Most modern programming environments offers exception handling in some form, and SQL Server provides the popular TRY-CATCH concept. However, error handling in SQL Server is not as straightforward as one may wish, but it is marred with inconsistencies and surprises. This session starts off by displaying the some of the surprises you can encounter, both when you use TRY-CATCH and when you don't. The session presents a recipe for writing CATCH block where focus is on keeping things simple and you will learn why it is not a good idea to make your error handling ""fancy"", although it may seem to be a good idea in theory. The session also covers a few things to think of on client level.

SQL FRIDAY #50 - Markus Ehrenmüller-Jensen on 'From SQL to R – Leverage Your T-SQL Knowledge to Learn R'
You are already familiar with T-SQL and are eager to learn R but do not know, where to start? Start from what you already know: T-SQL. Both languages have many things in common on some levels, but are very different on others. This session will kick you off to the new language by using analogies from T-SQL. You will learn how to write your first R-scripts, make usage of packages and will leave this session with a basic understanding of typical use-cases of R and how to integrate that into your existing environment with SQL Server.
