Record Set
Different cursors available with Record set object?
In Visual Basic, explain different cursors available with Record set object?
There are four different cursor types defined in ADO:
*
Dynamic cursor Allows you to view additions, changes, and deletions by other users; allows all types of movement through the Recordset that doesn’t rely on bookmarks; and allows bookmarks if the provider supports them.
*
Keyset cursor Behaves like a dynamic cursor, except that it prevents you from seeing records that other users add, and prevents access to records that other users delete. Data changes by other users will still be visible. It always supports bookmarks and therefore allows all types of movement through the Recordset.
*
Static cursor Provides a static copy of a set of records for you to use to find data or generate reports; always allows bookmarks and therefore allows all types of movement through the Recordset. Additions, changes, or deletions by other users will not be visible. This is the only type of cursor allowed when you open a client-side Recordset object.
*
Forward-only cursor Allows you to only scroll forward through the Recordset. Additions, changes, or deletions by other users will not be visible. This improves performance in situations where you need to make only a single pass through a Recordset.
