You can't. Once the database is close, the pointer to a record content is no good.

Frankly, I suggest to review the entire database architeture of you application. You
can have multiple databases and multiple
records locked and exposd at the same time. You must remember that databases are in a
protected memory storage heap and are thus
not directely accessable all the time as if they were in one big application heap.
