以下代码/命令可直接复制粘贴

第一关 数据库创建

pgrep mongo -l
mongo
use mydb
db.mydb.insert({_id:1,name:"李小红"})

第二关 创建集合

mongo
use Testdb2
db.t_stu.insert([{"_id":1,"name" : "小明","sex":"男","hobbies":["乒乓球","羽毛球"]},{"_id":2,"name" : "小红","sex":"女","hobbies":["画画","唱歌"]}])

第三关 文档操作一

mongo
use Testdb3
document=({_id:1,
    name: '张小华',
    sex: '男',
    phone: '12356986594',
    hobbies: ['打篮球','踢足球','唱歌']
});
db.stu1.insert(document)
db.stu2.insert(document)
db.stu3.insert(document)

db.stu2.update({phone:"12356986594"},{$set:{phone:"18356971462"}})
db.stu3.save({
    "_id" :1,
    "name" : "张晓晓",
    "sex" : "女",
    "phone" : "12365498704",
    "hobbies" : [
            "跳舞",
            "羽毛球",
            "唱歌"
    ]
})
