Mybatis 批量插入数据

--mybatis 批量插入数据
--1、Oracle（需要测试下是否支持MySQL）

< insert id ="insertBatch" parameterType="List" > 
    insert into REAL_DATA_HW( M_LINE_NO,M_TIME,HW_NUM, VOL_A,VOL_B,VOL_C )
    < foreach collection ="list" item ="item" index ="index" separator ="union all"> 
     select    #{obj.M_LINE_NO,jdbcType= VARCHAR },to_date(#{obj.M_TIME ,jdbcType= VARCHAR },‘yyyy-MM-dd hh24:mi:ss‘),#{obj.HW_NUM , jdbcType=DOUBLE },
       #{obj.VOL_A ,jdbcType= DOUBLE },#{obj.VOL_B ,jdbcType= DOUBLE },#{obj.VOL_C ,jdbcType= DOUBLE } from dual
    </ foreach > 
</ insert >

--2、MySQL

< insert id ="insertBatch" parameterType="List" > 
<![CDATA[
    insert into REAL_DATA_HW( M_LINE_NO,M_TIME,HW_NUM, VOL_A,VOL_B,VOL_C )
    values 
]]>
    < foreach collection ="list" item ="item" index ="index" separator =","> 
       ( #{obj.M_LINE_NO},to_date(#{obj.M_TIME},‘yyyy-MM-dd hh24:mi:ss‘),#{obj.HW_NUM},
       #{obj.VOL_A},#{obj.VOL_B},#{obj.VOL_C} ) 
    </ foreach > 
</ insert >
