To connect to MySQL from the command line, follow these steps:

  1. Log in to your A2 Hosting account using SSH.
  2. At the command line, type the following command, replacing USERNAME with your username:
    mysql -u USERNAME -p
  3. At the Enter Password prompt, type your password. When you type the correct password, the mysql> prompt appears.
  4. To display a list of databases, type the following command at the mysql> prompt:

    show databases;
  5. To access a specific database, type the following command at the mysql> prompt, replacing DBNAME with the database that you want to access:

    use DBNAME;
  6. After you access a database, you can run SQL queries, list tables, and so on. Additionally:

    • To view a list of MySQL commands, type help at the mysql> prompt.
    • To exit the mysql program, type \q at the mysql> prompt.

    When you run a command at the mysql> prompt, you may receive a warning message if MySQL encounters a problem. For example, you may run a query and receive a message that resembles the following:

    Query OK, 0 rows affected, 1 warning (0.04 sec).
