通过Java从Postgresql获取RETURNING值

通过Java从Postgresql获取RETURNING值

根据javadoc，PreparedStatement继承自Statement，后者包含getResultSet（）方法。换句话说，请尝试以下 *** 作：

String insertStatement = "INSERT INTO person(n" +     " name, address, phone, customer_type, n" +     " start_dtm)n" +     "    VALUES (?, ?, ?, ?, n" +     " ?)n" +     "    RETURNING person_id;";PreparedStatement stmt = connection.prepareStatement(insertStatement);stmt.setObject(1, perToSave.getName(null));stmt.setObject(2, editToSave.getAddress());stmt.setObject(3, editToSave.getPhone());stmt.setObject(4, editToSave.getCustType());long epochTime = java.lang.System.currentTimeMillis();stmt.setObject(5, new java.sql.Date(epochTime));stmt.executeUpdate();ResultSet last_updated_person = stmt.getResultSet();last_updated_person.next();int last_updated_person_id = last_updated_person.getInt(1);
