Tom McKinley presents SQL topics at NHMUG

Tom McKinley - Wednesday September 25, 2013

SQL routines - procedures, functions and triggers

While many developers know how to use SQL to query and process data, many are not aware that they can use SQL as a procedural language for programming business logic.

In this session, we will explore the capabilities of the SQL procedural language and its usage in data-centric programming with SQL procedures, functions, and triggers.

Temp tables, good or bad idea?

Even though SQL is a powerful language for processing data sets, many developers utilize temporary tables to break a complex request into multiple, smaller steps. While solving a problem with multiple steps is a valid approach, multi-step solutions involving temporary tables can negatively impact performance.

This session will illuminate these performance issues as well as demonstrate how advanced SQL features such as Views and Common Table Expressions can be used as an alternative to deliver multi-step solutions without the performance baggage.
