编辑：错误的原因（见下文）：我在doctrine_pi.php中的默认主键是“id”，因此我将其更改为“book_id”（我的数据库的主键）并且它有效。谢谢Marc B。
您好， 我正在使用CI + Doctrine + MySQL，我收到以下CRUD错误：
（1）尝试使用以下代码在数据库中创建新记录时：
$ book_title ='伯罗奔尼撒战争';
$ b =新书（）;
$ b-＆gt; title = $ book_title;
$ b-＆gt; price = 10.50;
$ B-＆GT;保存（）;
我收到此错误：
致命错误：未捕获的exeption'Doctrine_Connection_Mysql_Exception'，消息'SQLSTATE [42S22]：未找到列：1054'字段列表'中的未知列'title'...
（2）尝试从数据库中获取记录并使用以下代码显示在我的视图页面时：
$ book_title ='伯罗奔尼撒战争';
$ title = $ book_title;
$ search_results = Doctrine :: getTable（'Book'） - ＆gt; findOneByTitle（$ title）;
echo $ search_results-＆gt; title; //（在视图文件中）
我收到此错误：
致命错误：未捕获异常'Doctrine_Connection_Mysql_Exception'，消息'SQLSTATE [45S22]：未找到列：1054'字段列表中的未知列'b.id'...
最后，当我尝试按如下方式更新记录时：
$ book_title ='伯罗奔尼撒战争';
$ title = $ book_title;
$ u = Doctrine :: getTable（'Book'） - ＆gt; find（$ title）;
$ u-＆gt; title = $ title;
$ U-＆GT;保存（）;
我得到了类似的错误：
致命错误：未捕获的异常 'Doctrine_Connection_Mysql_Exception' 消息'SQLSTATE [42S22]：列 找不到：1054未知栏'b.id' 在“字段列表”中...
这是我的Doctrine_Record模型：
class Book extends Doctrine_Record{
public function setTableDefinition()
{
$this->hasColumn('book_id');
$this->hasColumn('isbn10','varchar',20);
$this->hasColumn('isbn13','varchar',20);
$this->hasColumn('title','varchar',100);
$this->hasColumn('edition','varchar',20);
$this->hasColumn('author_f_name','varchar',20);
$this->hasColumn('author_m_name','varchar',20);
$this->hasColumn('author_l_name','varchar',20);
$this->hasColumn('cond','enum',null, array('values' => array('as new','very good','good','fair','poor')));
$this->hasColumn('price','decimal',8, array('scale' =>2));
$this->hasColumn('genre','varchar',20);
}
public function setUp()
{
$this->setTableName('Book');
//$this->actAs('Timestampable');
}
最后，这是我的mysqldump：

我们非常感谢您的帮助。提前致谢。

MySQL的数据库，表和字段名称区分大小写。该表在MySQL中称为“book”，但您的Doctrine定义为$this->setTableName('Book');且大写为B
