Subject [jira] Commented: (OPENJPA-525) Inserts new entity with NULL value for Clob column actually inserts empty string
Date Tue, 25 Aug 2009 04:01:59 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-525?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12747216#action_12747216

Amy Yang commented on OPENJPA-525:
----------------------------------

Oracle: Database 10g Enterprise Edition Release 11g
Driver: Oracle JDBC Driver version - "11.1.0.7.0-Production"

MySQL: 5.1.37-community MySQL Community Server (GPL)

branch1.1.x: r807362
TestSerializedLobs passed on oracle and mysql.
TestInputStreamLob passed on mysql. on Oracle, it's result is "Tests run: 13, Failures: 1,
Errors: 12, Skipped: 0". The failure isn't caused by the patch. It failed before r786218 too.
I think it should be tracked by OPENJPA-1248.
TestReaderLob: on oracle, the result is similar with TestInputStreamLob. The failure isn't
caused by the patch either. We should track it with OPENJPA-1248 too. I'll paste a stack trace
to that issue. 
on mysql, even before r786218, testUpdateWithNull will fail. at r807362 it also failed. I.e.
the OPENJPA-525-3-branch1.1.x.patch doesn't cause any regression. I'll create a new JIRA issue
to track the failure.

trunk: r807465+OPENJPA-525.3.patch
TestSerializedLobs: same as 1.1.x branch
TestInputStreamLob: same as 1.1.x branch.
TestReaderLob: same as 1.1.x branch

So I think OPENJPA-525.3.patch does resolve the original problem of this issue and safe to
be checked in.

Thanks,
Amy
