【问题描述】：

我的 SELECT 查询正在正确获取所有内容，但我的插入失败，因为我的参数值包含太多的插入（frame2、cover2、color2 等）

我的第二次选择需要额外的参数，但插入不需要它们。

有没有办法执行我的插入并说“在没有 :frame2、:cover2、:color2、:frame3、:cover3、:color3 的情况下在 $salesValues 上执行”

$selectPlacements = "
    SELECT DISTINCT
        sku_id, s.frame as frame, sg.group_code as group_code, sg.name as group_name, s.cover1 as cover, s.color1 as color, dealer_id, sales_rep as repNum, count(*) as placements
    FROM place p
    inner join skus s 
    on p.sku_id = s.id
    inner join sku_groups sg 
    on sg.id = s.sku_group_id
    where p.expire_date > curdate()
    group by sku_id, s.frame, dealer_id
    ;
";

try 
    $placementCheck = $mysqlConn->prepare($selectPlacements);
    $detailRslt = $placementCheck->execute();

     while ($placementRow = $placementCheck->fetch(PDO::FETCH_ASSOC)) 

        print_r($placementRow); //This prints the array I need

        $salesValues = [
        ":dealer_id" => $placementRow["dealer_id"],
    ":frame" => $placementRow["frame"],
    ":cover" => $placementRow["cover"],
    ":color" => $placementRow["color"],
    ":frame2" => $placementRow["frame"],
    ":cover2" => $placementRow["cover"],
    ":color2" => $placementRow["color"],
    ":frame3" => $placementRow["frame"],
    ":cover3" => $placementRow["cover"],
    ":color3" => $placementRow["color"],
    ":group_code" => $placementRow["group_code"],
    ":group_name" => $placementRow["group_name"],
    ":placements" => $placementRow["placements"],
    ":repNum" => $placementRow["repNum"],
        ];

        $insertSales = "
            MERGE INTO Tmetrics AS T
                USING (VALUES (
                    CAST(:dealer_id as CHAR(10)),
                    CAST(:frame as CHAR(10)),
                    CAST(:cover as CHAR(10)),
                    CAST(:color as CHAR(10)),

            WHEN MATCHED
                THEN UPDATE SET last180days_sales = S.last180days_sales, velocity = S.velocity, repnumber = S.repnumber, last180_rep = S.last180_rep, velocityrep = S.velocityrep, last180company = S.last180company, velocitycompany = S.velocitycompany
             WHEN NOT MATCHED
                THEN INSERT VALUES(S.dealer, s.frame, s.cover, s.color, s.groupnum, s.groupname, s.last180days_sales,s.velocity,s.repnumber,s.last180_rep,s.velocityrep,s.last180company,s.velocitycompany,s.placements)
        ";
      try

                $velocityExecution = $velocityInsertPrep->execute($salesValues);

            catch(PDOException $ex)

                echo "INSERT_FAILED: " .$ex->getMessage();

            

【参考方案1】：

没有办法将值传递给 PDOStatement::execute() 并告诉 PDO 不要使用它们，但您可以很容易地不将这些值传递给 execute() 开始，使用纯 php array_diff_key()：

// Note, the actual values can be anything. The keys just need to be set.
$ignores = [
    'frame2' => false,
    'cover2' => false,
    'color2' => false,
]; 

$velocityExecution = $velocityInsertPrep->execute(array_diff_key($salesValues, $ignores));
