If you use the ResNSel object you can check whether or not the query
succeeded AND how many rows were affected:
(note: from memory, details may not be quite right)
mysqlpp::Query q = conn.query();
q << <update of some sort>;
mysqlpp::ResNSel res = q.execute();
if (!res || res.rows < 1) {
// query failed
}
