Сидить замовник такий не тужить тай думку гадає, а що це я буду платити півтори куска спеціалусту за роботу, як є "профі" за 500 доларів, а тут ше і Вася програміст каже, а шо це ти будеш платити таку суму, як я зроблю дешевше за 300! Настрій хороший, угода укладена, робота кипить. Проходить не так багато часу, як замовник каже, а що це сторінка 2хв грузиться, а Вася каже, то нічо ми то все оптимізуємо! Проходить ще декілька місяців, а результату нема. Тоді замовнек розуміє, що Вася не профі і шукає профі в Х рази дорощого! Не так багато часу пройшло, як профі за 1000 каже, я в два рази оптимізував, більше не реально! Замовник пригнічений, шукає профі, і в один прекрасний момент знаходиться дійсно профі, який по домовленості в зарплату X оптимізував, повикидував, переписав, дописав і в результаті 50 мс при 500000 записів. Підсумок: 300 + 1000 + X != 300 :)

Высрал вот такое говно в качестве write-n-throw скрипта.

Дано: есть элементы дерева, хранящиеся в таблице sprinter_catalog_tree, связаны друг с другом через parent_id. Каждому из них соответствует указанный в info_id элемент таблицы sprinter_catalog_info.

Задача: скопировать все вложенные в раздел @from каталога элементы и его подразделы (вложенность не более 1 уровня) в раздел @to, так чтобы у них были новые id, и также скопировать соответствующие им sprinter_catalog_info. Скопированные sprinter_catalog_tree должны указывать на корректные sprinter_catalog_info, id которых заранее не известны.

Вот такое говно получилось, расскажите как надо было?

-48*4 as qty from Product
тоже не помогло.

sql ex рейтинговое 4. показывает что на тренировочной что-то не правильно.
лайк же вроде проверяет '1' как цифру а не как строку.
любые хинты как тут

В конкате первый аргумент concat(CAST(trip_no &1024 aS bit),
&1024 имеется ввиду

а внизу проверка where trip_no<=2048 and trip_no>=1024 - правильно ли ? или where trip_no<=1024and trip_no>=512 должно быть ?

и есть ли более профитный вариант решения рейтинговой задачи sqlex`a ? а то какой-то говнокод получается около 11к строк а там лимит 8к...
или лучше заменить на %2 и /2)%2 , /2)/2)%2 ????
