Optimistic Locking in SQL Server using the ROWVERSION Data Type
Using the default SQL Server READ COMMITTED isolation level, my application sometimes falls victim to the dreaded "lost update" condition where two of my users edit the same row for update but the user who submits his/her change last overwrites changes made by the other user. Is there a good way to check for this and prevent it?

Table-valued parameters – SQL Server 2008
In previous versions of SQL Server, it has not been possible to pass a table variable, as a parameter, to a stored procedure. Microsoft introduces table-valued parameters, along with other features, in SQL Server 2008. This article illustrates the function and usage of table-valued parameters.

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 2025-01-16The 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? See possible answers
