MsSQL Query - Упрощение кода - Отличная библиотека

У меня есть код ниже, но для работы требуется много времени. Есть ли способ упростить его? Мне нужен iotransactiondate в зависимости от iostatus на двух разных столбцах, поэтому мне пришлось присоединиться к тем же таблицам два раза.MsSQL Query - Упрощение кода

Особенно эта часть занимает слишком много времени, я думаю, но я не мог найти другого пути.

Этот запрос является зверем. У вас есть индексы в столбцах объединения, в частности на столбцах объединения выделенного места? Это может быть первое место для начала. –

@TimBiegeleisen уже 24 минуты, все еще исполняющий))) –

@TimBiegeleisen перед добавлением этой части, он работал медленно, но прекрасно ... на какие индексы я должен смотреть? (извините, не так много знаний) –

Удалены части соединения (tt. И ttt.) И выберите второй раз с помощью дополнительного запроса.
