TL;DR: SQL for Smarties as discussed by the authors was the first book devoted explicitly to the advanced techniques needed to transform an experienced SQL programmer into an expert, and it is the only book written by a SQL master that teaches programmers and practitioners to become SQL masters themselves.
Abstract: SQL for Smarties was hailed as the first book devoted explicitly to the advanced techniques needed to transform an experienced SQL programmer into an expert. Now, 20 years later and in its fifth edition, this classic reference still reigns supreme as the only book written by a SQL master that teaches programmers and practitioners to become SQL masters themselves! These are not just tips and techniques; also offered are the best solutions to old and new challenges. Joe Celko conveys the way you need to think in order to get the most out of SQL programming efforts for both correctness and performance. New to the fifth edition, Joe features new examples to reflect the ANSI/ISO Standards so anyone can use it. He also updates data element names to meet new ISO-11179 rules with the same experience-based teaching style that made the previous editions the classics they are today. You will learn new ways to write common queries, such as finding coverings, partitions, runs in data, auctions and inventory, relational divisions and so forth. SQL for Smarties explains some of the principles of SQL programming as well as the code. A new chapter discusses design flaws in DDL, such as attribute splitting, non-normal forum redundancies and tibbling. There is a look at the traditional acid versus base transaction models, now popular in NoSQL products. Youll learn about computed columns and the DEFERRABLE options in constraints. An overview of the bi-temporal model is new to this edition and there is a longer discussion about descriptive statistic aggregate functions. The book finishes with an overview of SQL/PSM that is applicable to proprietary 4GL vendor extensions.New to the 5th Edition: Downloadable data sets, code samples, and vendor-specific implementations!Overview of the bitemporal modelExtended coverage of descriptive statistic aggregate functionsNew chapter covers flaws in DDLExamination of traditional acid versus base transaction modelsReorganized to help you navigate related topics with easeExpert advice from a noted SQL authority and award-winning columnist Joe Celko, who served on the ANSI SQL standards committee for over a decadeTeaches scores of advanced techniques that can be used with any product, in any SQL environment, whether it is SQL 92 or SQL 2011 Offers tips for working around deficiencies and gives insight into real-world challenges
TL;DR: This contribution embraces the definition of the flexible querying language SQLf2 according to those characteristics contemplated in the norms SQL2 that can be susceptible to a fuzzy treatment.
Abstract: Traditional information storage and recovery systems are based on classic logic and set theory, limiting the user when he wants to express preferences. Fuzzy logic has been proposed for information representation and manipulation in databases, being the current tendency to study mechanisms of flexible querying to traditional databases. SQLf has been one of the efforts in this tendency. On the other hand, there are many different dialects of SQL. There are two major standards: ANSI (American National Standards Institute) SQL and an updated standard adopted in 1992, called SQL-92 or SQL2. This paper looks for to continue the contribution in the area flexible querying to relational databases. Basically this contribution embraces the definition of the flexible querying language SQLf2 according to those characteristics contemplated in the norms SQL2 that can be susceptible to a fuzzy treatment.
TL;DR: The SQL-92 query and view extensions are described and a number of issues that arose on the way to the implementation that is currently running on top of the ObjectStore OODB system are discussed.
Abstract: This paper describes the design and implementation of a query engine that provides extended SQL-based access to the data managed by an object-oriented database system. This query engine allows extended SQL queries to be embedded in C++ programs or issued interactively as from a command line interface. The language supported by the engine is the complete SQL-92 select statement plus object extensions for navigating along paths and embedded structures, querying nested sets, and invoking member functions. In addition, an object-oriented SQL view facility is provided. Using this view facility, one can define object-oriented views; one can also define views that flatten complex OODB schemas, allowing direct access by existing tools designed to provide remote access to relational databases. The view facility also supports the definition of views that include reference and set-valued columns based on other views, thus allowing entire "view schemas" to be created. This paper describes the SQL-92 query and view extensions and discusses a number of issues that arose on the way to the implementation that is currently running on top of the ObjectStore OODB system.
TL;DR: The type system of SQL3 is based on concepts such as abstract data types, object identity, polymorphism, subtypes-supertypes, parameterized types, dynamic binding, etc.
