I am trying to use Firebird 1.5 database with Yii with Yii-Firebird extension yii2-firebird | Extension | Yii PHP Framework

			yii2-firebird | Extension | Yii PHP Framework This extension adds Firebird database engine extension for the Yii framework 2.0.

I can connect to both Firebird 1.5 and 2.1 databases, but only from 2.1 database I can read table data. When I am trying to read data from Firebird 1.5 database I receive message:

<response>

<name>Invalid Configuration</name>

<message>The table does not exist: BANKS</message>

<code>0</code>

<type>yii\base\InvalidConfigException</type>

As far as I know then 1.5 and 2.1 are greatly compatible with regard to third party frameworks and tools (e.g. IBX, BDE can work with both versions), so - are there solution for Yii and Firebird 1.5?
