我有一个带有unix时间戳，userID，Long和lat的表。我想从下一行复制Long和Lat的值，并将它们添加到该行。请参阅下文。

<table style="width: 645px;" border="0" cellspacing="0" cellpadding="0">
  <colgroup>
    <col width="140" />
    <col width="57" />
    <col span="7" width="64" />
  </colgroup>
  <tbody>
    <tr>

SELECT timestamp, userID, Long, Lat, Long as LongB, Lat as LatB FROM table

我认为你的意思是列而不是行
