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

Question

Dim rs as ADODB.Recordset
set rs = ReturnARecordset \'assume ReturnARecordset does just that...

\'do something with rs

rs.Close
set rs = Nothing

Is i

Answer 1

The only reason calling Close explicitly is when you are not sure if the recordset is referenced from somewhere else in your project, usually a result of some sloppy coding.

Dim rs as ADODB.Recordset
Set rs = ReturnARecordset
...
MyControl.ObscureMethod rs
...
Set rs = Nothing

Last line is supposed to terminate the recordset instance without calling Close explicitly, unless MyControl is holding an extra reference and thus preventing normal tear-down. Calling Close on rs will make sure MyControl cannot use its reference for anything useful, crashing in flames in the meantime.
