MYSQL 选择表行，其中列在我的代码中的多个记录中包含相同的数据

Question

我这里有一个 mysql 代码 -

$querymypm = "SELECT * FROM pm WHERE recieverun='$uname' AND senderun='$c' ORDER BY pmid DESC";

但我想要这样 -

$querymypm = "SELECT * FROM pm WHERE recieverun='///(Taking more than one value)///' AND senderun='///(Taking more than one value)///' ORDER BY pmid DESC";

Answer 1

使用IN运算符。

$querymypm = "SELECT * FROM pm WHERE recieverun IN ('$uname1', '$uname2', '$uname3') AND senderun IN ('$c1', '$c2', '$c3') ORDER BY pmid DESC";
