Question

I have error when use sqlx with postgresql : "missing destination name rec_created_by"

type Client struct {
    ClientID                    string          `json:"client_id"   db:"id"`
    Name                        string          `json:"name"    db:"name"`
    Version                     int16           `json:"version" db:"version"`
    IsActivated                 bool            `json:"is_activated"    db:"is_activated"`
    RecCreatedBy                string          `json:"rec_created_by"  db:"rec_created_by"`
    RecCreatedByUser            *User           `json:"rec_created_by_user" db:"-"`
    RecCreated                  *time.Time      `json:"rec_created" db:"rec_created"`
    RecModifiedBy               string          `json:"rec_modified_by" db:"rec_modified_by"`
    RecModifiedByUser           *User           `json:"rec_modified_by_user"    db:"-"`
    RecModified                 *time.Time      `json:"rec_modified"    db:"rec_modified"`
    CultureID                   string          `json:"culture_id"  db:"culture_id"`
    ...
}
func (c *Client) Get(id string) error {
    db, err := sqlx.Connect(settings.Settings.Database.DriverName, settings.Settings.GetDbConn())
    if err != nil {
        log.Fatal(err)
    }
    defer db.Close()
    _client := Client{}
    err = db.QueryRowx("SELECT id, name, version, is_activated, rec_created_by, rec_created, rec_modified_by, rec_modified, culture_id, amount_decimal_places, amount_rounding_precision, \"unit-amount_decimal_places\", \"unit-amount_rounding_precision\", currency_lcy_id  FROM client WHERE id=$1", id).StructScan(&_client)
    if err == sql.ErrNoRows {
        return ErrClientNotFound
    } else if err != nil {
        return err
    }
    return nil
 }

I have db:"rec_created_by" in my Client type but why error occurred.
