In the previous MongoDB Tutorial<\/strong>, we have discussed How MongoDB create database<\/strong>,\u00a0when we insert the values in a document and save it. We have also created a database with a name \u201cdataflair\u201d.<\/p>\n

In this\u00a0Tutorial, we are going to learn\u00a0How MongoDB Drop Database. Moreover, we will discuss the easy steps to drop database in MongoDB including\u00a0<\/strong>dropDatabase() method.
\nSo, let’s start with MongoDB Drop Database.<\/p>\n

MongoDB Drop Database<\/h2>\n

In MongoDB Drop Database, a command is used to drop the database from it. For this purpose, we can use a dropDatabase command. The user must know that it also deletes the data files associated with it. It operates on the current database or let us say selected database.<\/p>\n

\"MongoDB<\/a>

MongoDB Drop Database<\/p><\/div>\n

a. List the Database<\/h3>\n

First of all, you should execute show dbs command to know if your database exists in MongoDB. For example,<\/p>\n

> show dbs\r\nlocal\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 0.52938GB\r\ndataflair\u00a0\u00a0\u00a0\u00a0   \u00a0 0.49231GB\r\ntest\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 0.49231GB<\/pre>\n
We can see that we had created a database with the name \u201cdataflair\u201d. If your database exists, move to the next step.<\/p>\n
b. Check the Selected Database<\/h3>\n
You should make sure that you have selected the database you have to delete it. Run the db command in the command prompt to know the selected database.<\/p>\n
>db\r\n\u00a0Dataflair<\/pre>\n
In case you have not selected the right database, you should select that.<\/p>\n
c. Select the Database<\/h3>\n
You should execute the \u201cuse\u201d<\/strong> command as previously discussed.<\/p>\n
>use dataflair\r\nSwitched to db dataflair<\/pre>\n
After doing that you can move to the next and final step.<\/p>\n
d. Command for Drop Database<\/h3>\n
Here, \u201cdropDatabase()\u201d command is used for MongoDB drop database. It is executed on the selected database.<\/strong>\u00a0<\/strong><\/p>\n
>db. dropDatabase()\r\n{ \"dropped\": \"dataflair\", \"ok\": 1}<\/pre>\n
It shows that the database has been deleted. You can also confirm by using \u201cshow dbs\u201d<\/strong> command that will enlist the existing databases.
\nSo, this was all\u00a0about MongoDB Drop Database Tutorial. Hope you like our explanation<\/b>.<\/p>\n
Conclusion<\/h2>\n
Hence, we have seen that how easy is that to create and drop the database in the MongoDB. MongoDB drop all database command deletes the data associated with the database which is deleted.<\/p>\n
Moving forward, we will see how to create a collection in MongoDB in the upcoming chapter.\u00a0Furthermore, if you have any query, feel free to ask in the comment section.<\/p>\n","protected":false},"excerpt":{"rendered":"
