The calculation of distance between two points using standard spherical geometry can be inaccurate for short distances (ten miles or less) because the sine function of very small angles approaches zero. The haversine approach (http://en.wikipedia.org/wiki/Haversine_formula) turns this around, so it is very accurate at small distances but has larger errors (about ten miles) for points […]

Both Sachinvaishnav and Mark Chad have submitted scripts to populate a column with a sequence number. The first solution uses a cursor; the second uses the SQL 2005 ROW_NUMBER() function.v1:http://www.sqlservercentral.com/scripts/viewscript.asp?scriptid=1643v2:http://www.sqlservercentral.com/scripts/viewscript.asp?scriptid=1664Since neither script requires a specific order for the sequence number, the same result can be achieved with a single UPDATE statement.

This function allows you to calculate the distance in miles or kilometers between any two points on the earth. I created to calculate the distance between two zip codes but is can be used for any two coordinates for which latitude and longitude is known.NOTE: A database for the coordinates of any US postal code […]

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
