hy there. i love the title of your site.
thanks for your great work (sharing is caring).
well done care taker.

i was seriously looking for such solution.
this is my query:

“SELECT main_table.*, m.cat_title FROM linkcategory AS main_table LEFT JOIN linkcategory AS m ON main_table.parent_cat_id = m.cat_id”

what i was trying to achieve , to get the name of parent categories and make them filterable (naturally) but i after trying a lot. solved it in doing (type => ‘optons’) way. this column cat_title stays ambiguous , no matter what.
But i found very interesting the properties that are available for preparing columns ($this->addColumn(”,array(
” => ”
what more properties can be used here? please point me to the direction.
))
thank you.

This helped me a lot.
In my case I had ambiguous column for the mass action.
My resolve was as follows :

protected function _prepareMassaction()
{
$this->setMassactionIdField(‘main_table.entity_id’);

Note : table reference (‘main_table’).

Thanks for the direction!

My guess is that it’s the left join on the sub-query that’s causing this error:
LEFT OUTER JOIN (
SELECT user_id, count(*) AS properties_count
FROM properties
GROUP BY user_id
) AS properties_count ON properties_count.user_id = users.user_id

Does the query work without this join?
