SQL Anywhere® Server - SQL Reference
Views
The catalog contains system tables that link together by keys and indices. In SQL Anywhere, the system tables are hidden. However, there is a system view for each table. In some cases, a system view may also include columns from more than one system tables, in order to satisfy a commonly needed join.
The following section documents the system views. To ensure compatibility with future versions of the SQL Anywhere catalogue, make sure your applications make use of system views and not the underlying system tables, which may change.
