Question

我正在尝试使用PDO在php脚本中准备DB2插入，这给了我错误“参数标记或NULL无效”

我正在运行一个选择查询以获取值并将其设置为参数，然后设置了我的插入语句。我准备了它，并在基于第一个查询的访存的while循环中，设置了参数，以便能够使用所需的值运行插入。问题是它在我准备插入的行上失败了。

第一个查询运行并打印

[ORDERNUMBER] 123456
[CUSTOMER] 1
[PRODUCT] 123
[FABR] A
[COLOR] 1
[SHIPDATE] 20181119

所以数据又回来了，我什至开始转换数据类型，但仍然出现错误。

这是打印以上内容的初始选择：

//SELECT query to get source data
$getOrderDetails = "
    SELECT 
         cast(invnoc as int) as ORDERNUMBER,
         cast(cstnoc as int) AS CUSTOMER,
         cast(PRODUCTc as int) AS PRODUCT,
         cast(covr1c as int) AS FABR,
         cast(colr1c as int) AS COLOR ,
         cast(extd2d as varchar(45)) AS SHIPDATE,
    FROM testTable g
";

try {
    $orderDetailCheck = $DB2conn->prepare($getOrderDetails);
    $detailRslt = $orderDetailCheck->execute();
    $orderDetailCount = $orderDetailCheck->fetch();
    print_r($orderDetailCount);
}catch(PDOException $ex) {
    echo "QUERY ONE FAILED!: " .$ex->getMessage();
}

插入声明：

$insertPlacement = "
    INSERT INTO table (CUSTOMER_id, start_date, expire_date)
    SELECT DISTINCT
        :CUSTOMER, 
        (to_date(:SHIPDATE, 'YYYYMMDD') + 7 DAYS)  as start_date,
        (to_date(:SHIPDATE, 'YYYYMMDD') + 127 DAYS)  as expire_date
    from OFSTable ofs
    WHERE  ofs.PRODUCT=:PRODUCT AND ofs.FABR1=:FABR AND ofs.color1=:COLOR;
";

设置参数：

//this line is failing
$insert = $DB2conn->prepare($insertPlacement);

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

    $insertParams = [
        ":CUSTOMER" => $row2["CUSTOMER"],
        ":ORDERNUMBER" => $row2["ORDERNUMBER"],
        ":PRODUCT" => $row2["PRODUCT"],
        ":FABR" => $row2["FABR"],
        ":COLOR" => $row2["COLOR"],
    ];

我意识到问题是我不能将参数称为列名或表名，但这在mysql中有效，不适用于db2。我需要为：CUSTOMER参数插入值，但它的行为就像我不能那样做。我应该如何更改它以使其像在Mysql上一样在db2上工作？

您应该强制转换所有参数。像这样：

storageBucket

SQL Call builder returns 'A statement contains a use of a parameter marker that is not valid.. SQLCODE=-418, SQLSTATE=42610'

DB2选择设置参数，然后插入参数值
