我通过ODBC和EasySoft驱动程序让PHP与DB2(Ubuntu 14.04上的v10.5)进行了交谈。使用select id from new table(insert ....)
格式进行查询时,我遇到时间戳格式问题。
这是我的表:
$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();
这与原始PDO插入一样正常:
$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"
]);
但是如果我尝试进行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

非常感谢任何帮助!
非常感谢
编辑:
将变量移动到查询本身而不是使用绑定可以正常工作:
$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();

这真的很奇怪。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'))

可能是ODBC驱动程序(或区域设置)以某种方式弄乱时间戳格式?为了确认这一点,我能想到的唯一方法是使用DB2 CLI和服务器跟踪,它们应该显示从客户端收到的时间戳数据。
在旁注中,我注意到created_at
和updated_at
的顺序在失败的情况下被颠倒了:
...(insert into permissions (..., updated_at, created_at)...
一个愚蠢的问题,但如果您修理订单会怎样?

驱动程序供应商发布了修复程序。他们无法追查问题:
这需要一些跟踪,因为问题只发生在具有完全PDO-ODBC版本的PHP版本上。如果你的版本甚至超过.0.1,它也不会给出相同的结果。
