Sybase supports bookmarks and SQL bulk operations for the ODBC Driver.
Bulk insertions that use SQLBulkOperations with the option of SQL_ADD and cursor positioned updates and deletions using SQLSetPos (SQL_UPDATE, SQL_DELETE, SQL_POSITION). For instructions on using SQL_ADD and SQLSetPos, refer to the ODBC Programmer’s Reference found in the Microsoft Developer Network library at http://msdn.microsoft.com.
