Auditing DDL Changes in SQL Server databases

  • Article

Even where Source Control isn't being used by developers, it is still possible to automate the process of tracking the changes being made to a database and put those into Source Control, in order to track what changed and when. You can even get an email alert when it happens. With suitable scripting, you can even do it if you don't have direct access to the live database. Grant shows how easy this is with SQL Compare.

SQL Server 2008 and 2008 R2 Integration Services - Analysis Services Execute DDL Task

  • Article

The term DDL designates Data Definition Language, which implies an action involving creating data structures. In the context of Analysis Services Execute DDL Task, this is a bit of a misnomer because its capabilities are much more diverse, extending to such areas as backups, restores, deletions, modifications, or processing. This is accomplished by employing Analysis Services Scripting Language (ASSL).

Question of the Day

Finding Trailing Spaces

I have some data in a SQL Server 2025 database. It looks like this for the dbo.Customer table:

CustomerID CustomerName PreferredName
1          Steve        Steve               
2          Andy         Andy               
3          Brian        Brian               
4          Allan        Allan               
5          Devin        Devin               
6          Steve        Steve               
7          Sally        Sally
I want to detect which names have a single trailing space. The CustomerName is a varchar() and the PreferredName is a CHAR(). Does this query detect the problem rows?
SELECT 
       CustomerID,
       CustomerName,
       PreferredName
FROM Customer
WHERE CustomerName <> RTRIM(CustomerName)
OR PreferredName <> RTRIM(PreferredName);
