PHP PDO 中的 DB2 时间戳格式

Question

我已经 PHP 通过 ODBC 和 EasySoft 驱动程序与 DB2（Ubuntu 14.04 上的 v10.5）通信。我在使用 select id from new table(insert ....) 格式进行查询时遇到时间戳格式问题。

这是我的 table:

$create = "create table permissions (
        id int not null generated always as identity,
        name varchar(255) not null,
        display_name varchar(255),
        description varchar(255),
        created_at timestamp default current_timestamp not null,
        updated_at timestamp default current_timestamp not null
      )";

$pdo->prepare($create)->execute();

效果很好，原始 PDO 插入也是如此：

$sth = $pdo->prepare("insert into permissions (name, display_name, description, updated_at, created_at) values (?, ?, ?, ?, ?)");
$sth->execute([
"client_admin_dashboard",
"Client Admin Dashboard",
"Can view overview of team",
"2015-07-09 14:10:50.000",
"2015-07-09 14:10:50.000"
]);

但是如果我尝试执行 select id 样式查询（使用相同的绑定）：

$sth = $pdo->prepare("select id from new table(insert into permissions (name, display_name, description, updated_at, created_at) values (?, ?, ?, ?, ?))");

我收到以下错误：

Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[22007]: Invalid datetime format: -180

如有任何帮助，我们将不胜感激！

非常感谢

编辑：

将变量移动到查询本身而不是使用绑定效果很好：

$sth = $pdo->prepare("select id from new table(insert into permissions (name,
display_name, description, updated_at, created_at) values ( 
'client_admin_dashboard', 'Client Admin Dashboard', 'Can view overview of 
team', '2015-07-09 14:10:50.000', '2015-07-09 14:10:50.000'))")->execute();

Answer 1

真是奇怪。如果我尝试从 CLP 静态执行您的命令，一切正常：

select id from new table(insert into permissions (name, display_name, description, updated_at, created_at) values ( 'client_admin_dashboard', 'Client Admin Dashboard', 'Can view overview of team', '2015-07-09 14:10:50.000', '2015-07-09 14:10:50.000'))

ID
-----------
          2

 1 record(s) selected.

会不会是 ODBC 驱动程序（或区域设置）以某种方式弄乱了时间戳格式？为了确认这一点，我能想到的唯一方法是采用 DB2 CLI 和服务器跟踪，它应该显示从客户端接收到的时间戳数据。

附带说明一下，我注意到 created_at 和 updated_at 的顺序在失败的情况下颠倒了：

...(insert into permissions (..., updated_at, created_at)...

一个愚蠢的问题，但是如果你修改顺序会怎样？

Answer 2

驱动程序供应商发布了一个修复程序。他们无法追踪问题：

It took a bit of tracking down because the issue only occurs on your PHP version with that exact PDO-ODBC version. It doesn't give the same results if you are out by even .0.1 of a version.
