Change collection name in MongoDB?
Use use renameCollection() to change collection name in MongoDB. Following is the syntax
db.yourOldCollectionName.renameCollection("yourNewCollectionName");Let us create a collection with documents. Following is the query
> db.savingInformationDemo.insertOne({"StudentName":"Larry"});
{
"acknowledged" : true,
"insertedId" : ObjectId("5c9cb44da629b87623db1b07")
}
> db.savingInformationDemo.insertOne({"StudentName":"John"});
{
"acknowledged" : true,
"insertedId" : ObjectId("5c9cb45da629b87623db1b08")
}
> db.savingInformationDemo.insertOne({"StudentName":"Mike"});
{
"acknowledged" : true,
"insertedId" : ObjectId("5c9cb461a629b87623db1b09")
}
> db.savingInformationDemo.insertOne({"StudentName":"Sam"});
{
"acknowledged" : true,
"insertedId" : ObjectId("5c9cb465a629b87623db1b0a")
}Following is the query to display all documents from a collection with the help of find() method
> db.savingInformationDemo.find().pretty();
This will produce the following output
{ "_id" : ObjectId("5c9cb44da629b87623db1b07"), "StudentName" : "Larry" }
{ "_id" : ObjectId("5c9cb45da629b87623db1b08"), "StudentName" : "John" }
{ "_id" : ObjectId("5c9cb461a629b87623db1b09"), "StudentName" : "Mike" }
{ "_id" : ObjectId("5c9cb465a629b87623db1b0a"), "StudentName" : "Sam" }Following is the query to change collection name in MongoDB
> db.savingInformationDemo.renameCollection("saveStudentInformation");This will produce the following output
{ "ok" : 1 }Following is the query to check the documents are displayed with new collection name or not
> db.saveStudentInformation.find();
This will produce the following output
{ "_id" : ObjectId("5c9cb44da629b87623db1b07"), "StudentName" : "Larry" }
{ "_id" : ObjectId("5c9cb45da629b87623db1b08"), "StudentName" : "John" }
{ "_id" : ObjectId("5c9cb461a629b87623db1b09"), "StudentName" : "Mike" }
{ "_id" : ObjectId("5c9cb465a629b87623db1b0a"), "StudentName" : "Sam" }
