結合多個獨特的MySQL表格並按一列排序

Question

我一直在嘗試在過去的幾天裏完成這個MySQL查詢，現在運行得很少。我想將這些多個表格和它們的列組合起來，然後按照它們的共同點（不是按名稱，而是按內容）排序。我有以下的數據庫表：

mb_bans：

mb_ban_records：

mb_kicks：

mb_mutes：

個

mb_mutes_records：

mb_warnings：

我試圖做到的是這一行中的東西：

不幸的是，我以後難倒如何將這些MySQL表組合在一起，同時將它們保存在不同的類別中 - 按每個表中的_time列排序。我會如何處理這個問題？我一直沒有成功地嘗試檢索它們。我能得到的最接近的結果是將每個列的_time列組合在一起，然後在查詢中給它一個值作爲「日期」的值，但是我無法對結果做很多工作。我仍然需要將它作爲單獨的行來調用，對嗎？我大概可以用使用fetchall但後來我將無法添加任何東西的價值..

$banq = $db->prepare('SELECT banned, banned_by, ban_reason, ban_time, ban_expires_on FROM '.BAN_TABLE.' ORDER BY ban_time DESC'); 
$kickq = $db->prepare('SELECT kicked, kicked_by, kick_reason, kick_time FROM '.KICK_TABLE.' ORDER BY kick_time DESC'); 
$muteq = $db->prepare('SELECT muted, muted_by, mute_reason, mute_time, mute_expires_on FROM '.MUTE_TABLE.' ORDER BY mute_time DESC'); 
$warnq = $db->prepare('SELECT warned, warned_by, warn_reason, warn_time FROM '.WARN_TABLE.' ORDER BY warn_time DESC'); 
$banq->execute(); 
$kickq->execute(); 
$muteq->execute(); 
$warnq->execute(); 

基本上我想所有這些查詢爲一體+兩個_Record表結合在一起。任何可以幫助我的建議都是非常值得讚賞的，因爲我花了無數個小時試圖自己解決這個問題。

提前致謝！

試試這個：

SELECT * from (
SELECT banned as Punisher, banned_by as Punished, ban_reason as Reason, ban_expires_on as Expire, ban_time as Date FROM mb_bans 
UNION 
SELECT kicked as Punisher, kicked_by as Punished, kick_reason as Reason, NULL as Expire, kick_time as Date FROM mb_kicks 
UNION 
SELECT muted as Punisher, muted_by as Punished, mute_reason as Reason, mute_expires_on as Expire, mute_time as Date FROM mb_mutes 
UNION 
SELECT warned as Punisher, warned_by as Punished, warn_reason as Reason, NULL as Expire, warn_time as Date FROM mb_warnings 
) d order by d.Date DESC; 

編輯

我怎麼能得到記錄的類型？（IE。返回的結果是否是從禁止表，靜音表，踢表等）

SELECT * from (
    SELECT banned as Punisher, banned_by as Punished, ban_reason as Reason, ban_expires_on as Expire, 'ban' as TableType, ban_time as Date FROM mb_bans 
    UNION 
    SELECT kicked as Punisher, kicked_by as Punished, kick_reason as Reason, NULL as Expire, 'kick' as TableType, kick_time as Date FROM mb_kicks 
    UNION 
    SELECT muted as Punisher, muted_by as Punished, mute_reason as Reason, mute_expires_on as Expire, 'mute' as TableType, mute_time as Date FROM mb_mutes 
    UNION 
    SELECT warned as Punisher, warned_by as Punished, warn_reason as Reason, NULL as Expire, 'warn' as TableType, warn_time as Date FROM mb_warnings 
    ) d order by d.Date DESC; 

Answer 2

對這個問題的通用的答案是，

SELECT A.COL, B. COL, C.COL 
FROM TABLE1 AS 'A' 
INNER JOIN TABLE2 AS 'B' WHERE A.ID = B.ID 
INNER JOIN TABLE3 AS 'C' WHERE B.ID = C.ID 
. 
. 
. 
<YOU CAN PUT AS MUCH AS JOINS YOU WANT> 
ORDER BY <REQUIRED_COL> 

現在，在巨大的情況下做到這一點。
