Я хочу создать script всех индексов в базе данных (Create Index).
Я не хочу индекс script вместе с create table script. как мы можем сгенерировать его в SQL Server (2005 или 2008). Для кластеризованных и некластеризованных индексов должен быть отдельный script.
Это отличная статья о SQL Server Central, которую я использовал.
Вот еще один, который вам может понравиться лучше.
Если это не совсем то, что вы ищете (сортировка, фильтрация), я уверен, что было бы легче отредактировать их, чем начинать с нуля.
Вот слегка исправленный (2019) код из первого примера:
