Joe has a bunch of small, easy to use scripts that can definitely be the beginning of a great set of monitoring tool. Amazing how much info you can gather with a little bit of code!

Analyzing the data storage in SQL Server databases is a bit of an art. It's a skill that takes some time to develop given that the tools are rather limited. DBCC SHOWCONTIG is one of the few ways in which you can get some insight into how SQL Server has structured your table on the disk. Joe Sack brings us another of his top xxx techniques with his ten queries that you can use to analyze the results of this command.

SQL Server showplan is a great tool for analyzing queries and determining whether or not more performance tuning needs to be done. However working with showplan can be confusing and it takes some practice to learn the ins and outs of what is occurring. Joseph Sack looks at showplan and seven of the main things that he is aware of when looking at the results. If you've rarely or never used showplan, this is a great article to get started in learning how an experienced DBA views the output.

Directly accessing system tables is discouraged - so what's the alternative? Using the Information Schema should allow you to create code that survives upgrades. Beyond that, what can you do with it? Joe has four great examples to get you started.

Joseph recently had to upgrade a server from 4g to 8g of memory. Read how he did it and learn about some interesting aspects of AWE. For example, if you have 6.5g configured for use by SQL, how will task manager show used by sqlserver.exe?

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
