Alias allows you to rename a standard named column to another column
name.  I agree that the commented items are confusing.  However, both of
the uncommented ones are common renames of the standard columns.

No, what this will do is add the static definition of the literal value
"mycolumn" to the mycolumn field.  What you actually want is to add
the field to your table (ALTER TABLE ... ADD COLUMN ...) and add it to
your extensions.conf (and reload).  That's it.  There is literally nothing
you have to change in the cdr_mysql.conf file to add an extra column.  There
is also literally nothing you have to change in the cdr_mysql.conf file to
_delete_ a standard column.  Just have the column not appear in the backend
table (ALTER TABLE ... DROP COLUMN ...) and reload Asterisk.  The "static"
definition is for implicit values only.  The "alias" column is just for
renaming standard columns.
