Sometimes, you have to test out alternative indexing strategies, but the task of creating the candidate indexes would just take too long. Is there another way? Well, yes, why not use the same method the DTA (Database Tuning Advisor) uses, and take the tedium out of the job.

Despite NTEXT and TEXT being deprecated in SQL Server for some time they are still both used in production systems. In this article, I will briefly demonstrate the difference between a VARCHAR (MAX), NVARCHAR (MAX) and the NTEXT data types, and the impact on performance from using NTEXT/TEXT.

We often need to create similar SSIS packages which contain some common components such as connection managers, data flow components, log providers, event handlers, etc... So do we really need to create a package from scratch each time and add all these commonly used components in each package again and again. Is it possible to create a SSIS package with a basic structure/workflow and common components which can be used as template to create subsequent packages?

I saw your recent tip on Calculating Mathematical Values in SQL Server and have some related issues as I try to round values in my application. My users and me have a difference of opinion on some of the calculations in our reporting applications. All of the code is in T-SQL, but I think the reporting issues are related to data types and rounding down or rounding up rules. Do you have any insight into these issues? I would like to see some examples with a variety of coding options.
