This scalar udf takes three parameters @Number INT, @Length INT, @Position CHAR(1) and returns a VARCHAR(50) string which pads @Number with zeros to the specified @Length either to the right or to the left, according to @Position ('L' or 'R').E.g. SELECT dbo.udf_PadNumber(5, 6, 'L') returns '000005' whereas SELECT dbo.udf_PadNumber(5, 6, 'R') returns '500000'. The function […]

A script was recently published (Last_Date_Of_Month) that returns the last day of a given month/year combination. I have simplified and improved on that script by eliminating the need to use a WHILE loop. This new script exploits the flexibility of the DATEADD function which allows you to assign negative numbers (thus effectively subtracting a given […]

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
