Occasionally, there may already be a connected database row set and you want to use its connection. For instance, if a user has opened a database form. To access the same database as the row set of the form, use the connection the form is working with, not opening a second connection. For this purpose, the com.sun.star.sdb.RowSet has a property ActiveConnection that returns a connection.
