Each access path initially contains all of the relations for the file on which it is based, but none of the virtuals. If you add a new relation to a file, the effect on the access path is controlled by the Automatic Add setting. Following are the three Auto Add settings:
|
Setting |
Description |
|
*Attr Only |
Only attributes are added (physical file changes). |
|
*All |
Both virtuals and attributes are added. |
|
*Held |
No changes are made to the access path. This prevents level checking. |
