Setting a not-default db adapter in zend framework 1.12 - sql-server

Question

i've a very specific problem, but i'm a niewbie with zend framework so i don't have idea of how exctly this db adapter works as a configuration, but i've already made a db connection with the default adapter of zend, and it was successful. Now i've to set two different database connections for two different db in the same application. So i've taken my application.ini and i've written the following lines:
;connessione al db
resources.db.adapter = pdo_mssql
resources.db.params.host = "ip"
resources.db.params.username = user
resources.db.params.password = pwd
resources.db.params.dbname = NAME
resources.db.isDefaultTableAdapter = true
resources.db.params.pdoType = dblib
;connessione al db1
resources.db1.adapter = pdo_mssql
resources.db1.params.host = "ip"
resources.db1.params.username = user
resources.db1.params.password = pwd
resources.db1.params.dbname = NAME
resources.db1.isDefaultTableAdapter = false
resources.db1.params.pdoType = dblib
then i went to my action controller and i wrote:
$db = Zend_Registry::get ( 'db' );
$result = $db->fetchRow("SELECT [Sell-to Customer No_] FROM dbo.SyncroPlanningTable WHERE id='".$id);
$rag_soc=$result->{"Sell-to Customer No_"};
$db1 = Zend_Registry::get ( 'db1' );
$result1 = $db1->fetchRow("SELECT [No_],[Name],[Address],[City],[Contact],[Name],[Phone] FROM `dbo.SOS$Customer` WHERE No_ = '".$rag_soc."'");
The error i'm getting is the following:
Fatal error: Uncaught exception 'Zend_Application_Bootstrap_Exception' with message 'Unable to resolve plugin "db1";
UPDATE:
My bootstrap.php is:
$resource = $this->getPluginResource ( "db" );
$db = $resource->getDbAdapter ();
$db->setFetchMode ( Zend_Db::FETCH_OBJ );
Zend_Db_Table_Abstract::setDefaultAdapter ( $db );
Zend_Registry::set ( "db", $db );
How can i change it? it is not mentioned in the manual page you gave me.

Answer 1

resources.db refers to Zend_Application_Resource_Db, so "db" here is not a variable name.
You should use Zend_Application_Resource_Multidb to support multiple database connections:
http://framework.zend.com/manual/1.12/en/zend.application.available-resources.html#zend.application.available-resources.multidb

Answer 2

Your code is expecting the DB adapters to be in the registry, so you need to grab them from the multiDB resource and store them:
$multiDB = $this->getPluginResource('multidb');
Zend_Registry::set('db1', $multiDB->getDb('db1');
Zend_Registry::set('db2', $multiDB->getDb('db2');
also, this line:
Zend_Db_Table_Abstract::setDefaultAdapter ( $db );
can be removed, as you're specifying the default adapter in the application.ini.
