我怎么了 將varchar轉換為int數據類型時轉換失敗

Question

我不斷收到錯誤消息：將varchar值'BUY0'轉換為數據類型int時轉換失敗，我不確定代碼的問題所在。 cd_tp_1_item_no的列類型為varchar（30）

$customers = array("4470","3650","4322");

foreach($customers as $customer){

$sql = "SELECT DISTINCT cd_tp_1_item_no FROM oeprcfil_sql where cd_tp_1_cust_no = $customer";
$result = odbc_exec($conn,$sql);
$item[] = "";
        while ($row = odbc_fetch_array($result)) {

             $item = $row['cd_tp_1_item_no'];

    }


}

您可以使用下一條建議來解決您的問題：

$sql = "SELECT DISTINCT cd_tp_1_item_no FROM oeprcfil_sql where cd_tp_1_cust_no = '".(int)$customer."'";
