如何通过命令行连接到我的MongoDB表?
db.yourCollectionName.find();
假设我们有一个带有一些集合的数据库“样本”。首先检查当前数据库
> use sample;switched to db sample
> db;
Sample
Now we have reached the database sample. The database “sample” is having the following collections:
> show collections;
这将产生以下输出

copyThisCollectionToSampleDatabaseDemo

deleteDocuments

userInformation
这是连接到表(即集合)的正确方法。您需要使用db命令。以下是查询
> db.userInformation.find();
这将产生以下输出
{ "_id" : ObjectId("5c6a765964f3d70fcc9147f5"), "Name" : "John", "Age" : 30, "isStudent" : false, "Subjects" : [ "Introduction to java", "Introduction to MongoDB" ] }
