mybatis中批量插入与批量更新

批量插入:

<insert id="insertBatch" parameterType="java.util.List">
   insert into order_promotion_details (pmt_id, promotion_name, promotion_fee, 
      promotion_desc, promotion_id, gift_item_id, 
      gift_item_name, gift_item_num, pmt_type, 
      update_time, create_time)
    values 
     <foreach collection="list" item="item" index="index" separator="," >
    (#{item.pmtId,jdbcType=VARCHAR}, #{item.promotionName,jdbcType=VARCHAR}, #{item.promotionFee,jdbcType=REAL}, 
 #{item.promotionDesc,jdbcType=VARCHAR}, #{item.promotionId,jdbcType=VARCHAR}, #{item.giftItemId,jdbcType=VARCHAR}, 
      #{item.giftItemName,jdbcType=VARCHAR}, #{item.giftItemNum,jdbcType=INTEGER}, #{item.pmtType,jdbcType=VARCHAR}, 
      #{item.updateTime,jdbcType=TIMESTAMP}, #{item.createTime,jdbcType=TIMESTAMP})
    </foreach>
  </insert>

批量更新:


<update id="updateBatch" parameterType="java.util.List">
      <foreach collection="list" item="item" index="index" separator=";" >
      UPDATE order_source
    SET
        lastmodify =#{item.lastmodify},
        update_time=#{item.updateTime}
    WHERE order_id=#{item.orderId}
    </foreach>
</update>

批量插入的separator是逗号,批量更新的separator是分号;其他的没有太大区别
