Chess makes a fantastic game for programming examples. You will find hundreds of examples on the internet. Some dedicated to OO patterns, others to algorithms and so forth. Unfortunately, most of these examples do not use a database or if they do, treat the database as nothing more than a storage repository. In this series of articles we will use SQL Server and T-SQL to implement the game of chess with an emphasis on thinking in sets.

Sql Server comes with a host of built in functions such as ISNULL, CONVERT and CAST. Now if that wasn't enough rope to hang ourselves with, as of Sql Server 2000 we gained the ability to create our own user defined functions. In this article I will be looking at the three main date functions DATEADD, DATEPART and DATEDIFF (there is a fourth called DATENAME but I want to get to the end of this article before you fall asleep so I decided to leave it for another date and time! And no it doesn't foretell the name of your future blind date so it's not as interesting as it sounds anyway) Then I will be combining all three in a user defined function of our own by which time our necks will be well and truly stretched

The .NET Framework 2.0 introduces a very handy new class in the System.Data.SqlClient namespace called SqlBulkCopy that makes it very easy and efficient to copy large amounts of data from your .NET applications to a SQL Server database. You can even use this class to write a short .NET application that can serve as a "middleman" to move data between database servers.

On SQL Server 2025, I have a database that has this collation: SQL_Latin1_General_CP1_CI_AS. I decide I want to run this code:
SELECT UNISTR('*3041*308A*304C*3068 and good night', '*') AS 'A Classic';
I get this error:Msg 9844, Level 16, State 4, Line 24 The char/varchar input type uses an unsupported collation. Only a UTF8 collation is supported with char/varchar input type in UNISTR function.What is the easiest way to fix this error? See possible answers
