Is it necessary to close an Adodb.recordset object before setting it to nothing?

set rs = ReturnARecordset \'assume ReturnARecordset does just that...

\'do something with rs

rs.Close
set rs = Nothing

Answer 1

Yes, this does more than just force a garbage collection it also tells the server the connection is being terminated, this avoids having multiple open orphaned connections (they will eventually time-out by themselves) but its always best practise to close them out.

This is especially apparent when ADODB is using a remote connection rather than a local one.
