To rename a collection in MongoDB, you can use renameCollection() method. The syntax is as follows −
db.yourOldCollectionName.renameCollection('yourNewCollectionName');To understand the above syntax, let us list all the collections from database sample. The query is as follows −
> use sample; switched to db sample > show collections;
The following is the output −
copyThisCollectionToSampleDatabaseDemo deleteDocuments deleteDocumentsDemo employee informationAboutDelete internalArraySizeDemo prettyDemo selectWhereInDemo sourceCollection updateInformation userInformation
Now change collection name ‘informationAboutDelete’ to ‘deleteSomeInformation’. The query is as follows to change the collection name.
> db.informationAboutDelete.renameCollection('deleteSomeInformation');
{ "ok" : 1 }Here is the query to check the collection name has been renamed to 'deleteSomeInformation' −
> show collections;
The following is the output −
copyThisCollectionToSampleDatabaseDemo deleteDocuments deleteDocumentsDemo deleteSomeInformation employee internalArraySizeDemo prettyDemo selectWhereInDemo sourceCollection updateInformation userInformation
