If there is no name, it will return null\n- The MySQL node will insert the new contact into a table in your database\n- If the contact email already exists in your database, the MySQL node will update the contact name\n\n\n## How to use:\n- Please set up the MySQL node by selecting the correct table to store contacts in\n- Please choose your \"email\" column to match on\n- Please choose your \"name\" column to store names\n"
