比如这样
{ "_id": 1, "array": [ {"name": "a", "price": "2","amount":1}, {"name": "b", "price": "2","amount":2}, {"name": "c", "price": "3","amount":4} ] }
我只想把name属性和price属性导出，该怎么做呢？用mongoexport貌似无法实现啊，诸位有什么好的办法吗？求教了
小伙看你根骨奇佳，潜力无限，来学PHP伐。
mongo supports js scripts, and you can use javascript scripts to batch process and export data:
#!/usr/bin/env mongo db = db.getSiblingDB(db_name) // db.auth("user", "passwd"); result = {}; db.clt_name.find().forEach(function(r) { // 这里是回调函数，r就是每一条记录，是一个object对象，可以遍历r.array，把需要的属性存入result }) for (var key in result) { // 按照你希望的格式输出： print(key + "\t" + result[key]) }
