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.

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.

It is frustrating when you hit 'submit' and you get the hourglass big-time. Is it the database to blame? It could be, but there are other suspects that should be considered.

Then comes the second problem: how would you sort such a column-base permutation in order? Sorting columns in SQL?
