MDAC 2.5 SDK - OLE DB Providers
Cursor Service for OLE DB
The Cursor Service for OLE DB supports the interfaces listed in the following table.
| Interfaces | Description |
| IColumnsInfo | Determines basic column information such as number of columns, type, and labels. |
| IColumnsRowset | Used to retrieve extended metadata information such as BASETABLENAME, BASECOLUMNNAME, and KEYCOLUMN. |
| IDBAsynchStatus | Consumers can ask for status or cancel operations when asynchronous data source object initialization or asynchronous rowset generation or population has been requested. |
| IRowset | Base rowset interface, providing methods for fetching rows sequentially, getting the data from those rows, and managing rows. |
| IRowsetIdentity | Indicates whether row instance identity is implemented on the rowset and enables testing for row identity. This means that any two row handles representing the same underlying row will always reflect the same data and state. |
| IRowsetChapterMember | Detects whether or not a row is a member of a chapter. |
| IRowsetChange | Used to update the values of columns in existing rows, delete existing rows, and insert new rows. |
| IRowsetInfo | Provides information about a rowset. |
| IRowsetResynch | Discards the entire row and any changes to that row. |
| IRowsetScroll | Enables consumers to fetch rows at approximate positions in the rowset. |
| IRowsetUpdate | Enables consumers to delay the transmission of changes made with IRowsetChange to the data store. For specific information about the available methods, see: |
| IParentRowset | Used to retrieve child rowsets from a hierarchical rowset. |
