mysql数据库使用mybatis 插入数据时返回主键

为了体现题目，特指的是mysql，先贴上代码：

  <insert id="saveBizProdOrderDetail" useGeneratedKeys="true" keyProperty="id" parameterType="com.xxx.insurance.entity.BizProdOrderDetail" >
    insert into biz_prod_order_detail (ORDERCODE, PRODCODE, COUNT, OPTDATE, OPTUSER )
    values ( #{ordercode}, #{prodcode},   #{count}, now(), #{optuser} )
  </insert>
