Golang data mapping library for postgres and pgx

I like the (very) lean premise of pmx
, since it enables us to avoid bloated ORMs.
However, the fact that for e.g. an pmx.Update
query there is no return value that enables us to see whether there was in fact an update (i.e. "RowsAffected") is problematic, since usually one would like to make this distinction (additionally to error/no-error).
So it would be better to have either (always/optionally?) commandTag
returned, or have an additional Update
wrapper that can be chosen to get more feedback.
https://www.postgresql.org/docs/current/sql-insert.html#SQL-ON-CONFLICT
Instead of relying on duplicate key errors I'd like to use ON CONFLICT DO NOTHING and CommandTag.RowsAffected().
Also, as Update() seems to be removed (I'm currently on v0.0.0-20230325043427-5b6ceb086444) DO UPDATE would probably be also useful.
type B struct {
Type string `db:"type" table:"games_bets"`
Game Game `db:"" table:"games"`
User storusermodel.User `db:"" table:"users"`
Amount float64 `db:"amount"`
Value string `db:"value"`
}
I have this struct, how i can scan into Game and User?
If I'm calling Insert and passing a struct is it possible to get it to return with the autogenerated fields filled in?
type Request struct {
ID uuid.UUID `json:"-" generated:"auto" db:"id" table:"sign_request_user"`
Request string `json:"request" db:"request"`
Created time.Time `json:"-" generated:"auto" db:"-"`
Updated time.Time `json:"-" generated:"auto" db:"-"`
Status string `json:"-" generated:"auto" db:"-"`
So I insert just the Request value into the struct and would get back filled in ID, Status and such.
Hi, I've stumbled over your library while searching for how to use the pgx struct tags with insert / update operations. In my opinion the pgx functionality is quite incomplete because it only allows for scanning. Don't you think it would be a better idea to try to upstream the functionality of your library to the pgx project?
