Many times we need to know what is the current identity of the column. I have found one of my developer using aggregated function MAX() to find the current identity.
USE AdventureWorks
GO
SELECTÂ MAX(AddressID)
FROM Person.Address
GO
However, I prefer following DBCC command to figure out current identity.
USE AdventureWorks
GO
DBCC CHECKIDENT ('Person.Address')
GO
