drop mongo database

To drop a MongoDB database using the Go language, you can follow these steps:

1. Import the necessary packages:

import (
    "context"
    "go.mongodb.org/mongo-driver/mongo"
    "go.mongodb.org/mongo-driver/mongo/options"
)

1. Establish a connection to the MongoDB server:

clientOptions := options.Client().ApplyURI("mongodb://localhost:27017")
client, err := mongo.Connect(context.TODO(), clientOptions)
if err != nil {
    log.Fatal(err)
}

1. Access the database you want to drop:

db := client.Database("your_database_name")

1. Drop the database:

err = db.Drop(context.TODO())
if err != nil {
    log.Fatal(err)
}

1. Close the connection to the MongoDB server:

err = client.Disconnect(context.TODO())
if err != nil {
    log.Fatal(err)
}

Each step is explained briefly below:

1. Import the necessary packages: This step imports the required packages for connecting to MongoDB and performing database operations in Go.

2. Establish a connection to the MongoDB server: This step creates a client connection to the MongoDB server using the provided URI.

3. Access the database you want to drop: This step retrieves a reference to the database you want to drop by specifying its name.

4. Drop the database: This step drops the specified database using the Drop method. It returns an error if the operation fails.

5. Close the connection to the MongoDB server: This step closes the connection to the MongoDB server using the Disconnect method. It is important to close the connection to release resources properly.

Please note that this code assumes you have already installed the necessary Go packages and have a running MongoDB server on your local machine.
