MySQL is a popular and robust open source database product that supports key subsets of SQL on both Linux and Unix systems. MySQL is free for nonprofit use and costs a small amount for commercial use. Unlike commercial databases, MySQL is affordable and easy to use. This book includes introductions to SQL and to relational database theory. If you plan to use MySQL to build web sites or other Linux or Unix applications, this book teaches you to do that, and it will remain useful as a reference once you understand the basics. Ample tutorial material and examples are included throughout. This book has all you need to take full advantage of this powerful database management system. It takes you through the whole process from installation and configuration to programming interfaces and database administration. This second edition has a greatly enhanced administration chapter that includes information on administrative tools, server configuration, server startup and shutdown, log file management, database backup and restore, and database administration and repair. In addition, a new chapter on security describes data, server, and client-server security, while a chapter on extending MySQL provides an overview of MySQL internals and describes the use of MySQL user-defined functions. If you know C/C++, Java, Perl, PHP, or Python, you can write programs to interact with your MySQL database. In addition, you can embed queries and updates directly in an HTML file so that a web page becomes its own interface to the database. Managing and Using MySQL includes chapters on the programming language interfaces, and it also includes a complete reference section with specific function calls for each language. Also included in the reference section are references to the SQL language, and details of the MySQL system variables, programs, and utilities. New to the second edition is a reference to the internal MySQL tables, which will be of particular interest to those who want to work extensively with MySQL security.

If you write programs to run against an Oracle database, you spend a lot of time and mental energy writing queries to return the data your programs need. Knowledge of SQL, and particularly of Oracle's implementation of SQL, is the key to writing good queries in a timely manner. In this book, the authors share their knowledge of Oracle SQL, and show you many creative techniques that you can use to advantage in your own applications. This book shows you how to: Leverage Oracle's vast library of built-in SQL functions Query time-based data, and write joins involving date and time ranges Use Oracle SQL's hierarchical query features to deal with data best represented in a tree format Use DECODE and CASE to implement conditional logic in your queries Use Oracle's new, analytic SQL features to write ranking queries, lag and lead queries, windowing queries, and more Join data from two or more tables using the newly supported SQL92 join syntax In addition, you'll see how SQL can best be integrated with PL/SQL. You'll also learn various best practices to help you write SQL queries that perform efficiently. Precious few books on the market today go beyond discussing syntax and the barest rudiments of using Oracle SQL. This book changes that, showing you how to creatively leverage the full power of SQL to write queries in an Oracle environment.

This unique cookbook contains a wealth of solutions to problems that SQL programmers face all the time. The recipes inside range from how to perform simple tasks, like importing external data, to ways of handling issues that are more complicated, like set algebra. Authors Ales Spetic and Jonathan Gennick, two authorities with extensive database and SQL programming experience, include a discussion with each recipe to explain the logic and concepts underlying the solution.SQL (Structured Query Language) is the closest thing to a standard query language that currently exists, and Transact-SQL -- a full-featured programming language that dramatically extends the power of SQL -- is the procedural language of choice for both Microsoft SQL Server and Sybase SQL Server systems. The Transact-SQL Cookbook is designed so you can use the recipes directly, as a source of ideas, or as a way to learn a little more about SQL and what you can do with it. Topics covered include: With an abundance of recipes to help you get your job done more efficiently, the Audit logging. In addition to recipes for implementing an audit log, this chapter also includes recipes for: improving performance where large log tables are involved; supporting multiple-languages; and simulating server push. Hierarchies. Recipes show you how to manipulate hierarchical data using Transact-SQL. Importing data. This chapter introduces concepts like normalization and recipes useful for working with imported data tables. Sets. Recipes demonstrate different operations, such as how to find common elements, summarize the data in a set, and find the element in a set that represents an extreme. Statistics. This chapter?s recipes show you how to effectively use SQL for common statistical operations from means and standard deviations to weighted moving averages. Temporal data. Recipes demonstrate how to construct queries against time-based data. Data Structures. This chapter shows how to manipulate data structures like stacks, queues, matrices, and arrays. Transact-SQL Cookbook is sure to become an essential part of your library.

Access Cookbook contains a comprehensive collection of problems, solutions,and practical examples for the Access power user or programmer who is running up against some of the apparent limits of the Access user interface or of Access application development. The diverse problems and solutions presented here are of interest to Access power users and programmers at all levels, from the relatively inexperienced to the most sophisticated. Each of the book?s 14 chapters focuses on a particular topic area related to the Access environment or Access programming. Within each chapter, individual items follow a standardized format. The authors first pose the problem, and then present its solution. Finally, a discussion follows, which consists of extended analysis of the solution, an insightful examination of how Access works, or interesting programming techniques that are used in the solution but that you can also apply elsewhere. The kinds of problems posed and solved in the book include the following: Specifying query criteria at runtime, rather than at design time Restricting the user to a single row of a form Preventing a report from printing if it has no records Making slow forms run faster Insuring that user interface objects present a uniform, consistent appearance Controlling a printer's paper source programmatically Referencing data from multiple SQL Server databases in a single Access Data Project page Using contact information from an Access database when sending email using Outlook The accompanying CD-ROM includes Access databases that contain the solutions for all problems presented in the text.

Access Database Design & Programming takes you behind the details of the Access interface, focusing on the general knowledge necessary for Access power users or developers to create effective database applications. When using software products with graphical interfaces, we frequently focus so much on the interface that we forget about the general concepts that allow us to understand and use the software effectively. In particular, this book focuses on three areas: Unlike other Access books that take the long, detailed approach to every topic of concern to Access programmers, Database design. The book provides an enjoyable, informative overview of database design that carefully shows you how to normalize tables to eliminate redundancy without losing data. Queries. The book examines multi-table queries (i.e.,various types of joins) and shows how to implement them indirectly by using the Access interface or directly by using Access SQL. Programming. The book examines the VBA integrated development environment (IDE). It then goes on to provide an excellent introduction to Data Access Objects (DAO), ActiveX Data Objects (ADO), and ADO Extensions for Data Definition and Security (ADOX). These sections serve as a handy introduction and primer for basic database operations,such as modifying a table under program control, dynamically adding and deleting a record, and repositioning a record pointer. The concluding chapter focuses on common programming problems, such as computing running sums and comparing two sets. Access Database Design &Programming instead focuses on the core concepts, enabling programmers to develop solid, effective database applications. This book also serves as a 'second course' in Access that provides a relatively experienced Access user who is new to programming with the frequently overlooked techniques necessary to develop successfully in the Microsoft Access environment.Anyone interested in learning Access in depth, rather than just scraping the surface, will enjoy and benefit immensely from reading this book.

One of the most important challenges faced by Oracle database administrators and Oracle developers is the need to tune SQL statements so that they execute efficiently. Poorly tuned SQL statements are one of the leading causes of substandard database performance and poor response time. SQL statements that perform poorly result in frustration for users, and can even prevent a company from serving its customers in a timely manner. In this book, Mark Gurry shares his in-depth knowledge of Oracle's SQL statement optimizers. Mark's knowledge is the result of many hard-fought tuning battles during his many years of providing Oracle tuning services to clients. Mark provides insights into the workings of the rule-based optimizer that go well beyond what the rules tell you. Mark also provides solutions to many common problems that occur with both the rule-based and cost-based optimizers. In addition to the specific problem/solution scenarios for the optimizers, Mark provides a number of handy SQL tuning tips. He discusses the various optimizer hints, telling you when they can be used to good effect. Finally, Mark discusses the use of the DBMS_STATS package to manage database statistics, and the use of outlines to specify execution plans for SQL statements in third-party applications that you can't otherwise modify.

"This is a book that deserves a prominent place by anyone who aspires to be a real professional developer of SQL Server applications." --from the Foreword by Ron Soukup The message of this book is that building stored procedures in Transact-SQL is very much like building programs in any other language. It requires the same type of skill, planning, attention to detail, and overall grasp of technology that successful development in other languages requires. To master Transact-SQL, one must first master the fundamental concepts of software development, then build on this foundation by embracing and studying Transact-SQL as a programming language in its own right. This book teaches you how to do that and more. More than just a catalog of coding tricks and syntax subtleties, explores the philosophy of Transact-SQL programming. It teaches readers how to apply this philosophy in order to develop their own coding techniques and discover their own solutions to real-world programming problems. A follow-up to the widely acclaimed The Guru's Guide to SQL Server(TM) Stored Procedures, XML, and HTML The Guru's Guide to Transact-SQL, this book teaches that stored procedure development does not occur in a vacuum--it involves a wide variety of skills, subjects, and technologies--and helps the reader become a better software engineer, not just a stored procedure expert. Blending theoretical detail with practical application, this comprehensive reference begins with a foundational overview of SQL Server(TM) stored procedure programming. From there, the focus moves on to best practices and design considerations before progressing to advanced topics and a general philosophy of software craftsmanship. In all, this book provides the most complete coverage of SQL Server stored procedure programming available in one source. Topics such as user-defined functions, views, triggers, extended procedures, error handling, OLE Automation, database design, and XML are covered in detail. The book spotlights undocumented language features and brings the first application of design patterns to the SQL language. The preview of .NET and a groundbreaking approach to adding arrays to Transact-SQL make for the most thorough and engaging read published to date on SQL Server programming. The accompanying CD-ROM contains the book's source code. More than 700 SQL scripts, programming utilities, and extended procedures provide a veritable treasure trove of high-quality example code. Theoretically sound, yet immensely practical, provides developers with the tools they need to become expert stored procedure programmers and better software engineers.

SQL Loader is a ubiquitous tool in the Oracle world. It has been shipped with Oracle since at least Version 6 and continues to be supported and enhanced with each new version of Oracle, including Oracle8 and Oracle8Loader is to load data from flat files into an Oracle database. It's optimized for loading large volumes of data, and is flexible enough to handle virtually any input format.Almost every Oracle user has to use SQL i. The job of SQL Loader at one time or another, and DBAs are frequently called upon to load data for the users in their organization. Despite SQLLoader's wide availability and usage, few DBAs and developers know how to get the most out of it. Oracle SQL has everything you need to know to put SQLLoader to its best use: an introduction to SQL Loader: The Definitive Guide Loader, a reference to all of its syntax options, and most importantly, step-by-step instructions for all the SQLLoader tasks you'd want to perform--and maybe some you didn't realize you COULD perform.You'll learn how to construct the necessary control files and load from different types of files containing different types of data (e.g., fixed-width data, delimited data, and data of various datatypes). You'll also learn how to validate data, load it selectively, transform it as it is loaded, and recover after failure. This book explains how to optimize SQL Loader performance by adjusting the transaction size and using the new direct path option. It also covers the newest SQLLoader features--the loading of large object (LOB) columns and the new object types (nested tables, varying arrays, and object tables). Oracle SQL is an indispensable resource for anyone who is new to SQLLoader; a task-oriented learning tool for those who are already using it; and a quick reference for every user. If you want to take best advantage of an essential Oracle tool, you need this book. Loader: The Definitive Guide
