Subject [jira] Commented: (DERBY-3115) With embedded driver and autocommit, when closing a connection, updates on updatable result set are lost, unless result set is closed
Date Mon, 08 Oct 2007 16:56:50 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3115?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12533160
] 

Daniel John Debrunner commented on DERBY-3115:
----------------------------------------------

JDK 6 javadoc for Connection.close() also says that if a transaction is active at Connection.close()
time then the results are implementation defined.

So the current embedded implementation is valid, the close call fails because a transaction
is active, thus its Statement objects are not closed.

SQL Standard 17.3 GR 6) indicates that a disconnect should throw a invalid transaction state
exception (25001 though) if the connection is active.

> 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.
