Trying to generate a list of tracks composed by more than one person.
Name Composer Make
Name composer Make
Going home Robert dennings / Don Bedge Robert dennings , Don Bedge
You probably want something like this
SELECT Name, Composer, REPLACE(Composer,'/',',') AS Make FROM tracks
But it really is impossible to tell for sure given that you don't tell us any of the table or field names in your database and very little about your database model
