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?

I have added a few indexes to one of my tables in SQL Server 2025:
ALTER TABLE dbo.CustomerContact
ADD CONSTRAINT PK_CustomerContact
PRIMARY KEY (CustomerID);
-- Create index on CustomerEmail
CREATE INDEX IX_CustomerContact_CustomerEmail
ON dbo.CustomerContact (CustomerEmail);
CREATE INDEX IX_CustomerContact_CustomerPhone
ON dbo.CustomerContact (phone);
I then do this to disable one index:
alter index IX_CustomerContact_CustomerPhone on dbo.CustomerContact disableI see this when I check the index status:
I decide to rebuild all indexes with this command:
ALTER INDEX ALL ON dbo.CustomerContact rebuildAfter I do this, what will I see for the index status? See possible answers
