集合中的数据如下:
{ title: 'MongoDB Overview', description: 'MongoDB is no sql database', by_user: 'runoob.com', url: 'http://www.runoob.com', tags: ['mongodb', 'database', 'NoSQL'], likes: 100 }, { title: 'NoSQL Overview', description: 'No sql database is very fast', by_user: 'runoob.com', url: 'http://www.runoob.com', tags: ['mongodb', 'database', 'NoSQL'], likes: 10 }, { title: 'Neo4j Overview', description: 'Neo4j is no sql database', by_user: 'Neo4j', url: 'http://www.neo4j.com', tags: ['neo4j', 'database', 'NoSQL'], likes: 750 },
如果使用如下操作,只会插入第一条数据
db.col.insert(
{
"title": 'MongoDB Overview',
"description": 'MongoDB is no sql database',
"by_user": 'runoob.com',
"url": 'http://www.runoob.com',
"tags": ['mongodb', 'database', 'NoSQL'],
"likes": 100
},
{
"title": 'MongoDB Overview',
"description": 'No sql database is very fast',
"by_user": 'runoob.com',
"url": 'http://www.runoob.com',
"tags": ['mongodb', 'database', 'NoSQL'],
"likes": 10
},
{
"title": 'Neo4j Overview',
"description": 'Neo4j is no sql database',
"by_user": 'runoob.com',
"url": 'http://www.runoob.com',
"tags": ['neo4j', 'database', 'NoSQL'],
"likes": 750
}
)
如果一次性插入多条的话,应该如下:
db.col.insert(
[
{
"title": 'MongoDB Overview',
"description": 'MongoDB is no sql database',
"by_user": 'runoob.com',
"url": 'http://www.runoob.com',
"tags": ['mongodb', 'database', 'NoSQL'],
"likes": 100
},
{
"title": 'MongoDB Overview',
"description": 'No sql database is very fast',
"by_user": 'runoob.com',
"url": 'http://www.runoob.com',
"tags": ['mongodb', 'database', 'NoSQL'],
"likes": 10
},
{
"title": 'Neo4j Overview',
"description": 'Neo4j is no sql database',
"by_user": 'runoob.com',
"url": 'http://www.runoob.com',
"tags": ['neo4j', 'database', 'NoSQL'],
"likes": 750
}]
)
