PHP MySQL的SELECT从其他表

Question

我有两个表：

players 
bans 

而且我有mysql查询：

$stmt = $this->db->prepare("SELECT ban_Type, ban_Reason FROM bans WHERE ban_Name = ? LIMIT 1"); 
$stmt->execute(array($_SESSION['admin_session'])); 

我想从另一个表中获取ID行..

$stmt = $this->db->prepare("SELECT ID FROM players WHERE Name = ? LIMIT 1"); 
$stmt->execute(array($_SESSION['admin_session'])); 

是否可以合并这两个查询？在此先感谢

这是一个有点硬不知道你的数据库结构做，但基本上这应该工作：

SELECT b.ban_Type 
    , b.ban_Reason 
    , p.Name 
FROM bans b 
    JOIN players p ON p.ID = b.players_ID 
WHERE ban_Name = ? 
LIMIT 1
