But that would be up to the class implementing ResultSetHandler. Having the operation in the interface would simply allow a caller to get an instance of some ResultSetMetaData, however the implementing class handler choses to provide it. In the test I wrote, I had the implementing class grab the RSMD instance from the RS as the first thing done in the handle method, and the instance of RSMD returned by the RS was intact after the RS was closed.
