Daniel John Debrunner commented on DERBY-3115:
----------------------------------------------
Michelle> To end the transaction in autocommit mode, the objects must be closed.
By "objects" I assume you mean ResultSets, the closing of the Statement is not
required to auto-commit a transaction. The rules are in JDBC 4 section 10.1.
However, closing the ResultSets is not sufficient for CallableStatements, see
section 10.1 of JDBC 4.
It indicates that the ResultSets must be closed *and* the update counts and
output parameters must be fetched. It's unclear what happens if the update
counts and output parameters are not fetched though.
> With embedded driver and autocommit, when closing a connection, updates on
> updatable result set are lost, unless result set is closed

> Key: DERBY-3115
> URL: https://issues.apache.org/jira/browse/DERBY-3115
> Project: Derby
> Issue Type: Bug
> Components: JDBC
> Affects Versions: 10.3.1.4
> Reporter: Dag H. Wanvik
> Attachments: Main.java
>
>
> With autocommit, if an application neglects to close the result set
> and/or the statement, the closing of the connection will lose any
> updates performed via an updatable result set.
> If autocommit is false, SQL state 25000 invalid transaction state will
> be thrown, however.
> The JDBC standard requires that statements be closed when the
> connection is closed, cf. JDBC 4, section 9.4.4: "All Statement
> objects created from a given Connection object will be closed when the
> close method for the object is called." For updatable result sets,
> closing the statement would lead to a closing of the result set, and
> hence a commit of the updates.
> For the network client it works as expected.
