坑爹的Yii对oracle的支持

首先感谢这篇文章：http://ihacklog.com/post/how-to-connect-to-two-or-more-databases-simutaneously.html

在他的帮助下，我成功配置了第二个连接，然后在一没有pdo经验，二没有在Yii下用过oracle的情况下，一点点摸索前进。

在成功连接oracle后，遇到一个天大的问题：The table "xxxx.tablename" for active record class "MyClass" cannot be found in the database。

我找了一个多小时，反复试验，就是找不到。我试图修改tnsnames.ora，未果。去掉点前面的xxxx，也不行。

如果直接使用sql，是可以的：

$sql="select * from xxxx.tablename";
$user=Yii::app()->db_oracle->crateCommand($sql)->queryAll();

百思不得其解。最后只好回过头来看yii的文档：

Names case-sensitivity

Column names in Oracle are case-sensitive. This means that if you use all uppercase characters when creating a table (common behaviour among Oracle developers) and then try to access it with model and ActiveRecord for example like this:

我试着把表名改为正确的大小写，通过了。

尼玛。。。
