Constant

Description

dbUseDefaultCursor

(Default) Uses server-side cursors if the server supports them; otherwise use the ODBC Cursor Library.

dbUseODBCCursor

Always uses the ODBC Cursor Library. This option provides better performance for small result sets, but degrades quickly for larger result sets.

dbUseServerCursor

Always uses server-side cursors. For most large operations this option provides better performance, but might cause more network traffic.

dbUseClientBatchCursor

Always uses the client batch cursor library. This option is required for batch updates.

dbUseNoCursor

Opens all cursors (that is, Recordset objects) as forward-only type, read-only, with a rowset size of 1. Also known as "cursorless queries."

 

Remarks

This property setting only affects connections established after the property has been set. Changing the DefaultCursorDriver property has no effect on existing connections.
