MongoDB CRUD之C

.unicorns.insertMany([ { name: 'Horny', dob: new Date(1992,2,13,7,47), loves: ['carrot','papaya'], weight: 600, gender: 'm', vampires: 63}, { name: 'Aurora', dob: new Date(1991, 0, 24, 13, 0), loves: ['carrot', 'grape'], weight: 450, gender: 'f', vampires: 43}, { name: 'Unicrom', dob: new Date(1973, 1, 9, 22, 10), loves: ['energon', 'redbull'], weight: 984, gender: 'm', vampires: 182}, { name: 'Roooooodles', dob: new Date(1979, 7, 18, 18, 44), loves: ['apple'], weight: 575, gender: 'm', vampires: 99}, { name: 'Solnara', dob: new Date(1985, 6, 4, 2, 1), loves:['apple', 'carrot', 'chocolate'], weight:550, gender:'f', vampires:80}, { name:'Ayna', dob: new Date(1998, 2, 7, 8, 30), loves: ['strawberry', 'lemon'], weight: 733, gender: 'f', vampires: 40}, { name:'Kenny', dob: new Date(1997, 6, 1, 10, 42), loves: ['grape', 'lemon'], weight: 690, gender: 'm', vampires: 39}, { name: 'Raleigh', dob: new Date(2005, 4, 3, 0, 57), loves: ['apple', 'sugar'], weight: 421, gender: 'm', vampires: 2}, { name: 'Leia', dob: new Date(2001, 9, 8, 14, 53), loves: ['apple', 'watermelon'], weight: 601, gender: 'f', vampires: 33}, { name: 'Pilot', dob: new Date(1997, 2, 1, 5, 3), loves: ['apple', 'watermelon'], weight: 650, gender: 'm', vampires: 54}, { name: 'Nimue', dob: new Date(1999, 11, 20, 16, 15), loves: ['grape', 'carrot'], weight: 540, gender: 'f'}, { name: 'Dunx', dob: new Date(1976, 6, 18, 18, 18), loves: ['grape', 'watermelon'], weight: 704, gender: 'm', vampires: 165} ])

Mongo shell使用load("insertM.js")

19 > load("insertM.js")
true
20 > db.unicorns.find()
{ ..., "name" : "Aurora", "gender" : "f", "weight" : 450 }
{ ..., "name" : "Horny", "dob" : ISODate("1992-03-12T23:47:00Z"), ...}
{ ..., "name" : "Aurora", "dob" : ISODate("1991-01-24T05:00:00Z"), ... }
......
21 > db.unicorns.count()
13

可以看到插入了13条数据

插入多条或者一条数据使用insert

• 插入一条时语法与insertOne一样
• 插入多条时语法与insertMany一样

循环插入多条数据

22 > for(i = 3; i < 100;  i ++)db.set2test.insert({x:i})
WriteResult({ "nInserted" : 1 })
23 > db.set2test.count()
97

可以看到使用了循环插入并创建集合 set2test ,插入完成后集合中有了97条数据
