If NO_GENERATED_KEYS is specified, Statement.getGeneratedKeys should return an
empty ResultSet, not null
---------------------------------------------------------------------------------------------------------
Key: DERBY-4031
URL: https://issues.apache.org/jira/browse/DERBY-4031
Project: Derby
Issue Type: Bug
Components: JDBC
Affects Versions: 10.4.2.0, 10.3.3.0, 10.5.0.0
Reporter: Kathey Marsden
Fix For: 10.5.0.0
Currently Derby returns null from Statement.getGeneratedKeys() if the
statement is prepared or executed with Statement.NO_GENERATED_KEYS. The javadoc
says:
If this Statement object did not generate any keys, an empty ResultSet object
is returned.
so we should return an empty ResultSet for this case. It is not entirely clear
what the structure of the ResultSet and ResultSetMetaData should be. I tend to
think the following:
getConcurrency() - inherit from the parent statement
getStatement() - null
ResultSetMetaData
getColumnCount - 0
an alternative would be to have the ResultSetMetaData match the signature of
Identity_Val_local() but I think to return 0 columns makes more sense.
