Continuation Lines beginning with ... are a continuation of the statements from the previous line.
Repeating items Lists of repeating items are shown with an element of the list followed by an ellipsis (three dots). One or more list elements are allowed. If more than one is specified, they must be separated by commas.

Sybase IQ includes a sample database used by many of the examples in the IQ documentation.
The sample database represents a small company. It contains internal information about the company (employees, departments, and financial data), as well as product information (products), sales information (sales orders, customers, and contacts), and financial information (fin_code, fin_data).
The sample database is held in a file named asiqdemo.db, located in the directory $ASDIR/demo on UNIX systems and %ASDIR%\demo on Windows systems.
This document is available in an HTML version that is specialized for accessibility. You can navigate the HTML with an adaptive technology such as a screen reader, or view it with a screen enlarger.
Sybase IQ 12.7 and the HTML documentation have been tested for compliance with U.S. government Section 508 Accessibility requirements. Documents that comply with Section 508 generally also meet non-U.S. accessibility guidelines, such as the World Wide Web Consortium (W3C) guidelines for Web sites.
For information about accessibility support in the Sybase IQ plug-in for Sybase Central, see “Using accessibility features” in Introduction to Sybase IQ. The online help for this product, which you can navigate using a screen reader, also describes accessibility features, including Sybase Central keyboard shortcuts.
Configuring your accessibility tool
You might need to configure your accessibility tool for optimal
use. Some screen readers pronounce text based on its case; for example,
they pronounce ALL UPPERCASE TEXT as initials, and MixedCase Text
as words. You might find it helpful to configure your tool to announce
syntax conventions. Consult the documentation for your tool and
see “Using
screen readers” in Introduction to Sybase IQ.
For information about how Sybase supports accessibility, see Sybase Accessibility. The Sybase Accessibility site includes links to information on Section 508 and W3C standards.
For a Section 508 compliance statement for Sybase IQ, go to Sybase Accessibility.
Each Sybase installation that has purchased a support contract has one or more designated people who are authorized to contact Sybase Technical Support. If you cannot resolve a problem using the manuals or online help, please have the designated person contact Sybase Technical Support or the Sybase subsidiary in your area.
