscules. (Je ne me souviens pas si MySQL est sensible à la casse des noms de colonnes ...)

Answer 2

La sensibilité aux majuscules des noms de colonnes MySQL dépend de la configuration de la base de données/du schéma/des tables, mais il semble que la vôtre soit sensible à la casse.

Vous n'avez pas fourni les définitions d'entité, donc je devine le problème, mais essayez de définir le nom de la colonne.

Par exemple, pour identification du joueur l'annotation serait:

/** 
* @Column(name="PlayerId", type="integer", length=11, nullable=false) 
* @Id 
* GeneratedValue(strategy="AUTO") 
*/ 
protected $PlayerId;
