If I understand correctly, you are trying to grep the SQL data file. This
is emphatically not a valid thing to do. The data file is *not* a
representation of the table displayed when you SELECT * from it. For a
start, if you have deleted records and not overwritten them, the blank

As I read the manual, the REPLACE command will do what you want.
Make the name field UNIQUE, and the number field AUTO_INCREMENT NOT NULL.
Replace dos a delete-if-present, insert. The insert generates a new ID.
