Description

Follow query work differently in 10.1 and 10.2.4:

            SELECT * FROM

            (SELECT @row := @row + 1 as row, a.* from (

                SELECT t.order_number

                FROM sales_documents t

                WHERE

                    t.type = 2 AND

                    `t`.`date` >= '2017-01-01' AND

                    `t`.`date` <= '2017-12-31' AND

                    `t`.`order_number` is not NULL AND

                    t.generated = 1

                GROUP BY t.order_number

                ORDER BY order_number ASC

            ) a, (SELECT @row := 0) r) t

            WHERE row <> order_number

What it does: This query should fetch natural numbers that omitted in order_number. This query should help find "empty space" in order_number list. Order numbers should be row of natural numbers from 1 to N and results set if we sort data by order_number should be list or natural numbers from 1 to MAX(order_number).

So, in 10.1 it works correctly and fetch "empty space" but in 10.2 after adding WHERE row <> order_number it broke result set.

Schema of this table:

CREATE TABLE `sales_documents` (

	`id` INT(11) NOT NULL AUTO_INCREMENT,

	`sale_id` INT(11) NULL DEFAULT NULL,

	`type` TINYINT(1) UNSIGNED NULL DEFAULT NULL,

	`data` TEXT NULL DEFAULT NULL COLLATE 'utf8_unicode_ci',

	`date` DATE NULL DEFAULT NULL,

	`order_number` INT(11) UNSIGNED NULL DEFAULT NULL,

	`created_at` INT(11) NULL DEFAULT NULL,

	`updated_at` INT(11) NULL DEFAULT NULL,

	`generated` TINYINT(1) NOT NULL DEFAULT '0',

	`synced_at` INT(11) NOT NULL DEFAULT '0',

	`sum` DECIMAL(13,2) NOT NULL DEFAULT '0',

	PRIMARY KEY (`id`)

COLLATE='utf8_unicode_ci'

ENGINE=InnoDB

AUTO_INCREMENT=1047

Data for test:

INSERT INTO `sales_documents` (`id`, `sale_id`, `type`, `order_number`, `data`, `created_at`, `updated_at`, `date`, `generated`, `synced_at`, `sum`) VALUES
