How to delete table in MySQL or MariaDB

Deleting tables in databases is a critical operation, as it results in a permanent loss of data. In the MySQL and MariaDB relational database systems, this operation is common and straightforward, yet must be approached with caution.

Both MySQL and MariaDB are descendants of the original MySQL database project. Consequently, the steps for various operations, including table deletion, are largely identical in both database systems. If you're uncertain about whether you need the table later, always consider backing up your data before the deletion.

In this guide, we'll walk through the steps required to delete a table in a MySQL or MariaDB database. These instructions are intended for individuals with some prior knowledge of using SQL databases and are familiar with the risks associated with deleting tables.

1. Launch the terminal or your preferred database interface tool.
2. Connect to the MySQL or MariaDB server using the mysql command.

   $ mysql -u username -p
     - Enter password:

3. Select the desired database.

   mysql> USE database_name;

   Make sure you select the correct database to prevent deleting tables from an unintended database.

4. Confirm the list of tables in the database.

   mysql> SHOW TABLES;

5. Delete the desired table.

   mysql> DROP TABLE table_name;

   Be cautious! This action will permanently delete the table and all of its data. Ensure you have backups if needed.

6. Confirm the table's deletion by trying to display its content.

   mysql> SELECT * FROM table_name;

   If the table was deleted successfully, you should receive an error stating that the table doesn't exist.

7. Exit the database interface.

   mysql> EXIT;

Remember, always handle database operations with care, especially when deleting tables or data. Regular backups can prevent significant data loss and ensure that you can restore any crucial data if mistakes happen.
