Question

版本：MySql 5.5，PHP 5.4

以下查询返回足球队的5个最近比赛日期，以及他们的净胜球和比赛ID。

$get_form = $conn->query("
SELECT (GoalsFor - GoalsAgainst) AS deficit, MatchID AS matchid 
FROM matches 
WHERE HomeTeamID = $homeid AND MatchDate < '$today'
ORDER BY MatchDate DESC
LIMIT 5
");

我正在使用下面显示的fetch来使用PHP检索5个结果。

while($data = $get_form->fetch_assoc())
   {
   if($data['deficit'] < 0)
       echo"Win ";
   else
       echo"Loss ";
   }

但结果目前按照从左到右的降序排列。我宁愿让它们按照从右到左的升序顺序出现。

我建议将ORDER BY更改为ASC，但这只会返回五个最老的匹配。我只希望在结果集中返回最近的五个（在今天的日期之前）。

Answer 1

SELECT *
FROM (
    SELECT (GoalsFor - GoalsAgainst) AS deficit, MatchID AS matchid 
    FROM matches 
    WHERE HomeTeamID = $homeid AND MatchDate < ?
    ORDER BY MatchDate DESC
    LIMIT 5
) X
ORDER BY MatchDate;
