BUG 6809176
We are on 11.1.0.6 Linux64. This Bug is with partition pruning on Interval Partitioned Tables. SQL Queries that use FFS (fast full scan) Index scans on Interval Partitioned tables can prune incorrectly and leave out whole partitions in the result set.....I.E. SQL on important tables give very wrong results.
There is an 11.1.0.6 patch for Windows Oracle but none for Linux Oracle...says upgrade to 11.1.0.7 or 11.2 (which we are doing and will take a month because we want to test 11.2 well before production.
We have added the NO_INDEX_FFS hint on various views that use partition tables and have seen this error and that works but is slower.....it also doesn't address all the SQL scripts and uses that have this issue.
