要在MongoDB中重命名集合，可以使用renameCollection()方法。语法如下-
db.yourOldCollectionName.renameCollection('yourNewCollectionName');为了理解上述语法，让我们列出数据库样本中的所有集合。查询如下-
> use sample; switched to db sample > show collections;
以下是输出-
copyThisCollectionToSampleDatabaseDemo deleteDocuments deleteDocumentsDemo employee informationAboutDelete internalArraySizeDemo prettyDemo selectWhereInDemo sourceCollection updateInformation userInformation
现在，将集合名称“ informationAboutDelete”更改为“ deleteSomeInformation”。查询如下以更改集合名称。
> db.informationAboutDelete.renameCollection('deleteSomeInformation');
{ "ok" : 1 }这是查询以检查集合名称已重命名为'deleteSomeInformation'-
> show collections;
以下是输出-
copyThisCollectionToSampleDatabaseDemo deleteDocuments deleteDocumentsDemo deleteSomeInformation employee internalArraySizeDemo prettyDemo selectWhereInDemo sourceCollection updateInformation userInformation
