Filter Magento collection but not products, using distinct

Question

In my magento store I am trying to retrieve a list of youtube videos from a DB table, some videos are duplicated.

I\'m looking to filter videos by using distinct vid

Answer 1

You can try this:

$collection->getSelect()->distinct(true);

But this will retrieve distinct values based on id. If you want to retrieve videos using distinct video values, you should group by "value".

$collection->getSelect()->group('value');

If you want to debug the query executed :

$collection->getSelect()->__toString();

Hope this helps
