query and update into/using vector

[solarobot]

HI,

I have exactly same problem as below
refer to stackoverflow:
https://stackoverflow.com/questions/42260993/c-soci-query-into-vector-of-custom-object

to select batch of size rows to vector of custom struct.

template<> struct type_conversion
{
typedef values base_type;

static void from_base(const values& v, indicator /* ind */, Event& event)
{
    event.m_id = v.get<std::string>("id");
    event.m_title = v.get<std::string>("Title");
    event.m_description = v.get<std::string>("Description");
    event.m_date = v.get<std::tm>("Date");
}

static void to_base(const Event& event, values& v, indicator& ind)
{
    v.set("id", event.m_id);
    v.set("Title", event.m_title);
    v.set("Description", event.m_description);
    v.set("Date", event.m_date);

    ind = i_ok;
}

};

std::vector<Event*> events;
sql << "SELECT * FROM Event", into(events)

The compilation error below:

Just wonder if this is supported in the latest version or workaround is necessary for this?
BTW, batch update from vector as well.

Appreciate the clarity.
