---------------------------------------
Actually this is a problem introduced by TEIID-4880 as it's converting this self join
scenario into just a table scan. I'm not sure if the logic there is not accounting
for this case or if there's a metadata issue.
salesforce self join involving implicit null check on parentid field
not working
--------------------------------------------------------------------------------
Key: TEIID-5987
URL:
https://issues.redhat.com/browse/TEIID-5987
Project: Teiid
Issue Type: Bug
Components: Salesforce Connector
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Priority: Critical
Fix For: 15.0, 13.1.2, 14.0.1
Original Estimate: 4 hours
Remaining Estimate: 4 hours
I'm not sure about the full scope of this issue. In testing TEIIDSB-213 I can see
that a query such as:
select a1.id from Account a1 inner join account a2 on a1.parentid = a2.id
which results in the source query with the implicit null check:
SELECT Id FROM Account WHERE ParentId != NULL
actually returns results, but no are expected.
The explicit non-join query query
select a1.id from Account a1 where a1.parentid is not null
result in:
SELECT Id FROM Account WHERE ParentId != NULL
but returns no results
So there is something in the join handling that is not working as expected.
