MySQL:日期值不正确

Question

我正在解析具有以下数据结构的xml文件:

  <row Id="253858" UserId="40883" Name="Scholar" Date="2009-03-08T01:52:32.570" />
  <row Id="253860" UserId="19483" Name="Supporter" Date="2009-03-08T01:57:31.733" />
  <row Id="253861" UserId="74951" Name="Autobiographer" Date="2009-03-08T02:02:32.390" />

我使用ruby脚本来解析这些数据并将它们插入到mysql数据库中.以下是我的数据表的样子:

+---------+-------------+------+-----+-------------------+-----------------------------+
| Field   | Type        | Null | Key | Default           | Extra                       |
+---------+-------------+------+-----+-------------------+-----------------------------+
| id      | int(11)     | NO   | PRI | NULL              |                             |
| user_id | int(11)     | NO   |     | NULL              |                             |
| name    | varchar(40) | YES  |     | NULL              |                             |
| created | timestamp   | NO   |     | CURRENT_TIMESTAMP | on update CURRENT_TIMESTAMP |
+---------+-------------+------+-----+-------------------+-----------------------------+

这个xml文件有大量的记录,直到解析器到达第3条记录,我没有收到任何错误,所有数据都正确解析并插入到表中:

| 253857 |   23658 | Critic             | 2009-03-08 01:52:32 |
| 253858 |   40883 | Scholar            | 2009-03-08 01:52:33 |
| 253860 |   19483 | Supporter          | 2009-03-08 01:57:32 |
+--------+---------+--------------------+---------------------+

但是当我们得到记录时,row Id="253861"我得到以下mysql错误:

load.rb:21:in `execute': Incorrect datetime value: '2009-03-08T02:02:32.390' for column 'created' at row 1 (Mysql::Error)
    from load.rb:21:in `on_start_element'
    from load.rb:133:in `parse'
    from load.rb:133:in `<main>'

如果你需要插入记录的ruby方法:

  def on_start_element(element, attributes)
    if element == 'row'
      @st.execute(attributes['Id'], attributes['UserId'], attributes['Name'], attributes['Date'])
    end
  end
end

我不认为这与脚本有关,因为我从xml文件中提取记录并试图直接插入到我的mysql表中,我收到以下错误:

mysql> insert into badge values(253861,74951,'Autobiographer','2009-03-08T02:02:32.390');
ERROR 1292 (22007): Incorrect datetime value: '2009-03-08T02:02:32.390' for column 'created' at row 1

我还尝试在xml文件中插入上述记录之后的记录,我得到了相同的结果:

mysql> insert into badge values(253862,49628,'Teacher','2009-03-08T02:12:30.807');
ERROR 1292 (22007): Incorrect datetime value: '2009-03-08T02:12:30.807' for column 'created' at row 1

因此,日期字符串中的某些内容会使mysql不满意.我无法弄清楚的是,具有相同日期结构的日期和以前的记录没有任何问题.希望我已经用信息解释了问题.

Answer 1

既然你说你在几个地方插入日期我会建议你写和辅助方法进行日期转换,你可以在任何需要插入日期的地方重复使用

require 'date'
def iso8601_to_mysql_datetime(date)
  DateTime.parse(date).to_time.strftime("%F %T")
end

iso8601_to_mysql_datetime('2009-03-08T02:02:32.390')
=> "2009-03-08 02:02:32"

注意:上面将一个ISO8601字符串转换成MySQL了解MySQL的日期和时间文字文档可以在这里找到:
