 returned. In this case, `GetInfoForAuthor` returns a struct with two fields:
 `Bio` and `BirthYear`.
 
+If a query result has no row records, a zero value and an `ErrNoRows` error are
+returned instead of a zero value and `nil`. For instance, when the `GetBioForAuthor`
+result has no rows, it will return `""` and `ErrNoRows`.
