从sphinx db到有点复杂的golang结构的最佳实践

I am trying to convert a sphinx query via MySQL into a golang struct and am having a hard time. It seems like this should be a common sort of problem, but so far I'm stuck converting it to a map or parsing output myself. Specifically, I have a schema in sphinx that looks like {Source: {ID:string, subId:string, Campaigns:[]{CampaignID:string, Status:string}}}

I've tried using the simple rows.scan but that doesn't help me parse the repeating field, I just get it as an unparsed string. In sphinx, the key's aren't in quotation marks, so JSON.unmarshal doesn't seem to help at all. And using sqlx, I've tried to build up the following struct

type CampaignStatus struct {
    CampaignId string
    Status string
}
type Source struct {
    Id               string
    SubId    string
    StatusByCampaign []CampaignStatus
}
type Status struct {
    Source
}

and passing in a Status struct to Row.ScanStruct() and I get back either a "Missing destination Name Source" error or if I name the source member in Status, I get "sql: Scan error on column index 0: unsupported Scan, storing driver.Value type []uint8 into type *v1.Source". Full disclosure, the sphinx schema has a few other columns as peers with StatusByCampaign, they come after it and I don't care about them in my use case.

This seems like something that has to have been come across before, but I can't seem to find a solution outside of writing my own parser, which I am loath to do.
