我试图从标题中描述的表中获取一些值，但我不知道如何，我已经尝试过，但它只返回最后一个值（b.name第二个选择的）：

SELECT * 
FROM (
(SELECT a.priority,a.ticket_status,a.title, b.name ,c.department_name, null, null 
FROM ".$SupportTicketsTable." a, ".$SupportUserTable." b, ".$SupportDepaTable." c 
WHERE a.enc_id=? AND b.id=a.user_id AND c.id=a.department_id LIMIT 1) 
UNION 
(SELECT null,null,null,null,null, b.mail,b.name 
FROM ".$SupportTicketsTable." a, ".$SupportUserTable." b 
WHERE a.enc_id=? AND b.id=a.operator_id LIMIT 1)) AS t2

执行查询后：

$result = $stmt->bind_result($prio, $stat, $tit, $name, $dpname, $tomail, $opname);
while (mysqli_stmt_fetch($stmt)){
$mail=$tomail;
$rep=array(
    '{TICKET_OPERATOR_NAME}'=>$opname,
    '{TICKET_CREATOR_NAME}'=>$name,
    '{TICKET_PRIORITY}'=>$prio,
    '{TICKET_STATUS}'=>$stat,
    '{TICKET_DEPARTMENT}'=>$dpname,
    '{TICKET_URL}'=>dirname(dirname(curPageURL())).'user/view.php?'.$argv[2],
    '{TICKET_TITLE}'=>$tit);
}

这是结果：

Array
(
    [{TICKET_OPERATOR_NAME}] => Adelaide
    [{TICKET_CREATOR_NAME}] => 
    [{TICKET_PRIORITY}] => 
    [{TICKET_STATUS}] => 
    [{TICKET_DEPARTMENT}] => 
    [{TICKET_URL}] => http://razorphyn.com/products/supportuser/view.php?e4e0d6dac254c905862480f8a16273f7c3157b80db2c2ad7f03306376da85ef451adf0cc71ce60.98140917
    [{TICKET_TITLE}] => 
    [{SITE_NAME}] => Razorphyn
    [{SITE_ADDRESS}] => http://razorphyn.com
)

这应该是最终输出：

    Array
(
    [{TICKET_OPERATOR_NAME}] => Adelaide
    [{TICKET_CREATOR_NAME}] => Pippo
    [{TICKET_PRIORITY}] => 0
    [{TICKET_STATUS}] => 1
    [{TICKET_DEPARTMENT}] => Support
    [{TICKET_URL}] => http://razorphyn.com/products/supportuser/view.php?e4e0d6dac254c905862480f8a16273f7c3157b80db2c2ad7f03306376da85ef451adf0cc71ce60.98140917
    [{TICKET_TITLE}] => Test
    [{SITE_NAME}] => Razorphyn
    [{SITE_ADDRESS}] => http://razorphyn.com
)

也许是这样：

SELECT 
a.priority,a.ticket_status ,a.title, b.name ,c.department_name,
tu.mail,tu.name 
FROM 
razorphyn_support_list_tickets a, 
razorphyn_support_users b, 
razorphyn_support_departments c,
razorphyn_support_list_tickets lt,
razorphyn_support_users tu
WHERE 
a.enc_id=? 
AND b.id=a.user_id 
AND c.id=a.department_id 
AND tu.id=lt.operator_id
LIMIT 1;

不确定您使用的是哪个数据库（假设它是 MySQL 或 Postgre），但您是否尝试过子选择：

SELECT a.priority,a.ticket_status,a.title, b.name ,c.department_name, d.mail, d.name 
FROM ".$SupportTicketsTable." a, ".$SupportUserTable." b, ".$SupportDepaTable." c,
     (SELECT b1.id, b1.mail,b1.name 
        FROM ".$SupportTicketsTable." a1, ".$SupportUserTable." b1
        WHERE b1.id=a1.user_id 
      ) d
   WHERE a.enc_id=? AND b.id=a.user_id AND c.id=a.department_id AND d.id = b.id LIMIT 1)  
) AS t2
