Subject [jira] Updated: (DERBY-4772) Data truncation error with XPLAIN-functionality enabled
Date Fri, 13 Aug 2010 13:28:16 GMT

     [ https://issues.apache.org/jira/browse/DERBY-4772?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Kristian Waagan updated DERBY-4772:
-----------------------------------

    Attachment: derby-4771-1a-prototype_code_dump.stat

Attaching patch which causes the error when running the test lang.OrderByAndSortAvoidance.
Note that the patch uses the new PlanExporter code, and since this code is in movement you
may have to apply the patch to the exact revision used by the diff.

FYI, I ran the test like this:
java -Dderby.language.disableIndexStatsUpdate=true -Djava.security.policy="<NONE>" -cp
../classes:../tools/java/junit.jar junit.textui.TestRunner org.apache.derbyTesting.functionTests.tests.lang.OrderByAndSortAvoidance

> I suspect the error can be triggered easily in client/server, but for convenience I'll
attach the patch for the test where I see the issue.
