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.

It should be easy to model a game of poker in SQL. The problem is, however, that you need to model a permutation from a set of elements.

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

Partitioning has improved with each new version of SQL Server. From partitioned views in SQL Server 7.0 through partition table parallelism in SQL Server 2008. With SQL Server 2012, we are now allowed to even create up to a 15K partition on a single table.
