Sybase IQ and SQL Anywhere
Because Sybase IQ is
an extension of SQL Anywhere Server, a component of the SQL Anywhere® package, Sybase IQ supports
many of the same features as SQL Anywhere Server. The IQ documentation
set refers you to SQL Anywhere documentation, where appropriate.
Documentation for SQL Anywhere includes:
SQL Anywhere Server Database Administration describes how to run, manage, and configure SQL Anywhere databases. It describes database connections, the database server, database files, backup procedures, security, high availability, and replication with Replication Server®, as well as administration utilities and options.
SQL Anywhere Server Programming describes how to build and deploy database applications using the C, C++, Java, PHP, Perl, Python, and .NET programming languages such as Visual Basic and Visual C#. This book also describes a variety of programming interfaces such as ADO.NET and ODBC.
SQL Anywhere Server SQL Reference provides reference information for system procedures, and the catalog (system tables and views). It also provides an explanation of the SQL Anywhere implementation of the SQL language (search conditions, syntax, data types, and functions).
SQL Anywhere Server Usage describes how to design and create databases; how to import, export, and modify data; how to retrieve data; and how to build stored procedures and triggers.
You can also refer to the SQL Anywhere documentation in the SQL Anywhere Studio 11.0 collection at Product Manuals and in DocCommentXchange.
Documentation for Sybase Software Asset Management (SySAM) includes:
Sybase Software Asset Management (SySAM) 2 introduces asset management concepts and provides instructions for establishing and administering SySAM 2 licenses.
SySAM 2 Quick Start Guide tells you how to get your SySAM-enabled Sybase product up and running.
FLEXnet Licensing End User Guide explains FLEXnet Licensing for administrators and end users and describes how to use the tools that are part of the standard FLEXnet Licensing distribution kit from Sybase.

This documentation uses the following syntax conventions in syntax descriptions:
Keywords SQL keywords are shown in UPPER CASE. However, SQL keywords are case insensitive, so you can enter keywords in any case you wish; SELECT is the same as Select which is the same as select.
Placeholders Items that must be replaced with appropriate identifiers or expressions are shown in italics.
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.
Optional portions Optional portions of a statement are enclosed by square brackets. For example:
RELEASE SAVEPOINT [ savepoint-name ]
It indicates that the savepoint-name is optional. The square brackets should not be typed.
Options When none or only one of a list of items must be chosen, the items are separated by vertical bars and the list enclosed in square brackets. For example:

Sybase IQ includes scripts to create a demo database (iqdemo.db). Many of the queries and code samples in this document use the demo database as a data source.
The demo database contains internal information about a small company (employees, departments, and financial data), as well as product (products), and sales information (sales orders, customers, and contacts).
See the Sybase IQ installation guide for your platform or talk to your system administrator for more information about the demo database.
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 15.1 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.
The online help for the Sybase IQ plug-in for Sybase Central, which you can navigate using a screen reader, 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.
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.
