从上一个选择插入的PDO绑定参数

Question

When executing the following script, I get an error at my INSERT for invalid parameter number: no parameters were bound.

If I run the insert manually based on the previously selected values then it's fine. I know the syntax and relationships are all right. My issue is either in how I'm binding parameters or calling the execution.

Again, the first part of this script returns everything it needs, but my issue is occurring right at my insert statement, specifically erroring out after the insert statement is called.

Maybe It's still my lack of experience with PDO but from my docs it seems like this should work.

$order_ids = [];
while ($row = $ordStat->fetch(PDO::FETCH_ASSOC)) {
    $order_ids[] = $row['order_id'];
}
if (count($order_ids) > 0) {
    $placeholders = implode(',', array_fill(0, count($order_ids), '?'));
    $detailStatCheck = "
        SELECT 
             invnoc as INVOICE,
             fstatc as STATUS,
             cstnoc AS DEALER,
             framec AS FRAME,
             covr1c AS COVER,
             colr1c AS COLOR ,
             extd2d AS SHIPDATE,
             orqtyc AS QUANTITY
        FROM GPORPCFL
        WHERE invnoc IN ($placeholders)
    ";
    try {
        $detailCheck = $DB2conn->prepare($detailStatCheck);
        $detailRslt = $detailCheck->execute($order_ids);


        $count2 = $detailCheck->fetch();
        print_r($order_ids);
        print_r($count2);
    } catch(PDOException $ex) {
        echo "QUERY FAILED!: " .$ex->getMessage();
    }

    while ($row2 = $detailCheck->fetch(PDO::FETCH_ASSOC)){

        $insertPlacement = "
            INSERT INTO placements_new (sku_id, group_id, dealer_id, start_date, expire_date, locations, order_num)
                SELECT 
                     id, 
                     sku_group_id, 
                     :DEALER, 
                     DATE_ADD(DATE_FORMAT(CONVERT(:SHIPDATE, CHAR(20)), '%Y-%m-%d'),INTERVAL 7 DAY) as start_date,
                     DATE_ADD(DATE_FORMAT(CONVERT(:SHIPDATE, CHAR(20)), '%Y-%m-%d'),INTERVAL 127 DAY) as expire_date, 
                     :QUANTITY,
                     :INVOICE  
                FROM skus s
            WHERE  s.frame=:FRAME AND s.cover1=:COVER AND s.color1=:COLOR
        ";
        try{
            $insert = $MysqlConn->prepare($insertPlacement);
            $insertRslt = $insert->execute();
        }catch(PDOException $ex){
            echo "QUERY FAILED!!!: " . $ex->getMessage();
        }

    }
}

You need to actually bind the parameters (the error is helpful here: invalid parameter number: no parameters were bound ). You need to pass execute() an array containing the value to be assigned to each parameter:

$values = [
    ":DEALER" => $row2["DEALER"],
    ":SHIPDATE" => $row2["SHIPDATE"],
    ":QUANTITY" => $row2["QUANTITY"],
    ":INVOICE" => $row2["INVOICE"],
    ":FRAME" => $row2["FRAME"],
    ":COVER" => $row2["COVER"],
    ":COLOR" => $row2["COLOR"],
];

And then

$insertRslt = $insert->execute($values);

Notice that if you have ATTR_EMULATE_PREPARES set to false , you can't have one named parameter used two (or more) times, so you'll need to have :SHIPDATE as :SHIPDATE and :SHIPDATE2 and the respective additional value in the $values array.
