MySQL - Slow query - mysql
Sorry for the long post, but the tables involved are quite big.
When I run the query bellow it normally takes about 1m to run. However, when I remove the correlated sub-query I get the query down to 15 seconds. So I think that's the actual problem.
Problem is, I don't really know how to get the SUM results without the correlated query.

The explain result from this query is quite big
I believe the subquery is being executed once per row in the group by clause.
Could you try the following if it makes it any better.
Change i have done is to perform the correlated query as a inline-view and then join with the main table/view -- company.vat
SELECT cl_clients.vat as association_vat, cl_clients.name as association_name, cl_clients_with_regions.city_id, cl_clients_with_regions.nut_1, cl_clients_with_regions.nut_2, cl_clients_with_regions.nut_3,

INNER JOIN cl_clients_with_regions company ON cl_clients_with_regions.vat = company.vat
LEFT JOIN (SELECT cl_finances.vat
,SUM((COALESCE((cl_finances.sales_community_market), 0) + COALESCE((cl_finances.sales_extra_market), 0))) as sum_val

WHERE `cl_clients_with_regions`.`encrypted_vat` IS NOT NULL
AND `cl_clients_with_regions`.`country` IS NOT NULL
AND `cl_clients_with_regions`.`cae` IS NOT NULL

AND `cl_clients_with_regions`.`division` IS NOT NULL
AND `cl_clients_with_regions`.`section` = 'A'
AND `cl_clients_with_regions`.`nut_2` = 'Centro'
GROUP BY association_vat;
To further explain the above answer:
Subqueries should never be in the select clause because they execute once per record that is returned / or calculated to return. This causes the query to get slower and slower as the database gets larger.
Instead, the subquery should be in the FROM clause, and the result of the subquery should be joined to and selected.

But so many records will breach the limit of my RAM, if i will save it in array or JSON.
Be aware that count(user_id) counts the number of rows that have user_id IS NOT NULL. It seems like it won't be NULL, so you may as well do COUNT(*). In older versions ANY_VALUE(date) does not work but MIN(date) works. There are lot of IN(...) lists; this makes it virtually impossible to fashion any useful INDEXes.

What is the value of innodb_buffer_pool_size? How much RAM? How big are the tables (in GB)? If things can't be cached adequately, then I/O is the problem and I will suggest changing BIGINTs (8 bytes each) to more civilized datatypes. "two merged tables have combined 30 million rows" -- Is it 30M before or after filtering (WHERE)? Please provide EXPLAIN SELECT ...

Your primary key field txn_signature is an auto increment field. This means the database will create a unique value for it automatically when you insert a new row. Therefore you should not include this field in your INSERT statement - the database will take care of it for you. Right now it thinks you're trying to override the automatic functionality and insert a value of "d4208b15558a761c34dc7c79b87275b4" manually. Obviously this would result in duplicate IDs once you have more than one row, so it's not allowed. Also, your field is an int and you're trying to insert a string into it, which will never work either.
No auto Increment when MySql Database converted to Postgres database
In Mysql, ID is Auto Increment but when converted to Postgres there is no Auto Increment . Mysql database CREATE TABLE IF NOT EXISTS `cities` ( `id` bigint(20) NOT NULL AUTO_INCREMENT, `state_id` bigint(20) NOT NULL, `district_id` bigint(20) NOT NULL, `name` varchar(255) NOT NULL, `description` varchar(1000) DEFAULT NULL, `created_by` int(11) NOT NULL, `modified_by` int(11) DEFAULT NULL, `is_active` char(1) NOT NULL DEFAULT 'Y', `created` datetime DEFAULT NULL, `modified` datetime DEFAULT NULL, PRIMARY KEY (`id`), KEY `state_id` (`state_id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=26 ; After Converted to postgres database CREATE TABLE cities ( "id" bigint NOT NULL, state_id bigint NOT NULL, district_id bigint NOT NULL, "name" varchar(255) NOT NULL, description varchar(1000), created_by int NOT NULL, modified_by int, is_active char(1) NOT NULL, created timestamp, modified timestamp, PRIMARY KEY ("id") ); INSERT INTO cities(state_id, district_id, city_type, name, description, created_by, modified_by, is_active, created, modified) VALUES (1, 1, '', 'Ramtek', null, 1, null, 'Y', '2015-04-16 10:44:11', '2015-04-16 10:44:11');
You could use bigserial in such cases. It provides an auto increment feature in postgres: CREATE TABLE cities ( "id" bigserial PRIMARY KEY, Not Null constraint is provided by default. Docs : http://www.postgresql.org/docs/current/static/datatype.html#DATATYPE-SERIAL
Unexpected behaviour of the query
This particular query is supposed to enter the user into the database. This query does not always insert the values of the firstname and the lastname fields along with others. firstname and lastname are empty for a few insertions and for the others its working as expected. INSERT INTO `users` (mobile, passwordHash, firstname, lastname, ent_id, email ) VALUES ('913800341127', '678a1491514b7f1006d605e9161946b1', 'nat', 'sam', '108', NULL) ON DUPLICATE KEY UPDATE `firstname` = VALUES(firstname),`lastname` = VALUES(lastname) Related Info: CREATE TABLE `users` ( `id` int(11) NOT NULL auto_increment, `tag` varchar(5) NOT NULL default 'ind', `username` varchar(50) default NULL, `firstname` varchar(100) default NULL, `lastname` varchar(100) default NULL, `passwordhash` varchar(255) NOT NULL, `secretq` varchar(255) default NULL, `secreta` varchar(100) default NULL, `email` varchar(50) default NULL, `mobile` varchar(13) default NULL, `last_login` datetime default NULL, `ent_id` bigint(20) NOT NULL default '1', `is_inactive` tinyint(1) NOT NULL COMMENT 'Whether the user is active or not', PRIMARY KEY (`id`), UNIQUE KEY `mobile_2` (`mobile`,`ent_id`), UNIQUE KEY `email_2` (`email`,`ent_id`), KEY `username` (`username`), KEY `ent_id` (`ent_id`,`tag`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1
syntax error it should be : ON DUPLICATE KEY UPDATE firstname = 'nat',lastname = 'sam'
