Call this member function to determine the persistence of bookmarks on a recordset object after certain operations.
DWORD GetBookmarkPersistence( ) const;
A bitmask that identifies the operations through which bookmarks persist on a recordset object. For details, see Remarks.
For example, if you call CRecordset::GetBookmark and then call CRecordset::Requery, the bookmark obtained from GetBookmark may no longer be valid. You should call GetBookmarkPersistence before calling CRecordset::SetBookmark.
The following table lists the bitmask values that can be combined for the return value of GetBookmarkPersistence.
|Bitmask value||Bookmark persistence|
|SQL_BP_CLOSE||Bookmarks are valid after a Requery operation.|
|SQL_BP_DELETE||The bookmark for a row is valid after a Delete operation on that row.|
|SQL_BP_DROP||Bookmarks are valid after a Close operation.|
|SQL_BP_SCROLL||Bookmarks are valid after any Move operation. This simply identifies if bookmarks are supported on the recordset, as returned by CRecordset::CanBookmark.|
|SQL_BP_TRANSACTION||Bookmarks are valid after a transaction is committed or rolled back.|
|SQL_BP_UPDATE||The bookmark for a row is valid after an Update operation on that row.|
|SQL_BP_OTHER_HSTMT||Bookmarks associated with one recordset object are valid on a second recordset.|
For more information about this return value, see the ODBC API function SQLGetInfo in the Platform SDK. For more information about bookmarks, see the article Recordset: Bookmarks and Absolute Positions (ODBC).
