Is there any use to duplicate column names in a table?

Question

In sqlite3, I can force two columns to alias to the same name, as in the following query:

SELECT field_one AS overloaded_name,
       field_two AS overloaded_nam         


        

Answer 1

The table itself can't have duplicate column names because inserting and updating would be messed up. Which column gets the data?

During selects the "duplicates" are just column labels so do not hurt anything.
