    I had a similar problem working with MySQL in a Node.js project.

    I found that if you still want to use select * instead of listing out all columns and using an alias, the following works:

    SELECT *, category.id AS cId, category.name AS cName 
    FROM product LEFT JOIN category ON product.category_id = category.id
    

    In other words, just create aliases for the joined columns that have conflicting names. You don't need aliases on other columns or on the table names.
