Subject [jira] Commented: (DERBY-3422) Embedded returns wrong value for DatabaseMetaData.autoCommitFailureClosesAllResultSets()
Date Mon, 25 Feb 2008 17:24:51 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3422?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12572134#action_12572134

Mamta A. Satoor commented on DERBY-3422:

Merged revision 629395 from trunk into codeline(630941). The reason for merge is
that I would like to merge changes for DERBY-3304 (629926) into trunk but that revision depends
on DERBY-3404 (629712) which depends on DERBY-3422 (629395)

> DatabaseMetaData.autoCommitFailureClosesAllResultSets() returns false both on the client
and on embedded. However, the embedded driver does in fact close all open result sets when
an error occurs in auto-commit mode. There is a test case in jdbc4.TestDbMetaData to test
this (testAutoCommitFailure), but it only uses ResultSet.isClosed() to check whether or not
the result set is closed after the failure. Because of DERBY-3404, isClosed() returns false
for the result sets that have been closed because of the failure, so the test doesn't reveal
the bug. If the test is changed to invoke methods on the result set (e.g. next()) instead
of calling isClosed(), we'll see that the result set is in fact closed and get an SQLException
with SQL state XCL16.
