This book provides the definitive description of the JDBCaA A API, the technology that enables universal data access for the JavaaA A programming language. This new edition has been updated and expanded to cover all of the JDBC 2.0 API, including the JDBC 2.0 core API and the JDBC Standard Extension API, the package that facilitates building server-side applications. Containing in-depth explanations that go beyond the specification, this complete resource pairs a step-by-step tutorial with a comprehensive reference to all of the classes and interfaces. For those new to Java technology, the book includes an introduction to the Java programming language and to SQL. It builds on this basic knowledge to walk you through creating a JDBC application-from setting up a database and establishing a connection to retrieving values from result sets and using prepared statements. In addition, the authors provide many examples along the way that demonstrate how to execute common tasks. The book proceeds to more advanced topics, focusing on the new features of the JDBC 2.0 API, including scrollable and updatable result sets, batch updates, SQL3 data types, custom mapping, and more.You will also find an introduction to working with the JDBC metadata API as well as information on rowsets, the technology that makes it possible to handle data sets from any source such as JavaBeansaA A components.
From array to XADataSource, a useful alphabetical reference provides concise but complete information on each class and interface in the JDBC API. Each entry includes an overview as well as a list and explanation of the methods and fields. A chapter on mapping SQL types and types in the Java programming language, a summary of the new JDBC 2.0 features, and a glossary complete this indispensable resource for all database programmers. 0201433281B04062001
Seth White is a member of the technical staff at Java Software, where he led the design of the JDBC 2.0 API. Maydene Fisher, a native of San Jose, California, specializes in object-oriented languages. She has experience spanning both coasts of the United States, having documented everything from complex financial models on Wall Street to Java APIs in Silicon Valley. Dr. Rick Cattell, a Distinguished Engineer at JavaSoft, led the design of the JDBC API. He is currently Chief Architect for the Java Enterprise Technologies group. He was previously responsible for SunSoft's NEO CORBA database integration and the Sun Simplify database GUI. Widely recognized for his contributions to the database field, Dr. Cattell was a cofounder of SQL Access, founder and chair of the Object Database Management Group (ODMG), and author of the first monograph on object database systems as well as more than 40 papers and 3 books. Dr. Graham Hamilton is a Distinguished Engineer at JavaSoft where he led the design of the JDBC API, the JavaOS™ standalone Java system, and the JavaBeans™ component architecture. He was previously the technical lead for the Spring distributed object-oriented operating system project at Sun, and he has written a variety of papers and patents on operating systems and distributed systems. Mark Hapner is Lead Architect for the Java 2 Platform, Enterprise Edition. He participated in the development of the JDBC API, wrote the Java Message Service specification, and co-authored the Enterprise JavaBeans specification. 0201433281AB05222003
