mybatis Oracle 批量插入，批量更新

传入的参数只要是list类型的参数就行了。。。。。。。。。。。。。。1、批量插入

<insert id="insertBatch" parameterType="java.util.List">    INSERT INTO T_CITY_INDEX(    id,city_code    )    select SEQ_CITY_INDEX.NEXTVAL,cd.* from(    <foreach collection="list" item="item" index="index"  close=")" open="(" separator="union">        select        #{item.cityCode,jdbcType=VARCHAR},        #{item.cityName,jdbcType=VARCHAR}        from dual    </foreach>    ) cd</insert>

2、批量跟新

<update id="updateBatch"  parameterType="java.util.List">    <foreach collection="list" item="item" index="index" open="begin" close=";end;" separator=";">        update T_CITY_INDEX t        set        t.city_name= #{item.cityName,jdbcType=VARCHAR} ,        t.district_name= #{item.districtName,jdbcType=VARCHAR} ,        where t.id = #{item.id,jdbcType=NUMERIC}    </foreach></update>
