imported table shows id column but none there

[Fran Lee]

I just imported a CSV file into my small MySQL database.

The CSV file had two comma seperated values per line... username and password.

It seemed to have imported OK but when I look at the new tables columns with MySQL Workbench I see 3-columns...
id, username, password

BUT when I query the table...

SELECT id, usernamme, password FROM mydb.users;

Workbench tells me there is no id field.

And I see no id column with this query

SELECT * FROM mydb.users.

Question 1: Did I import the data correctly?
Question 2: Why does Workbench show me an id column when apparently there isn't one?
Question 3: Should I do it over differently?

Thanks for any help.
