In MongoDB, the renameCollection
operation is used to rename an existing collection. This method is essential for reorganizing and managing collection names within MongoDB databases.
db.collection.renameCollection(newName, options)
The renameCollection
method takes a newName
to specify the new name for the collection and an optional options
parameter to customize the renaming process.
Let's look at an example of how to use the renameCollection
method in MongoDB:
db.programGuru.renameCollection("newProgramGuru")
This command renames the programGuru
collection to newProgramGuru
.
Let's go through a complete example that includes switching to a database, creating a collection, inserting documents, and renaming the collection.
This step involves switching to a database named myDatabase
.
use myDatabase
In this example, we switch to the myDatabase
database.
This step involves creating a new collection named programGuru
in the myDatabase
database.
db.createCollection("programGuru")
Here, we create a collection named programGuru
.
This step involves inserting documents into the programGuru
collection.
db.programGuru.insertMany([
{ name: "John Doe", age: 30, email: "john.doe@example.com" },
{ name: "Jane Smith", age: 25, email: "jane.smith@example.com" },
{ name: "Jim Brown", age: 35, email: "jim.brown@example.com" }
])
We insert multiple documents into the programGuru
collection.
This step involves using the renameCollection
method to rename the programGuru
collection to newProgramGuru
.
db.programGuru.renameCollection("newProgramGuru")
We rename the programGuru
collection to newProgramGuru
.
The MongoDB renameCollection
operation is crucial for reorganizing and managing collection names within databases. Understanding how to use this method allows you to efficiently manage and maintain the structure of your MongoDB collections.
