Question

我已经使用cakephp Mysql来Mongo db查询组件，即修改mysql查询进入mongodb，但是当查询有多个括号时代码已经停止工作，我也尝试在http://www.querymongo.com/网站上转换查询同样的问题出现，

SELECT * FROM `matches` WHERE (
( user_id = "550aa8b6156b046c09000000" AND partner_user_id = "55094c30156b049809000004" ) OR
( user_id = "55094c30156b049809000004" AND partner_user_id = "550aa8b6156b046c09000000" ) OR 
( doublz_partner_id_a = "55094c30156b049809000004" AND doublz_partner_id_b = "550aa8b6156b046c09000000" ) OR 
( doublz_partner_id_a = "550aa8b6156b046c09000000" AND doublz_partner_id_b = "55094c30156b049809000004" ) 
)

你可以帮我把这个问题转换成mogodb，我是mongodb的新手

恭喜您不遗余力地查看文档并解决此问题。也许你的“网站”也应该做得更好：

db.matches.find({
    "$or": [
        { 
            "user_id": "550aa8b6156b046c09000000", 
            "partner_id": "55094c30156b049809000004" 
        },
        { 
            "user_id": "55094c30156b049809000004", 
            "partner_id": "550aa8b6156b046c09000000" 
        },
        { 
            "doublz_partner_id_a": "55094c30156b049809000004", 
            "doublz_partner_id_b": "550aa8b6156b046c09000000" 
        },
        { 
            "doublz_partner_id_a": "550aa8b6156b046c09000000", 
            "doublz_partner_id_b": "55094c30156b049809000004" 
        }
    ]
})

如您在文档中所述构建$or查询的方式。

顺便说一句，“谢谢你帮助我”是你的回应。

db.matches.find({"$or": [
        { 
            "user_id" : "550aa8b6156b046c09000000", 
            "partner_id" : "55094c30156b049809000004" 
        },
        { 
            "user_id" : "55094c30156b049809000004", 
            "partner_id": "550aa8b6156b046c09000000" 
        },
        { 
            "doublz_partner_id_a" : "55094c30156b049809000004", 
            "doublz_partner_id_b" : "550aa8b6156b046c09000000" 
        },
        { 
            "doublz_partner_id_a" : "550aa8b6156b046c09000000", 
            "doublz_partner_id_b" : "55094c30156b049809000004" 
        }
    ]
})
