[jira] Closed: (DERBY-1812) getGeneratedKeys() returns something
weird
[ http://issues.apache.org/jira/browse/DERBY-1812?page=all ]
Daniel John Debrunner closed DERBY-1812.
----------------------------------------
Resolution: Invalid
> getGeneratedKeys() returns something weird
> ------------------------------------------
>
> Key: DERBY-1812
> URL: http://issues.apache.org/jira/browse/DERBY-1812
> Project: Derby
> Issue Type: Bug
> Components: JDBC
> Affects Versions: 10.1.3.1
> Environment: java version "1.4.2-03"
> Java(TM) 2 Runtime Environment, Standard Edition (build Blackdown-1.4.2-03)
> Java HotSpot(TM) Client VM (build Blackdown-1.4.2-03, mixed mode)
> Reporter: Stephan Fuhrmann
>
> After executing in embedded the cmd
> int count=stat.executeUpdate("INSERT INTO ...",Statement.RETURN_GENERATED_KEYS);
> the stat.getGeneratedKeys() returns a non-null ResultSet. The result set meta data says the result set has one column named "1".
> Calling first() on this result set throws an exception telling something about a cursor that can't be set ... I guess it's better to return FALSE in case of calling first, because the API doc of getGeneratedKeys says:
> "Retrieves any auto-generated keys created as a result of executing this Statement object. If this Statement object did not generate any keys, an empty ResultSet object is returned."
> An empty result set would return rs.first() == false.
