SQL Anywhere presents tables to a client application as if all the data in the tables were stored in the database to which the application is connected. Internally, when a query involving remote tables is executed, the storage location is determined, and the remote location is accessed so that data can be retrieved.
To manage remote table mappings and remote server definitions, you can use Sybase Central or you can use a tool such as Interactive SQL to execute the SQL statements.
Some remote servers, such as Microsoft Access, Microsoft SQL Server, and Sybase Adaptive Server Enterprise do not preserve cursors across COMMITs and ROLLBACKs. With these remote servers, you cannot use the Data tab in the SQL Anywhere 12 plug-in to view or modify the contents of a proxy table. However, you can still use Interactive SQL to view and edit the data in these proxy tables as long as autocommit is turned off (this is the default behavior in Interactive SQL). Other RDBMSs, including Oracle, IBM DB2, and SQL Anywhere do not have this limitation.
