Export Data

  1. Determine the connection parameters for your MariaDB SkySQL service.

  2. Use MariaDB Client with the connection information to export your schema from your MariaDB SkySQL database service:

    $ mariadb --host FULLY_QUALIFIED_DOMAIN_NAME --port TCP_PORT \
      --user DATABASE_USER --password \
      --ssl-verify-server-cert \
      --ssl-ca ~/PATH_TO_PEM_FILE \
      --default-character-set=utf8 \
      --batch \
      --skip-column-names \
      --execute='SELECT * FROM accounts.contacts;' \
      > contacts.tsv

    • Replace FULLY_QUALIFIED_DOMAIN_NAME with the Fully Qualified Domain Name of your service.

    • Replace TCP_PORT with the read-write or read-only port of your service.

    • Replace DATABASE_USER with the default username for your service, or the username you created.

    • Replace ~/PATH_TO_PEM_FILE with the path to the certificate authority chain (.pem) file.

    • Optionally, for large tables, specify the --quick command-line option to disable result caching and reduce memory usage.

  3. After the command is executed, you will be prompted for a password. Enter the default password for your default user, the password you set for the default user, or the password for the database user you created.
