Project: Derby
Issue Type: Bug
Components: Tools
Reporter: Junjie Peng
Assignee: Junjie Peng
RuntimeStatisticsParser can not distinguish names of table or index well and
truly.
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.
