连接正常。它是.MDB
最佳答案
您的根本问题是您没有在 fgetcsv() 函数中指定逗号分隔符。因此，推送到一列 date[0] 中的所有数据，并且 Access ACE/JET 引擎无法转换为第一列的日期/时间，全部呈现为零，在 unix time begins 中于 1970 年 1 月 1 日。
此外，请考虑使用 try/catch 捕获 PDO 异常。
try {
$import= $dbh->prepare("INSERT INTO adherence(
dateandtime,
lastname,
paidtime,
approvedtime,
notadhering) VALUES(
?,?,?,?,?)");
$i = 0;
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
if($i > 0) {
$data = str_replace('"', '', $data);
$import->bindParam(1, $data[0], PDO::PARAM_STR);
$import->bindParam(2, $data[1], PDO::PARAM_STR);
$import->bindParam(3, $data[2], PDO::PARAM_STR);
$import->bindParam(4, $data[3], PDO::PARAM_STR);
$import->bindParam(5, $data[4], PDO::PARAM_STR);
$import->execute();
}
$i++;
}
}
catch(PDOException $e) {
echo $e->getMessage()."\n";
}
对于日期，MS Access 日期/时间字段遵循当前 CPU 的语言时钟，例如 MM/DD/YYYY(美国)或 DD/MM/YYYY(英国)等。它不遵循其他 RDMS 的 YYYY-MM-DD 或此类变体的日期/时间格式。因此无需转换，因为您的 csv 已与 Access 格式对齐。话虽如此，您可能会收到警告:
SQLSTATE[22018]: Invalid character value for cast specification: -3030
但是，根据我的测试，数据库正确更新了所有行。通常，您会在日期字符串周围连接 # ，我尝试在您的代码中无济于事，但可能在您的绑定(bind)参数过程中，字符串类型不能与主题标签理想地包装在一起。
