[jira] [Commented] (DERBY-7113) Index has value of column which no longer exists in the table
[ https://issues.apache.org/jira/browse/DERBY-7113?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17325107#comment-17325107 ] Richard N. Hillegas commented on DERBY-7113: The DRDA error message isn't very helpful. There might be some interesting diagnostic information in the server-side derby.log file--provided that the diagnostic logging level has been set high enough. That information might help you identify the corrupt index. At this point, I have no confidence in the integrity of your database. The problem may be as simple as not disabling file system write-caching. That would be an interesting question to ask the database administrator. > Index has value of column which no longer exists in the table > - > > Key: DERBY-7113 > URL: https://issues.apache.org/jira/browse/DERBY-7113 > Project: Derby > Issue Type: Bug > Components: Network Server >Affects Versions: 10.8.3.0 > Environment: Linux with Java 8 - 8.0.6.25 >Reporter: Geraldine >Priority: Critical > > From time to time an Index keeps a value, which has been deleted from the > underlying table. > This results in an error is the row with the value is selected. > _SELECT ID from Some.TABLE WHERE IndexedColumn= 'Remembered Value';_ > _ID_ > __ > _1680880176_ > _ERROR 0A000: The DRDA command parseSQLDIAGSTT is not currently implemented. > The connection has been terminated._ > If only the Indexed Column is selected, then the Query returns 0 rows and > produces no error - because just the index is searched. > The Query Plan shows the index being used. > Dropping and Recreating the index fixes the issue.

This is even when the corruption is in place. Also, updating the statistics for the index did not resolve the issue. The only way to fix the issue was to drop and recreate it. # Regarding the advice in the link, I cannot say 100% that all this advice is followed as I am not the admin of the system but I will share this. I'm thinking in this case, the database knows that an issue exists... i.e. the index returned something but when the actual data was searched, nothing was found. I can see from the code that it throws an exception in this case. But could it be handled better? Maybe with a message saying which index was being used ? > Index has value of column which no longer exists in the table > - > > Key: DERBY-7113 > URL: https://issues.apache.org/jira/browse/DERBY-7113 > Project: Derby > Issue Type: Bug > Components: Network Server >Affects Versions: 10.8.3.0 > Environment: Linux with Java 8 - 8.0.6.25 >Reporter: Geraldine >Priority: Critical > > From time to time an Index keeps a value, which has been deleted from the > underlying table. > This results in an error is the row with the value is selected. > _SELECT ID from Some.TABLE WHERE IndexedColumn= 'Remembered Value';_ > _ID_ > __ > _1680880176_ > _ERROR 0A000: The DRDA command parseSQLDIAGSTT is not currently implemented. > The connection has been terminated._ > If only the Indexed Column is selected, then the Query returns 0 rows and > produces no error - because just the index is searched. > The Query Plan shows the index being used. > Dropping and Recreating the index fixes the issue.

We updated our products to Java 11 a little while ago, but I have managed to
dig out an example from before that change. This is from an older version of
the same product, still with Derby 10.14.2.0 and Java 1.8_161:
