刪除一行時，它被添加到不同的表

Question

我有2個表

登記的活動和事件，但我想，當按下按鈕它會從事件到註冊事件的事件顯示。 但我無法刪除事件本身 我可以隱藏它，所以它不會出現在網頁上的表？

我使用笨

！[在Cassey發佈領域分級劃痕種族事件是兩個表中] [1]

儘管你可以做這個事情變得簡單了很多，你可以嘗試擴展您的第一個查詢這樣的 - 如果我理解正確的話：

$this->db->select('*'); 
$this->db->from('tblMeetRace as met'); 
$this->db->join('tblLocation as loc', 'loc.intLocationID = met.intLocationID'); 
$this->db->join('tblEvent as eve', 'eve.intEventID = met.intEventID'); 
$this->db->join('tblRegistration as reg', 'reg.intMeetRaceID = met.intMeetRaceID', 'left'); 
$this->db->where(array("met.intMeetRaceID" => NULL));
