试试这个：
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 UNIOnSELECt kicked as Punisher, kicked_by as Punished, kick_reason as Reason, NULL as Expire, kick_time as Date FROM mb_kicks UNIOnSELECt muted as Punisher, muted_by as Punished, mute_reason as Reason, mute_expires_on as Expire, mute_time as Date FROM mb_mutes UNIOnSELECt 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;

我如何获得记录类型？ （即，返回的结果是否来自禁令表，静音表，反冲表等）
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;
