It teaches all of the COBOL skills that are used in this book; it is a terrific desk reference; and it is the perfect companion to this DB2 book. To make that manageable, this book is divided into three sections. Chapter 3 shows you how to add rows to, delete rows from, and update rows in a single table. Chapter 4 shows you how to retrieve data from two or more related tables at the same time by using unions and joins. Section 2: Other programming essentials In this section, each of the seven chapters lets you expand your basic skills so you can process DB2 data with more expertise.

To get your students started right: Chapters 1 and 2 show how to retrieve data from a single DB2 table. Chapter 3 shows how to add rows to, delete rows from, and update rows in a single table. Chapter 4 shows how to retrieve data from two or more related tables at the same time by using unions and joins. In section 2, each of the seven chapters expands upon the basic skills so your students can process DB2 data with more expertise. For instance, Chapter 6 shows how to use the column functions to summarize or average the data in one column of a table.
Chapter 8 shows how to work with variable-length columns and nulls. In this section, each chapter is written as an independent unit, so you can assign these chapters in whatever sequence you prefer. In section 3, your students learn the skills for binding, precompiling, compiling, link editing, and testing COBOL programs: Chapter 12 shows how to use DB2I, which is a development tool for preparing and running DB2 programs interactively.
Chapter 13 shows how to do these programming tasks in batch, without using DB2I. You can assign the chapters in this section any time after your students complete chapter 1. What courses this book can be used for If you offer mainframe programming courses in your curriculum, this book can be used for a complete course in DB2 programming. Then, your students can compile and test their exercises and projects on that mainframe. These components provide everything that other publishers provide in a way that delivers better results.
Since that printing, errors were discovered in the programs in chapters 2 and 3. Those errors are described below. You can correct this problem using one of two techniques. Correction to Chapter 3 Page 99 In module of the enhanced update program, the SQLCODE is displayed if an error occurs during the processing of a transaction and the unit of work must be rolled back.
