    update objectattribute set
    attributeName =
    <foreach collection="list" item="item" index="index" separator=" " open="case data_objectUID" close="end">
      when #{item.data_objectUID} then #{item.attributeName}
    </foreach>
    ,attributeID =
    <foreach collection="list" item="item" index="index" separator=" " open="case data_objectUID" close="end">
      when #{item.data_objectUID} then #{item.attributeID}
    </foreach>
    ,dataType =
    <foreach collection="list" item="item" index="index" separator=" " open="case data_objectUID" close="end">
      when #{item.data_objectUID} then #{item.dataType}
    </foreach>
    ,dataLength =
    <foreach collection="list" item="item" index="index" separator=" " open="case data_objectUID" close="end">
