I think this is an Oracle bug that shows up in my version of Oracle and probably Mike's. My version:

Oracle Database 10g Express Edition Release - Production

From this:


he states, "Oracle offers information regarding ORA-00907 in conjunction with FULL/LEFT OUTER joins in association with Bug 4433936.  This bug causing an ORA-00907 has been fixed in and future versions of 11g"

See this:


specifically " Bug Fixes by Category"

4433936 	ORA-907 from FULL / LEFT OUTER joins
Comment 3 John Mazzitelli 2011-04-27 14:02:35 EDT
here's a simple SQL to try:


this results in the ORA 907 exception "missing right parens"

I'm not sure if this is a bug or not, if it is I think it may be in Hibernate.  It has to do with the fact that we are using Criteria queries to pull the trait data.  The CriteriaQueryGenerator has a standard way of generating count queries like:

Select count(entity) From Entity entity Where ...

But because MeaasurementDataTrait extends MeasurmentData and MeasurementData has a composite key, this is translating into something unusual.  This is the root cause.  Now need to figure out what to do.
Comment 6 Jay Shaughnessy 2011-04-27 14:34:22 EDT
D'oh!  Looks like I was right, this is a Hibernate issue:


Comment 7 Jay Shaughnessy 2011-04-27 15:54:08 EDT
It seems like we could generate our count queries slightly differently to avoid this issue.  I don't think there is really a difference between:

Select Count( entity ) 
  From Entity entity
 Where ...


Select Count( * ) 
  From Entity entity
 Where ...

I made this change locally and things seem to be working as expected. Unless someone knows of any subtleties I think this is a valid workaround.
Comment 8 Jay Shaughnessy 2011-04-27 16:08:11 EDT
I pushed this potential workaround to master for further eval:

Bulk closing of issues that were VERIFIED, had no target release and where the status changed more than a year ago.
