[jira] Resolved: (DERBY-3831) RuntimeStatisticsParser can not
distinguish names of table or index well and truly
[ https://issues.apache.org/jira/browse/DERBY-3831?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Myrna van Lunteren resolved DERBY-3831.
---------------------------------------
Resolution: Fixed
Fix Version/s: 10.5.0.0
Derby Info: (was: [Patch Available])
This was a good find, thx...
However, when I ran the tests that use the modified methods in RuntimeStatisticsParser:
...lang.UpdateStatisticsTest
...lang.PredicatePushdownTest and the newly added
...lang.OptimizerOverridesTest
I got a failure in PredicatePushdownTest on the usedIndexRowToBaseRow method. The runtimestatistics output actually never shows a space in that line after the tablename, but a : (colon).
I modified that method to look for a colon after the table name and committed the change with revision 685733.

> i.e. there are two indexes t1_c1c2 and t1_c1 on table t1. Execute "select * from t1 --DeRbY-pRoPeRtIeS index = t1_c1c2" on t1. Then,RuntimeStatisticsParser.usedSpecificIndexForIndexScan("T1","T1_C1C2") will return true, while RuntimeStatisticsParser.usedSpecificIndexForIndexScan("T1","T1_C1") will return true too. It's not correct.
> The similar errors also exist on usedIndexScan(), usedIndexRowToBaseRow(), usedDistinctScan() and usedTableScan() in the class of RuntimeStatisticsParser.
