This preface contains these topics:
The SQL*Plus User's Guide and Reference is intended for business and technical users and system administrators who perform the following tasks:
Develop and run batch scripts
Format, calculate on, store, print and create web output from query results

Our goal is to make Oracle products, services, and supporting documentation accessible, with good usability, to the disabled community. To that end, our documentation includes features that make information available to users of assistive technology. This documentation is available in HTML format, and contains markup to facilitate access by the disabled community. Accessibility standards will continue to evolve over time, and Oracle is actively engaged with other market-leading technology vendors to address technical obstacles so that our documentation can be accessible to all of our customers.

Many of the examples in this book use the sample schemas, which are installed by default when you select the Basic Installation option with an Oracle Database installation. See Oracle Database Sample Schemas for information on how these schemas were created and how you can use them yourself.
SQL*Plus error message documentation is available in SQL*Plus Error Messages. Oracle Database error message documentation is only available in HTML. If you only have access to the Oracle Database Documentation media, you can browse the Oracle Database error messages by range. Once you find the specific range, use your browser's "find in page" feature to locate the specific message. When connected to the Internet, you can search for a specific error message using the error message search feature of the Oracle Database online documentation.
