Understanding proxy tables

A proxy table exists in an Adaptive Server database, like other user tables. However, unlike other user tables, the data for a proxy table exists on a remote server.

A proxy table is a user table that allows you to access data in a remote table, view, RPC, directory, or file. A proxy table has all the attributes of a user table, such as columns, indexes, triggers, and so on, but it does not contain any data locally.

Sybase Central also supports creation of proxy tables based on files and directories.

You can create proxy tables as follows:

Map a proxy table to an existing remote table or view. The columns in these tables must match the properties of the columns in the remote table or must be the Adaptive Server equivalent of the remote column. Component Integration Services treats views as if they were tables without any indexes.
Create a proxy table that maps to an RPC.The result set of the RPC is treated as a read-only table.
Create a proxy table and a remote table at the same time. The columns on the remote table are created with the properties you define for the proxy table.

After you create a proxy table, you work with it as you would with any other table. For complete information about proxy tables, see Component Integration Services Users Guide.
