Isn't SQLites datetime data type affinity to NUMERIC anyway?

Ive slightly simplified the SQL query in my original email, but here is
the whole function.
cppdb::result Base::get_all_items(unsigned int aircraft_id, const Table&
tbl, int date_limited_only)
{
cppdb::result r;
//std::tm ts = dt_to_time(session_timestamp());
string ts = "2012-05-17 23:59:59";
ostringstream os;
os << "SELECT i.id, i.name, i.remarks, i.part_number, h1.id AS rev_id, ";
os << tbl.column_string("h1") << " ";
os << "FROM " << tbl.name() << "s i ";
os << "INNER JOIN " << tbl.name() << "s_history h1 ON h1.root_id=i.id ";
os << "AND h1.days >= ? AND h1.date_fitted <= ? AND (h1.disabled_at IS
NULL OR h1.disabled_at > ?) ";
os << "AND h1.id IN (SELECT max(h2.id) FROM " << tbl.name() <<
"s_history h2 WHERE h2.date_fitted <= ? AND h2.root_id=i.id)";
os << "WHERE h1.aircraft_id = ? ORDER BY i.id ASC";
r = sql << os.str()
<< date_limited_only
<< ts
<< ts
<< ts
<< aircraft_id;
return r;
}
