[Advice] Chaining and Queries

[euca01]

Hi :),

I would like to chain a query though function. For example, i've :

err := db.Select("name").
    From("users").
    Where(dbx.HashExp{"UserId": 1}).
    One(&user)

And i would like to have something like that :

func ScopeByUserId( uID int ) {
    return Where(dbx.HashExp{"UserId": 1})
}

err := db.Select("name").
    From("users").
    ScopeByUserId( uID int ) .
    One(&user)

The idea is to be able to reuse the code. Is there a best pratice or advices for doing it ?

Thanks a lot for your help :)
