How to Join Two Tables with jmoiron/sqlx

Here's an example of how to define relationships between structs when using SQL joins and sqlx: ```go type Feed struct { ID int `json:"id"` Title string `json:"title"` URL string `json:"url"` CreatedAt time.Time `json:"created_at" db:"created_at"` } type FeedItem struct { ID int `json:"id"` Title string `json:"title"` Description sql.NullString `json:"description"` URL string `json:"url"` CreatedAt time.Time `json:"created_at" db:"created_at"` FeedId int `json:"feed_id" db:"feed_id"` Feed `db:"feed"` // << NOTE PREFIX } func getFeeds() (*[]Feed, error) { feeds := []Feed{} err := db.Select(&feeds, "SELECT * FROM feeds") return &feeds, err } func getFeedItems() (*[]FeedItem, error) { items := []FeedItem{} sql := `SELECT feed_items.*, feeds.id "feed.id", feeds.title "feed.title", feeds.url "feed.url", feeds.created_at "feed.created_at" FROM feed_items JOIN feeds ON feed_items.feed_id = feeds.id;` err := db.Select(&items, sql) return &items, err } ```
