Knut Anders Hatlen updated DERBY-4650:
--------------------------------------
Attachment: test.diff
The attached patch adds a test case to RestrictedVTITest that shows that the
predicate is not pushed in the following query:
select s_r, count(*) from table(integerList()) t group by s_r having s_r > 1
Only the rows with s_r > 1 have to be returned by the table function
integerList, so pushing the predicate could be useful.
Committed the new test case to trunk with revision 943088.
> Predicates in HAVING clause should be pushed down to restricted VTIs
