To connect to MariaDB on Debian 12 and create a table, you can follow these steps:

1. Install MariaDB:

   sudo apt update
   sudo apt install mariadb-server
   

2. Start the MariaDB service:

   sudo systemctl start mariadb
   

3. Secure the MariaDB installation:

   sudo mysql_secure_installation
   

   This command will prompt you to set a root password and perform other security-related configurations.

4. Connect to the MariaDB server:

   sudo mysql -u root -p
   

   Enter the root password you set during the secure installation.

5. Create a new database:

   CREATE DATABASE your_database_name;
   

   Replace your_database_name with the desired name for your database.

6. Use the newly created database:

   USE your_database_name;
   

7. Create a table:

   CREATE TABLE your_table_name (
       column1 datatype constraint,
       column2 datatype constraint,
       ...
   );
   

   Replace your_table_name with the desired name for your table. Specify the columns and their datatypes as needed.

8. Insert data into the table:

   INSERT INTO your_table_name (column1, column2, ...)
   VALUES (value1, value2, ...);
   

   Replace your_table_name with the name of your table. Specify the values to be inserted into the respective columns.

That’s it! You have now connected to MariaDB on Debian 12 and created a table.
