This book is a result of many people's efforts and we would like to thank the following individuals for their contributions.
Serge Rielau and Gustavo Arocena from DB2 development provided tremendous support and technical guidance on almost every topic we covered in the book. Their continuous support since the first edition of this book greatly helped us in verifying the content and providing insight to SQL PL.
