通过php将一个表中的一个字段与mysql中花药表中的几个字段进行比较

Question

我有这条线

$sql_events = mysql_query("SELECT team FROM weekpicks WHERE whatweek='$totalnoOfWeek'-1 and team in ( SELECT team1 FROM weekslosers WHERE whatweek='$totalnoOfWeek'-1 ) ORDER BY 'username' asc ")

它可以工作，但我还需要检查一下team2，team3等。 我以为可以做下面的事情，但是没有用。 似乎停在team1

$sql_events = mysql_query("SELECT team FROM weekpicks WHERE whatweek='$totalnoOfWeek'-1 and team in ( SELECT team1 FROM weekslosers WHERE whatweek='$totalnoOfWeek'-1 ) or ( SELECT team2 FROM weekslosers WHERE whatweek='$totalnoOfWeek'-1 ) ORDER BY 'username' asc ")

还是应该以其他方式完成？

我要做的是从桌上的周票中拿出球队，并将其与桌上的周输者中的球队进行比较，而周输者表中最多可以有8支输球队伍，所以如果您的球队是8支队伍之一，我需要将其列出。

Answer 1

SELECT team
FROM weekpicks
INNER JOIN weekslosers ON weekpicks.whatweek = weekslosers.whatweek
WHERE weekpicks.whatweek = (whatever) AND team IN (weekslosers.team1, weekslosers.team2)

另外，您应该考虑从mysql_ *过渡到mysqli或PDO。
