How I will access a table from another Databse in cakephp -

-

My project has two databases. I have declared two connection variables in database.php I like the following: 

  var $ development = array ('driver' = & gt; mysql ',' persistent '= & gt; wrong,' host '=> gtxxx', 'login' = & Gt; 'xxxx', 'password' = & gt; 'xxxx', 'database' = & gt; 'yyyy', 'prefix' =>;); Var $ production = array ('driver' = & gt; 'mysql', 'persistent' = & gt; wrong, 'host' = & gt; 'xxxxxx', 'login' => 'xx', 'password '= & Gt;' xx ',' database '=> gt;' xxx ',' prefix '=> gt;   
 Now I am using development as the default connection.  
 In a controller function, I need to get some value from some DAB. How do I get other DB data out there? If any body can help in this, I will make it very strange. Thank you in advance.   
 
 
 You can define which database to use by using $ useDbConfig in your model class For data source  
  class example AppModel extended {var $ useDbConfig = 'development'; } Class example AppModel extended {var $ useDbConfig = 'production'; }   
 and you can check the usage of extensions in the KPP document

In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...
