If both are supported, MFC uses:: For more information about driver requirements for dynasets, see Bj. In the MFC ODBC database classes, dynasets are recordsets with dynamic properties; they remain synchronized with the data source in certain ways.
[MySQL-odbc] ODBC Driver Does Not support Dynasets
Wednesday, June 11, 7: Alternatively, for snapshots, you can use the cursor library, which provides the required support for updateable snapshots static cursors and positioned update statements. If the driver for your data source conforms to the Level 1 API set, you can still use both updateable and read-only snapshots and forward-only recordsets, but not dynasets.

Snapshot Recordset no longer updatable http: Can you suggest us for a workaround or a probable solution for this? Keyset-driven cursors manage data from a table by getting and storing a set of keys. If this is causing problems in your application’s behavior, I suggest you check with the SQL Server forum at http: The keys are used to obtain current data from the table when the user scrolls onto a particular record. If the cursor library is used, it masks some functionality of the underlying ODBC driver that is necessary for dynaset support.
The MFC database classes support dynasets if the following requirements dymasets met. Product feedback Sign in to give documentation feedback.

The ODBC driver for your data source must support extended fetching. However, a Level 1 driver can support dynasets if it supports extended fetch and keyset-driven cursors. You also may be able to set the option on your HDBC yourself, but this may not be supported.
A cursor is a mechanism used for keeping track of its position in a recordset. Extended fetching is the ability to scroll backward as well as forward over the resulting records of your SQL query.
