hi all, I built two mediawiki(wiki1,wiki2),and each of them has a database(wikidb1,wikidb2).I want to use both of the database in wiki1.That's mean I can query the data which belong to wikidb2 in wiki1.

I have already use the following code in wiki1.

$dbName = "wikidb2";

$dbw = wfGetDB( DB_MASTER ); $dbw->selectDB( $dbName );

$pageId = $dbw->selectField( 'page','page_id',

array( 'page_title' => $title,

'page_namespace' => 0 ),

__METHOD__); But it didn't work.

Is there any way or any function to solve this problem?

Thanks a lot
