我尝试使用sequelize将查询编码到数据库。这正是我想要的成绩单:
SELECT matches.uid_prop, matches.uid_player, matches.porcentaje, users.uid, profile_users.name, profile_users.profile, profile_users.birthday, profile_users.location
FROM (matches JOIN users ON (((matches.uid_prop = users.uid) AND (matches.uid_player = 11)) OR ((matches.uid_player = users.uid) AND (matches.uid_prop = 11)))) JOIN profile_users USING(uid)
WHERE (matches.uid_player = 11) OR (matches.uid_prop = 11);
我不知道是否应该更改关联以便按照我的意愿建立连接条件
Matches.belongsTo(User, {as: 'match_prop', foreignKey: 'uid_prop'});
User.hasMany(Matches, {as: 'user_prop', foreignKey: 'uid_prop'});
Matches.belongsTo(User, {as: 'match_player', foreignKey: 'uid_player'});
User.hasMany(Matches, {as: 'user_player', foreignKey: 'uid_player'});
或添加where并指定匹配和user之间的include的关系。如果是这种情况,我怎样才能引用来自用户制作的包含中的where语句的匹配字段,以便我可以比较,例如User.uid和Matches.uid_prop。 我尝试过这种符号,但它没有用:$ Matches.uid_prop $
Matches.findAll({
attributes: ['porcentaje'],
where: {
$or: [
{uid_prop: uid},
{uid_player: uid}
]
},
include: [{
model: User,
attributes: ['uid'],
include: [{
model: Profile_user,
attributes: ['name', 'profile', 'birthday', 'location']
}]
}]
})
答案 0 :(得分:2)
我认为您需要的只是required : true
(内部联接),如:
Matches.findAll({
attributes: ['porcentaje'],
where: {
$or: [
{uid_prop: uid},
{uid_player: uid}
]
},
include: [{
model: User,
attributes: ['uid'],
required : true , //<-------- HERE -------
include: [{
model: Profile_user,
attributes: ['name', 'profile', 'birthday', 'location']
}]
}]
})
您的查询正在进行LEFT JOIN,要使其完全进入INNER JOIN,您可以使用required : true
。
