Vygenerujte skript pro vytvoření všech indexů
Pracuji na dokumentování mých databází a chtěl bych vytvořit seznam všech indexů v mé databázi. Důvod, proč to chci udělat, je proto, abych mohl sledovat změny svých indexů přesčas. V současné době mám tabulku se všemi indexy, které se změnily od doby, kdy jsem ji vytvořil, ale neobsahuje všechny indexy. Místo toho, abych musel skriptovat každý index, chtěl bych jen vytvořit seznam. Hrál jsem se systémovými pohledy, ale nedokázal jsem to přijít.
Jak mohu vygenerovat seznam indexů a příkaz vytvoření pro každý index?
Zdá se, že takový skript v mém panelu nástrojů není, ale našel jsem nějaké další ve svém hledání.
Už jste tento skript viděli?

Používá kurzor, který pravděpodobně není nezbytně nutný. Obvykle je ale mohu vyčistit, abych se vyhnul kurzoru pomocí FOR XML a potenciálně nepředvídatelné aktualizace pro zřetězení řetězců.

Tuto odpověď jsem našel na mssqltips a toto je odkaz na článek Našel jsem tam.
V budoucnu také zveřejňuji TSQL pro případné link-rot .
