You don't need to derive anything, sqlx creates structs with the query results for you. The rest of your complaints are just the natural consequence of SQL's design. sqlx is no more difficult to use than similar libraries in other languages.
No.
The structs sqlx creates through the macros are unnameable types, they are created on the fly at the invocation site. This means you can't return them without transforming them into a type you own (you declared), either through the FromRow derive, or writing glue code that associates this unnameable type's fields to your own struct's fields, leading to the boilerplate I was referring to. This is very specific to sqlx, don't try to dilute this into "other libraries are similar".
If you choose to forgo the macros, and use the regular .query() methods, then the results you get are tied to the lifetime of the sqlx connection object, which makes them unergonomic, which is again very specific to sqlx.
