How to check date of last change in stored procedure or function in SQL server

Можно использовать, это для проверки изменяет дату functions и stored procedures вместе заказанный по дате:

SELECT 'Stored procedure' as [Type] ,name, create_date, modify_date 
FROM sys.objects
WHERE type = 'P' 

UNION all

Select 'Function' as [Type],name, create_date, modify_date
FROM sys.objects
WHERE type = 'FN'
ORDER BY modify_date DESC

или:

SELECT type ,name, create_date, modify_date 
FROM sys.objects
WHERE type in('P','FN') 
ORDER BY modify_date DESC
