Optimizing Retrieval Speed for FOCUS Data Sources

When the AUTOPATH parameter in set ON, an optimized retrieval path—that is, one in which the lowest retrieved segment is the entry point—is selected dynamically. It is equivalent to the alternate view syntax

TABLE FILE filename.fieldname



Is not indexed. Retrieval starts at the segment in which fieldname resides.

The system determines whether optimized retrieval is appropriate by analyzing the fields referenced in a request and the data source structure. For more information on the AUTOPATH parameter, see the Developing Reporting Applications manual.
