Enhanced descriptions from Syndetics:

franca database management; it provides the basis for systems interoperability, application portability, client/server operation, distributed database, and more, and is supported by just about every DBMS on the market today. SQL2 - or, to give it its official name, the International Standard Database language SQL (1992) - represents a major set of extensions to the earlier SQL standard. For a start, the new specification is well over 600 pages, compared with less than 100 for the original version. No database professional can afford to ignore it. Features *Thorough revision of the official ANSI standard for SQL. * Covers all important new SQL2 features including extensive integrity support, powerful new operators, national and international character data support and comprehensive date and time support. * Continues the tradition of careful, clear, and accurate explanations of complex technical material Features New to this Edition * Covers extensive integrity support, powerful new operators, national and international character data support, all features of SQL2; comprehensive date and time support and clear explanation of the complexitites of Dynamic SQL, all features of SQL2. * P

Includes bibliographical references (pages 509-512) and index.

Excerpt provided by Syndetics

Several changes have occurred in the SQL standards world since the previous edition of this book was published. First of all, a major new component, the Call-Level Interface (SQL/CLI), was added to the standard in 1995. Second, another major new component, the Persistent Stored Modules feature (SQL/PSM), is currently under development (and indeed nearing completion); SQL/PSM is not yet part of the standard but is virtually certain to become so in the near future. Third, the original standard itself has been significantly changed and corrected through the publication of two Technical Corrigenda, one in 1994 and one in 1996. Taken together, these changes are more than sufficient to justify this new (fourth) edition. At the same time, I have taken the opportunity to extend and improve the text throughout in numerous ways, and in particular to correct a few errors. It is not an exaggeration to say that scarcely a sentence survives intact from the third edition. Acknowledgments Once again I must thank my coauthorHugh Darwenfor his invaluable contribution (especially in connection with the SQL/PSM and SQL3 appendixes). I would also like to thank Paul Cotton and Frank Pellow for their help with the material on SQL/CLI; Peter Pistor for pointing out an error in the treatment of foreign keys in the previous edition; Mike Sykes for assistance with questions regarding SQL's date and time support (especially in connection with time zones); and Mel Zimowski for assistance with questions regarding SQL's "global transaction" support. I am also indebted to Nelson Mattos, Frank Pellow, and Jeff Richey for their careful reviews of the manuscript. Finally, I am (as always) deeply indebted to my wife, Lindy, for her support throughout this project; to my editor, Elydia Davis, for her usual sterling job; and to the staff at Addison-Wesley for their usual help and professionalism. Once again it has been a pleasure to work with them. Healdsburg, California C. J.
