If you're a programmer or database administrator who uses SQL in your day-to-day work, this popular pocket guide is the ideal on-the-job reference. You'll find many examples that address the language's complexity, along with key aspects of SQL used in IBM DB2 Release 9.7, MySQL 5.1, Oracle Database 11g Release 2, PostgreSQL 9.0, and Microsoft SQL Server 2008 Release 2. SQL Pocket Guide describes how these database systems implement SQL syntax for querying, managing transactions, and making changes to data. It also shows how the systems use SQL functions, regular expression syntax, and type conversion functions and formats. All example SQL statements in this book execute against a set of tables, with data that you can quickly download. The third edition covers important database changes, including: Oracle's support of the recursive WITH syntax, and addition of PIVOT and UNPIVOT operators Functions new to Oracle, such as LISTAGG, NTH_VALUE, and more PostgreSQL’s support of recursive WITH and some window functions DB2 syntax and datatypes, some compatible with Oracle MySQL features such as the TIMESTAMP type and the TO_SECONDS function

Common SQL functions (date, numeric, math, trigonometric, string, conversion, aggregate) Such topics as literals, NULLs, CASE expressions, datatype conversion, regular expressions, grouping and summarizing data, joining tables, and writing queries (hierarchical, recursive, union, flashback) and subqueries. Instead of presenting complex and confusing syntax diagrams, the book teaches by example, showing the SQL statements and options that readers are most like to use. All example data is available on the O'Reilly web site.

This pocket reference provides quick-reference information that will help you use Oracle's PL/SQL language. It is a companion to Steven Feuerstein and Bill Pribyl's bestselling book,Oracle PL/SQL Programming, and includes coverage of the latest version of Oracle, Oracle8i. Oracle is the most popular database management system in use today, and PL/SQL plays a pivotal role in current and projected Oracle products and applications. PL/SQL provides procedural extensions to the SQL relational database language and to an ever-growing number of Oracle development tools. It offers a myriad of data types, and such features as cursors, loops, conditional and sequential control statements, exception handlers, records, tables, and constructs for developing modular code (functions, procedures, and packages). Originally a rather limited tool, PL/SQL became with Oracle7 a mature and effective language for developers. Now, with the introduction of Oracle8, PL/SQL has taken the next step towards becoming a fully realized programming language providing sophisticated object-oriented capabilities. The book on which this pocket reference is based,Oracle PL/SQL Programming, filled a huge gap in the Oracle market, providing developers with a single, comprehensive guide to building applications with PL/SQL -- and building them the right way. That book has become the bible for PL/SQL developers who have raved about its completeness, readability, and practicality. The book is packed with strategies, code architectures, tips, techniques, and fully realized code. The second edition of the book updated the text with the new Oracle8 PL/SQL features, including object types, collections, external procedures, and large object data types and functions. The pocket reference boils down the most vital information from the large (nearly 1000 pages) book into an accessible quick reference that summarizes the basics of PL/SQL -- its block structure, fundamental language elements (e.g., identifiers, declarations, defaults), data structures (including Oracle8 objects), and statements for program control, loops, exception handling, and database access. It also covers the the basics of using Oracle's procedures, functions, and packages, and the latest features for Oracle8i.
