SPEAKERS: Mark Doyle (Winterthur U.S. Holdings)
DBAs now are expected to manage more information, in more environments, with less down time and fewer resources. Third-party tools have helped, but they can't keep pace with the ever-growing list of new business requirements. This presentation will discuss a set of techniques, constructs and "tricks" -- a.k.a. "Smart SQL" -- that will allow DBAs to build their own tools, and build tools that build tools, based on their own environment and the constraints they face. "Smart" SQL can make DBAs (and others) more productive and better able to handle the challenges put before them.Although "smart" SQL is presented in the context of DB2 on a z/OS mainframe computer with emphasis on DBA tasks, The techniques presented here are usable in ANY relational database management system, on ANY hardware platform, and for ANY set of tasks.Attendees are invited to bring their hardest database administration challenges, to see if these techniques can assist them in overcoming those challenges.

We will discuss the theory behind "smart" SQL; and why it works the way it does
We will look at the various TSO, ISPF, DB2I & SPUFI defaults that make creating & using "smart" SQL easy
We will look at the various SQL features, functions & constructs that make "smart" SQL possible. Including special registers, string functions (CHAR, DIGITS, RTRIM, SUBSTR & CONCAT), CASE, UNION ALL, "semi-Cartesian" joins, and "driver" tables
We will discuss the anatomy of a "smart" SQL statement, including its five main parts. We will walk through the process of turning a template into "smart" SQL
