从一个查询中的不同列中选择不同的表

我试图从标题中描述的表中获取一些值，但我不知道如何，我试过这个，但它只返回最后一个值（从一个查询中的不同列中选择不同的表

$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 
)

执行查询之后

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

：所述第二的b.name选择）

，这应该是最后的输出：

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 
)

你期望什么结果？ –

基本上所有的阵列应该可以完成，我更新的问题 – Razorphyn

更新，我要跌也是第一选择，并采取有关'C'表以外的部分？ – Razorphyn

也许这样：

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;

它的工作原理就像一个魅力，非常感谢你！ – Razorphyn

不知道哪些DB您使用（假设它是MySQL或Postgre）但你有没有尝试子选择：

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

每个派生的表必须有自己的别名，但是是MySQL的 – Razorphyn
