The Series of MySQL -4- MySQL User Management - EP 04_04

HI Hi, Greetings!  i_f47.gif

Happy February i_f25.gif

Hi Everyone,

Today, I would like to share with you an article about the fourth episode of Series of MySQL (MySQL Database), and the content is given below.


a.    Create Database

b.   Select Database

c.    Show Databases

d.   Drop Database

e.    Copy Database 


Drop Database

With the MySQL DROP DATABASE command, we may rapidly drop/delete/remove a MySQL database. It will permanently remove the database, including all tables, indexes, and constraints. As a result, we must exercise extreme caution while deleting a database with MySQL, as we will lose all of the database's contents. The DROP DATABASE statement returns an error if the database is not available on the MySQL server.


A database can be dropped, deleted, or removed in MySQL in one of two ways:

·        MySQL Command Line Client

·        MySQL Workbench


MySQL Command Line Client


In MySQL, we can delete an existing database by executing the DROP DATABASE statement, which has the following syntax:


DROP DATABASE [IF EXISTS] database_name;    


For removing a database in MySQL, we can use the syntax below. Because the schema is a synonym for the database, we can interchange the two terms.


DROP SCHEMA [IF EXISTS] database_name;  


The following are the parameter descriptions for the above syntax:

·       database_name

It's the name of an existing database on the server that we wish to remove. In the MySQL server instance, it should be unique.

·        IF EXISTS

It's a choice. It prevents an error from occurring when uninstalling a database that does not exist.




With the help of an example, let's learn how to drop a database in MySQL. If we set the password during installation, open the MySQL console and write it down. We are now prepared to delete a database.


Next, use the "SHOW DATABASES" query to see all of the server's databases:




Let's say we wish to delete the database "empdb1". Execute the following command:




By running the following query, we can see if our database has been destroyed or not. It will seem as follows:




We can see from the above that the database "empdb1" has been successfully erased.



MySQL Workbench (Used to DROP a database).


To utilize this tool to dump a database, we must first open the MySQL Workbench and log in with the MySQL server's username and password. The following screen will appear:




Execute the following steps to delete the database:


Select the Schema menu from the Navigation tab. We can view all of the databases that have been built previously in this section. If you want to delete a database, right-click it under the Schema menu, for example, "empdb1", and pick Drop Schema from the menu, as shown in the following screen.





MySQL Workbench presents a popup box to confirm the deletion process when we select Drop Schema. If we choose Review SQL, the SQL query that will be run will be generated. If we select the Drop Now option, the database will be permanently erased.




It is necessary to select the Review SQL option if we want to delete the database safely. Once we're certain, click the Execute button to put the statement into action. The screen below describes it in greater detail:




MySQL will return the following message once we click the execute button, indicating that the database has been successfully discarded. The number of affected rows is zero because the database "empdb1" is an empty database.




When we look at the schemas tab, we notice that the "empdb1" database is no longer listed.
