[jira] Resolved: (DERBY-5004) Typo in column name
"HASH_KEY_COLUMN_NUMBER" in SYSXPLAIN_SCAN_PROPS system table documentation
[ https://issues.apache.org/jira/browse/DERBY-5004?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Dag H. Wanvik resolved DERBY-5004.
----------------------------------
Resolution: Fixed
Fix Version/s: 10.8.0.0
Patch committed as svn 1067455. Thanks, Nirmal.
As an aside, I noted that when searching for the string in the PDF version of the documents I didn't find it. Checking the table, I see that the columns in that format are too narrow, so only part of the identifier is shown: this affects the ability to search it too. Kim, have you noticed this? Do we have a way to fix it?
