Mongodb常用命令

最近经常用到mongodb，现把常用命令汇总如下：

1、创建集合

db.createCollection("modb_test")

2、复制集合（同库复制）

1 db.modb_test.find().forEach(function(x){db.modb_test2.insert(x)})

3、删除集合

1 db.modb_test2.drop()

4、查看一条

 1 db.modb_test.findOne()

30                     "role_list" : [
31                         "5cda9e25ac91bb0001e3d584"
32                     ],
33                     "pro_id" : "55439bed-de5a-4539-bee8-33c7ee97a7cc"
34                 }
35             ],

49         }
50     ],
51     "email" : "[email protected]"
52 }

7、删除site_info中site_id为casdfweradc2238db9adbdcd的数据

1 db.modb_test.update({"_id":"5cda9deeac91bb0001e3d582"},{$pull:{"site_info":{"site_id":"casdfweradc2238db9adbdcd"}}})

8、只列出site_info中site_id为5cc02b9e0726b7066e0d420b的节点数据

 1 db.modb_test.find({"_id":"5cda9deeac91bb0001e3d582"},{"site_info":{$elemMatch:{"site_id":"5cc02b9e0726b7066e0d420b"}}})

 3 查询结果
 4 {
 5     "_id" : "5cda9deeac91bb0001e3d582",
 6     "site_info" : [
 7         {
 8             "pro_list" : [
 9                 {
10                     "role_list" : [
11                         "5cda9e25ac91bb0001e3d584"
12                     ],
13                     "pro_id" : "9cced61a0726b762781b199e"
14                 },
15                 {
16                     "role_list" : [
17                         "5cda9e25ac91bb0001e3d584"
18                     ],
19                     "pro_id" : "76faada2-3381-450c-bca4-4527b44a5b76"
20                 },
21                 {
22                     "role_list" : [
23                         "5cda9e25ac91bb0001e3d584"
24                     ],
25                     "pro_id" : "55439bed-de5a-4539-bee8-33c7ee97a7cc"
26                 }
27             ],
28             "sys_role_id" : "5cda9e1aac91bb0001e3d583",
29             "site_id" : "5cc02b9e0726b7066e0d420b",
30             "company_type" : null,
31             "global_project_role_id" : "5cda9e36ac91bb0001e3d585",
32             "belong" : "2",
33             "company_id" : "5c67e745-618e-4e76-9202-b692c345c940",
34             "office_id" : "",
35             "is_valid" : 0,
36             "max_pro_num" : 33,
37             "join_pro_num" : 0
38         }
39     ]
40 }

9、内嵌节点操作,用点做连接操作符

1 db.modb_test.find("site_info.pro_list.pro_id":"9cced61a0726b762781b199e")

10、按条件查询对应数据，然后往site_info中的pro_list中插入数据

 1 db.modb_test.update({"_id":"5cda9deeac91bb0001e3d582","site_info.site_id":"5cc02b9e0726b7066e0d420b"},{$push:{"site_info.$.pro_list":{"role_list":[],"pro_id":"12387123261a0726b762781b199e"}}})
