Publisher's Synopsis
This is aimed at computer science and business computing undergraduates at universities and polytechnics.;SQL is the de facto standard for relatonal databases. Devised as a complete and concise guide to the relational database language SQL, this book can be used as a compendium of SQL - a combination of a User's Guide and a Reference Guide that gives not just the form of the linguistic constructs but also their meaning and multiple practical explanations. As far as possible, the SQL expresssions given in the book are constructed on the basis of the standard version of the language, a number of implementation dependent operations are expressed in ORACLE SQL due to its relative independence of any particular hardware. The standard SQL is covered in full while its extensions are given mainly to facilitate the user interface design.
