Chcę wygenerować skrypt wszystkich indeksów w bazie danych (Utwórz indeks).Generowanie skryptu wszystkich indeksów w bazie danych
Nie chcę skryptu indeksu wraz ze skryptem tworzenia tabeli. jak możemy go wygenerować w SQL Server (2005 lub 2008). Musi istnieć osobny skrypt dla indeksów klastrowych i nie klastrowanych.
To jest excellent article na SQL Server Central, którego użyłem.
Oto another, które mogą Ci się spodobać.
Jeśli nie jest to dokładnie to, czego szukasz (sortowanie, filtrowanie), jestem pewien, że łatwiej byłoby je edytować niż zacząć od zera.
mogę zaproponować metodę to:

To był błąd Rachel; dzięki za twoją obserwację. Teraz usunąłem go i powinno być dobrze. –
