如果您想列出特定数据库中的所有集合，则需要先切换数据库。查询语句如下:
> use sample; switched to db sample > db.getCollectionNames();
以下是输出 −
[ "copyThisCollectionToSampleDatabaseDemo", "deleteDocuments", "deleteDocumentsDemo", "deleteInformation", "employee", "internalArraySizeDemo", "sourceCollection", "updateInformation", "userInformation" ]
另一种查询方式如下 −
> show collections;
以下是输出 −
copyThisCollectionToSampleDatabaseDemo deleteDocuments deleteDocumentsDemo deleteInformation employee internalArraySizeDemo sourceCollection updateInformation userInformation
