Here's a quick and dirty function for parsing strings based on a delimiter (As in a varchar field with comma delimited text). I'm hoping for feedback on a more efficient means of doing this.Also,4 functions for comparing two delimited lists of strings. Many may ask why these are needed, but that's a very long explanation […]

This is a utility proc that I use a lot for datawarehouse transformation/load processing. This is a generic proc for resequencing an integer column in sorted order within a given key combination.Note that 'key' is used here in a general context and not specific, that is there doesn't have to be any keys or indexes […]

Saw Mike's routine for counting occurences of a string in a string and I thought I'd offer a simpler solution.Simply replace the occurence with null and use length differences as shown.NOTE: len may ignore trailing spaces, so this can be made more solid by adding some non printable char (less likely to interfere with operation) […]

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
