Modifying Microsoft Access Linked Tables from SQL Server

In a previous tip we saw how easy it was to link to SQL Server tables from Microsoft Access. As is the case with all systems, how does Access manage the changes? What happens when you modify the structure of the underlying SQL Server table? What happens to the SQL Server table if you delete the linked table in Access? We will look at each of these situations in this tip.

The CLR

The CLR was one of the highly touted additions to SQL Server 2005, and one of the reasons for its long development cycle. Steve Jones comments on why it hasn't been that widely used.

Question of the Day

Checking Identities

The DBCC CHECKIDENT command is used when working with identity values. I have a table with 10 rows in it that looks like this: 

TravelLogID CityID  StartDate   EndDate
1           1       2025-01-11  2025-01-16
2           2       2025-01-11  2025-01-16
3           3       2025-01-11  2025-01-16
4           4       2025-01-11  2025-01-16
5           5       2025-01-11  2025-01-16
6           6       2025-01-11  2025-01-16
7           7       2025-01-11  2025-01-16
8           8       2025-01-11  2025-01-16
9           9       2025-01-11  2025-01-16
10          10      2025-01-11  2025-01-16
The docs for DBCC CHECKIDENT say this if I run with only the table parameter: "If the current identity value for a table is less than the maximum identity value stored in the identity column, it is reset using the maximum value in the identity column. " I run this code: 
DELETE dbo.TravelLog WHERE TravelLogID >= 9
GO
DBCC CHECKIDENT(TravelLog, RESEED)
GO
INSERT dbo.TravelLog
(
    CityID,
    StartDate,
    EndDate
)
VALUES
(4, '2025-09-14', '2025-09-17')
GO
What is the identity value for the new row inserted by the insert statement above?
