when use MyBatis，and  execute batchSave also OOM

example:

    <insert id="batchSave">
        insert into table_name(id,column_a,column_b,date_time)
        <foreach collection="list" item="item" index="index" separator="UNION ALL">
            select sys_guid(),
            #{item.columnA,jdbcType=VARCHAR},
            #{item.columnB,jdbcType=VARCHAR},
            sysdate
            from dual
        </foreach>
    </insert>
