dbClearResult() returns TRUE, invisibly, for result sets obtained from both dbSendQuery()

and dbSendStatement().

Failure modes

An attempt to close an already closed result set issues a warning in both cases.


dbClearResult() frees all resources associated with retrieving the result of a query or update operation. The DBI backend can expect a call to dbClearResult() for each dbSendQuery() or dbSendStatement() call.
