Open Source and SQL Server communities
The other day, I was chatting to a keen PostgreSQL user. We're used to having free databases, such as IBM DB2 Express-C, Microsoft SQL Server 2005 Express Edition, SQLite and Oracle XE, but PostgreSQL is different in that it is open source. It is a proper, dedicated community too, I was told...
Options for scripting database objects
SQL Server Management Studio is rich with features. So rich, in fact, that after almost 3 years I am still finding new tools in the application that afford me more control over my databases and the methods for supporting them. Recently I found myself needing to script out a database and its objects for reviewing a problem offline.

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
