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?

This code:
$query = ”
SELECT
users.user_id, users.email,
users.first_name, users.last_name,
users.last_login, users.created, users.status,
countries.name AS country, provinces.name AS province, cities.name AS city, districts.name AS district,
properties_count.properties_count
FROM users
LEFT OUTER JOIN countries ON countries.country_id = users.country_id
LEFT OUTER JOIN provinces ON provinces.province_id = users.province_id
LEFT OUTER JOIN cities ON cities.city_id = users.city_id
LEFT OUTER JOIN districts ON districts.district_id = users.district_id
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
“;
id giving me the same error! Can you help me?

Hi Will, it worked for me but with a little change.
Instead of

$collection = Mage::getResourceModel(‘spinonesolutions_storelocator/retailer_collection’);

I used

$collection = Mage::getModel(‘spinonesolutions_storelocator/retailer_collection’)->getCollection();

If this change isn’t done, a warning will appear saying that getSelect() is not defined.
