如何通过命令行连接到我的MongoDB表？
为了通过命令行连接到我的表，您需要使用db命令
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
arraySizeErrorDemo basicInformationDemo copyThisCollectionToSampleDatabaseDemo deleteAllRecordsDemo deleteDocuments deleteDocumentsDemo deleteSomeInformation documentWithAParticularFieldValueDemo employee findListOfIdsDemo findSubstring getAllRecordsFromSourceCollectionDemo getElementWithMaxIdDemo internalArraySizeDemo largestDocumentDemo makingStudentInformationClone oppositeAddToSetDemo prettyDemo returnOnlyUniqueValuesDemo selectWhereInDemo sourceCollection studentInformation sumOfValueDemo sumTwoFieldsDemo truncateDemo updateInformation 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" ] }
