批量插入，批量修改的sql

sql 1  批量插入

<insert id="batchInsert" useGeneratedKeys="true" parameterType="java.util.List" >
    <selectKey resultType="long" keyProperty="id" order="AFTER">
        SELECT
        LAST_INSERT_ID()
    </selectKey>
    insert into user_contacts_info (id,user_id,old_id,cont_type,
    cont_ship, cont_status, cont_source,
    cont_user_name, cont_id_card, cont_mobile1,
    cont_mobile2, cont_mobile3, cont_tell,
    cont_addr, cont_addr_hk, cont_addr_com,
    cont_tell_com, e_mail, remark, create_time,
    cont_name_com,update_time)
    values
    <foreach collection="list" item="item" index="index" separator="," >
    (#{item.id,jdbcType=INTEGER},#{item.userId,jdbcType=INTEGER},#{item.oldId,jdbcType=INTEGER}, #{item.contType,jdbcType=VARCHAR},
    #{item.contShip,jdbcType=VARCHAR}, #{item.contStatus,jdbcType=VARCHAR}, #{item.contSource,jdbcType=VARCHAR},
    #{item.contUserName,jdbcType=VARCHAR}, #{item.contIdCard,jdbcType=VARCHAR}, #{item.contMobile1,jdbcType=VARCHAR},
    #{item.contMobile2,jdbcType=VARCHAR}, #{item.contMobile3,jdbcType=VARCHAR}, #{item.contTell,jdbcType=VARCHAR},
    #{item.contAddr,jdbcType=VARCHAR}, #{item.contAddrHk,jdbcType=VARCHAR}, #{item.contAddrCom,jdbcType=VARCHAR},
    #{item.contTellCom,jdbcType=VARCHAR},#{item.eMail,jdbcType=VARCHAR}, #{item.remark,jdbcType=VARCHAR},
    #{item.createTime,jdbcType=TIMESTAMP}, #{item.contNameCom,jdbcType=VARCHAR},
    #{item.updateTime,jdbcType=TIMESTAMP})
    </foreach>
</insert>

sql 2 批量插入，表设置为主键自增长

<insert id="insertByBatch" parameterType="java.util.List">
     insert into monitor_log
     (monitor_id, monitor_date, monitor_stats,
     monitor_info,
     monitor_product_id, monitor_repair_date,
     monitor_repair_userid)
     values
     <foreach collection="list" item="item" index="index"
              separator=",">
         (#{item.monitorId,jdbcType=INTEGER},
         #{item.monitorDate,jdbcType=TIMESTAMP},
         #{item.monitorStats,jdbcType=TINYINT},
         #{item.monitorInfo,jdbcType=VARCHAR},
         #{item.monitorProductId,jdbcType=INTEGER},
         #{item.monitorRepairDate,jdbcType=TIMESTAMP},
         #{item.monitorRepairUserid,jdbcType=INTEGER})
     </foreach>
 </insert>

sql 3 批量修改

 <update id="updateBatch" parameterType="java.util.List">
  update monitor_log
 <trim prefix="set" suffixOverrides=",">
 <trim prefix="monitor_date =case" suffix="end,">
     <foreach collection="list" item="item" index="index">
         <if test="item.monitorDate !=null ">
             when monitor_id=#{item.monitorId} then #{item.monitorDate,jdbcType=TIMESTAMP}
         </if>
     </foreach>
 </trim>

         </if>
     </foreach>
 </trim>
 <trim prefix="monitor_info =case" suffix="end,">
     <foreach collection="list" item="item" index="index">
         <if test="item.monitorInfo !=null ">
             when monitor_id=#{item.monitorId} then    #{item.monitorInfo,jdbcType=VARCHAR}
         </if>
     </foreach>
 </trim>
 <trim prefix="monitor_product_id =case" suffix="end,">
     <foreach collection="list" item="item" index="index">
         <if test="item.monitorProductId !=null ">
             when monitor_id=#{item.monitorId} then #{item.monitorProductId,jdbcType=INTEGER}
         </if>
     </foreach>
 </trim>
     where monitor_id in
     <foreach collection="list" index="index" item="item"
              separator="," open="(" close=")">
         #{item.monitorId,jdbcType=BIGINT}
     </foreach>
 </update>
