The AffectRecords parameter may be any one of the following TAffectRecords values:

| arCurrent | Only the updates for the current row are applied. |
| arFiltered | Only updates for rows matching the current filter are applied. |
| arAll | Updates for all rows are applied. |
| arAllChapters | Update affects all chapters (ADO chapters) |
Note: To use batch updating, the CursorType property of the dataset component must be either ctKeySet (the default) or ctStatic and the LockType property must be ltBatchOptimistic.
