When information is exchanged in XML format, there needs to be an agreement between the sender and receiver about the structure and content of the XML document. An XSD (XML Schema Definition Language) Schema can be used to enforce this contract and validate the XML data being exchanged. Jacob Sebastian's book explains all.

FILESTREAM is implemented as an extension to the VARBINARY(MAX) data type and allows large object data to be stored in a special folder on the NTFS file system, while bringing that data under the transactional control of SQL Server. This book describes both the way it works and the implementation, administration and troubleshooting of it.

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
