[ https://issues.redhat.com/browse/TEIID-5987?page=com.atlassian.jira.plugi... ] Steven Hawkins updated TEIID-5987: ---------------------------------- Description: 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 actually returns results, but no are expected. Whereas select a1.id from Account a1 where a1.parentid is not null returns no results as expected was: 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. Summary: Plan with join removal returns unexpected values (was: salesforce self join involving implicit null check on parentid field not working) -- This message was sent by Atlassian Jira (v7.13.8#713008)
