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).

In this book, Steven Feuerstein, widely recognized as one of the world's experts on the Oracle PL/SQL language, distills his many years of programming, writing, and teaching about PL/SQL into a set of PL/SQL language "best practices"--rules for writing code that is readable, maintainable, and efficient. Too often, developers focus on simply writing programs that run without errors--and ignore the impact of poorly written code upon both system performance and their ability (and their colleagues' ability) to maintain that code over time. Oracle PL/SQL Best Practices is a concise, easy-to-use reference to Feuerstein's recommendations for excellent PL/SQL coding. It answers the kinds of questions PL/SQL developers most frequently ask about their code: The book contains 120 best practices, divided by topic area. It's full of advice on the program development process, coding style, writing SQL in PL/SQL, data structures, control structures, exception handling, program and package construction, and built-in packages. It also contains a handy, pull-out quick reference card. As a helpful supplement to the text, code examples demonstrating each of the best practices are available on the O'Reilly web site. How should I format my code? What naming conventions, if any, should I use? How can I write my packages so they can be more easily maintained? What is the most efficient way to query information from the database? How can I get all the developers on my team to handle errors the same way? Oracle PL/SQL Best Practices is intended as a companion to O'Reilly's larger Oracle PL/SQL books. It's a compact, readable reference that you'll turn to again and again--a book that no serious developer can afford to be without.

SQL (Structured Query Language) is a standardized query language for requesting information from a database. Historically, SQL has been the choice for database management systems running on minicomputers and mainframes. Increasingly, however, SQL is being adapted to PC database systems because it supports distributed databases--databases that are spread out over several computer systems, so that several users on a local-area network can access the same database simultaneously. Although there are different dialects of SQL, it is the closest thing to a standard query language that currently exists. SQL in a Nutshell is a practical and useful command reference to the latest release of the Structured Query Language (SQL99), helping readers learn how their favorite database product supports any standard SQL command. This book presents each of the SQL commands and describes its use in both commercial (Microsoft SQL Server 2000 and Oracle 8 i) and open source (MySQL, PostgreSQL 7.0) implementations. Each command reference includes the command syntax (by vendor, if the syntax differs across implementations), a description, and informative examples that illustrate important concepts and uses. SQL in a Nutshell is more than a convenient reference guide for experienced SQL programmers, analysts, and database administrators. It's also a great learning resource for novice and auxiliary SQL users such as system administrators, users of packaged client/server products, and consultants who need to be familiar with the various SQL dialects across many platforms.

This rich and detailed look at the many Oracle tools that support XML development shows Java and PL/SQL developers how to combine the power of XML and XSLT with the speed, functionality, and reliability of the Oracle database.

Includes a CD-ROM with JDeveloper 3.1, an integrated development environment for Java developers.

SQL (Structured Query Language) is the heart of a relational database management system. It's the language used to query the database, to create new tables in the database, to update and delete database fields, and to set privileges in the database. Oracle SQL: The Essential Reference is for everyone who needs to access an Oracle database using SQL--developers, DBAs, designers, and managers. SQL is based on research dating back to the late 1960s, but its first commercial release was in the RDBMS announced by the fledgling Oracle Corporation in 1979. Since that time, every other database vendor has adopted SQL, and ANSI and the ISO have made it a standard. Although vendors diverge in their extensions to SQL, the core language is standard across vendor boundaries. Despite SQL's long history and relative simplicity, few developers and database administrators are truly masters of SQL. The constant stream of vendor enhancements, the hard-won experience in tuning SQL for best performance, and the requirements of particular operational environments mean that there is always more to learn about SQL. Oracle SQL: The Essential Reference delivers all the information needed to keep ahead of the learning curve on standard SQL and Oracle's extensions to it. This single, concise reference volume will hold its own against a stack of Oracle manuals and even yield insights and examples not available in those manuals. There are chapters on basic SQL elements (naming requirements, column types, pseudo-types, data conversion rules, operators); Data Definition Language (DDL) and Data Manipulation Language (DML); common language elements (constraints, storage clause, predicates); SQL functions; PL/SQL (including procedures, functions, and packages); SQL*Plus, and Oracle SQL optimization and tuning. The book covers Oracle 8 i, release 8.1.6.

Exercises are provided at three levels: beginner, intermediate, and expert. The workbook exercises cover all the major features of PL/SQL, including those new to Oracle8i (e.g., Java and web features, autonomous transactions, and bulk binds).You'll find chapters on: Basic language elements--variables, naming, loops, conditional and sequential control, exception handling, and records. Data structures--index-by tables, nested tables, variables arrays (VARRAYs), and object technology. Database interaction--cursors, DML and transaction management, cursor variables, and native dynamic SQL Program construction--procedures, functions, blocks, packages, database triggers, and calling PL/SQL functions in SQL. Built-in functionality--the character, date, conversion, numeric, and miscellaneous functions, and the DBMS_SQL, DBMS_PIPE, DBMS_OUTPUT, UTL_FILE, and DBMS_JOB built-in packages. Miscellaneous topics--using Java with PL/SQL, external programs, PL/SQL web development, tuning PL/SQL, and PL/SQL for DBAs.

This pocket reference provides quick reference information that will help you use SQLPlus, Oracle's interactive query tool.

This compact guide provides the jump-start Oracle developers need to make the transition from traditional programming to the development of useful Web applications for Oracle8i. Even readers who start out knowing nothing about HTML, PL/SQL, or Oracle's other tools will learn how to create simple Web applications in a matter of days. The book focuses on Oracle8i, but also covers Web development for earlier Oracle versions (Oracle8 and Oracle7). Background: The explosion in the use of the Internet and the Web has resulted in a whole new way of doing business. Developers who only yesterday were using COBOL to write accounts payable systems are now being asked to create a broad range of new Internet-based applications ranging from electronic commerce (e-commerce) Web sites to internal data warehouses to enterprise resource planning (ERP) systems. Unfortunately, the filesystem architectures of most Web systems aren't up to the task. The new breed of Web applications -- which are quickly becoming critical resources that companies need to survive -- demand a platform that provides production-quality tools for content management, application development, and application integration. And current Web techniques are inadequate in many ways. Oracle8i, Oracle's "Internet database," gives Web developers a way to build Web technology on top of a relational database, rather than on a traditional filesystem. With Oracle8i, companies can apply well understood, reliable, production-quality database methodologies to Web content management. Oracle8i also supports a wide variety of application development platforms and tools that are tightly integrated to the core database. Finally, Oracle8i supports technologies that help companies tie their Web-based applications into legacy applications. There is a lot to learn in Oracle8i. Not only does it enhance basic database features, it introduces Java and a variety of Web development tools. Oracle8i provides a soup-to-nuts platform for Web site and Web application development that extends traditional database concepts to Web content. It replaces the traditional filesystem used by most Web servers with a database management system. Many users are intimidated by the vast array of new technologies in Oracle8i. And yet, they are under pressure to use these technologies to build complex Web applications right now. This book gives such users a way to start using Oracle8i immediately to create useful Web applications. It is a concise, easy-to-read guide to the basic technologies developers need to understand in order to build Web applications. Contains: The book describes the following Web development tools: PL/SQL-- a structured programming language that combines procedural constructs and standard SQL. It offers such features as cursors, loops, conditional and sequential control statements, exception handlers, records, tables, and constructs for developing modular code (functions, procedures, and packages). PL/SQL Toolkit -- a set of PL/SQL packages supplied by Oracle for use in developing Web applications. HTML -- an ASCII-based markup language used to create Web pages. WebDB -- A software system for building, monitoring, and creating content-driven Web sites; it allows users to use a Web browser to access and store information in the Oracle8i database. Oracle Application Server (OAS) -- an extensible Web server that uses plug-in programs called cartridges to allow database-integrated Web systems to be developed in a variety of languages (e.g., PL/SQL, Java, Perl). XML -- An emerging standard for creating self-describing documents. It is similar to HTML but allows you to create your own markup tags. XML is expected to be a key technology in electronic commerce systems. The book also presents several fully realized sample Web applications that will teach you how to build such applications of your own. NOTE: Although this book touches on the Java features of Oracle8i, it doesn't cover Java development per se. Switching to Java represents an enormous change for most Oracle developers. This book provides an evolutionary path for readers who want to do useful Oracle8i Web development now, using mostly familiar tools. Additional books will provide Java training for those who have mastered these Web tools and want to take the next step.

MySQL and mSQL are popular and robust database products that support key subsets of SQL on both Linux and Unix systems. Both products are free for nonprofit use and cost a small amount for commercial use. Even a small organization or web site has uses for a database. Perhaps you keep track of all your customers and find that your information is outgrowing the crude, flat-file format you started with. Or you want to ask your web site's visitors for their interests and preferences and put up a fresh web page that tallies the results. Unlike commercial databases, MySQL and mSQL are affordable and easy to use. If you know basic C, Java, Perl, or Python, you can quickly write a program to interact with your database. In addition, you can embed queries and updates right in an HTML file so that a web page becomes its own interface to the database. This book is all you need to make use of MySQL or mSQL. It takes you through the whole process from installation and configuration to programming interfaces and basic administration. Includes reference chapters and ample tutorial material. Topics include: Introductions to simple database design and SQL Building, installation, and configuration Basic programming APIs for C, C++, Java (JDBC), Perl, and Python CGI programming with databases in C and Perl Web interfaces: PHP, W3-mSQL, Lite, and mSQLPerl

Visit the catalog page for Oracle Database Administration: The Essential RefeVisit the errata page for Oracle Database Administration: The Essential RefeDownload the supplemental electronic content for Oracle Database Administration: The Essential Refe Oracle database administration requires a vast amount of information and an ability to perform a myriad of tasks--from installation to tuning to network troubleshooting to overall daily administration. Oracle provides many tools for performing these tasks; the trick is knowing what tool is right for the job, what commands you need to issue (and when), and what parameters and privileges you need to set. And, as every DBA knows, you need to know how do all this under pressure, while you face crisis after crisis. This book provides a concise reference to the enormous store of information an Oracle DBA needs every day (as well as what's needed only when disaster strikes). It's crammed full of quick-reference tables, task lists, and other summary material that both novice and expert DBAs will use time and time again. It covers the commands and operations new to Oracle8, but also provides Oracle7 information for sites still running earlier versions. Oracle Database Administration provides two types of material: DBA tasks--chapters summarizing how to perform critical DBA functions: installation, performance tuning, preventing data loss, networking, security and monitoring, auditing, query optimization, and the use of various Oracle tools and utilities DBA reference--chapters providing a quick reference to the Oracle instance and database, the initialization (INIT.ORA) parameters, the SQL statements commonly used by DBAs, the data dictionary tables, the system privileges and roles, and the SQLPlus, Export, Import, and SQLLoader syntax The book also includes a resource summary with references to additional books, Web sites, and other online and offline resources of special use to Oracle DBAs. Oracle Database Administration is the single essential reference you'll turn to again and again. If you must choose only one book to use at the office, keep at home, or carry to a site you're troubleshooting, this will be that book.

Any organization that uses the Oracle relational database management system (RDBMS) these days needs to use multiple databases. There are many reasons to use more than a single database in a distributed database system: Different databases may be associated with particular business functions, such as manufacturing or human resources. Databases may be aligned with geographical boundaries, such as a behemoth database at a headquarters site and smaller databases at regional offices. Two different databases may be required to access the same data in different ways, such as an order entry database whose transactions are aggregated and analyzed in a data warehouse. A busy Internet commerce site may create multiple copies of the same database to attain horizontal scalability. A copy of a production database may be created to serve as a development test bed. Tunability Platform autonomy Fault tolerance Scalability Location transparency Site autonomy Introduction to Distributed Database Systems SQLNet and Net8 Configuration and Administration Distributed Database Security Designing the Distributed System Oracle's Distributed System Implementation Sample Configurations 8. Engineering Considerations Oracle Replication Architecture Advanced Replication Option Installation Basic Replication Multi-Master Replication Updateable Snapshots Procedural Replication Conflict Avoidance and Resolution Techniques In a distributed database environment, data in two or more databases is accessible as if it were in a single database. Usually, the different databases are on different servers, which may be located at the same site or a continent away. Communication between the servers takes place via SQLNet (for Oracle7) or Net8 (for Oracle8). Distributed database environments offer a number of benefits over single- database systems, including: This book describes how you can use multiple databases and the distributed features of Oracle to best advantage. It covers: Table of contents: Part I: The Distributed System Part II: Replication Part III: Appendixes Appendix A: Built-in Packages for Distributed Systems Appendix B: Scripts

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.
