Question of the Day

The Maximum Value in the Identity Column

I have a table with this data:

TravelLogID CityID StartDate  EndDate
1           1      2025-01-01 2025-01-06
2           2      2025-01-01 2025-01-06
3           3      2025-01-01 2025-01-06
4           4      2025-01-01 2025-01-06
5           5      2025-01-01 2025-01-06
I run this code:
SELECT IDENT_CURRENT('TravelLog')
I get the value 5 back. Now I do this:
SET IDENTITY_INSERT dbo.TravelLog ON
INSERT dbo.TravelLog
(
    TravelLogID,
CityID,
    StartDate,
    EndDate
)
VALUES
(25, 5, '2025-09-12', '2025-09-17')
SET IDENTITY_INSERT dbo.TravelLog OFF
I now run this code.
DBCC CHECKIDENT(TravelLog)
GO
INSERT dbo.TravelLog
(
    CityID,
    StartDate,
    EndDate
)
VALUES
(4, '2025-10-14', '2025-10-17')
GO
What is the value for TravelLogID for the row I inserted for CityID 4 and dates starting on 14 Oct 2025?
