PHP PDO選擇多行並插入到其他表LIMIT

Question

我有2個表equip_copy(copyID, equipment_id)並將其插入到表

mre_copy (mreID,copyID,equipment_id) 

我已經試過這個選擇查詢，但犯規的舉動。請任何人都可以幫助我？

$display = $con->query("SELECT copyID,equipmentID 
         FROM equip_copy 
         WHERE equipmentID= :eid 
         ORDER BY copyID DESC 
         LIMIT :elimit"); 

$display->execute(array("eid" => $id, "elimit"=>$request)); 

foreach($display as $row){ 

     $newCID = $row['copyID']; 
     $newEID = $row['equipmentID']; 

     $sql_table = "INSERT INTO mre_copy(mreID,equipmentID,copyID) values(?,?,?)"; 
     $stmt = $con->prepare($sql_table); 
     $stmt->execute(array($mreID,$newEID,$newCID)); 
} 

Answer 1

使用insert . . . select。我認爲這是你想要做

INSERT INTO mre_copy (mreID, equipmentID, copyID) 
    SELECT :mreID, copyID, equipmentID 
    FROM equip_copy 
    WHERE equipmentID = :eid 
    ORDER BY copyID DESC 
    LIMIT :elimit; 

我不知道在哪裏mreID來自什麼。如果它是自動遞增的，那麼就把它完全放在INSERT之外。
