Deconecting / connecting a db via ODBC

[Ana]

Hi,

For security reasons, in a form I'd like the following to take place when I'm
updating a field:

Disconnect the actual user (username/ password),

Connect with a different username/password execute UPDATE....

Disconnect the second user

Connect with the original username/password.

Can it be done and if so, how?

The reason is that the second user has writes rights over the first user.

TIA

Ana
