Product listing make query with "SELECT DISTINCT"


Recommended Posts

Hi Folks,


Currently I'm developing a specific module for a site, which makes some associations to _products table.


Via override i'd like to extend the list with one column (related above)


The problem is, that there're suddenly duplicate row(s) in the list. When i copy out the query, and extend SELECT with DISTINCT all things goes well natively.


The real question: is there a "standard" way to make select "distinty" (tried $this->_select, but there writes it at the middle of the fieldlist)



One more thing: tried the
$this->_group = ' GROUP BY a.`id_product`'
which gave the correct list, but this way the summary number is incorrect (up-left-corner)

I'm facing the same problem... have you found the solution?

I tried :

$this->_select = 'distinct(a.id_carrier),b.*'

But it doesn't work...

Thanks in advance,
