MySQL naming conventions, should field name include the table name?

Question

A friend told me that I should include the table name in the field name of the same table, and I\'m wondering why? And should it be like this? Example:

(Table)         


        

Answer 1

Sounds like the conclusion is: If the field name is unique across tables - prefix with table name. If the field name has the potential to be duplicated in other tables, name it unique.

I found field names such as "img, address, phone, year" since different tables may include different images, addresses, phone numbers, and years.
