Remove unnecessary inline views over group bys
----------------------------------------------
Key: TEIID-1007
URL: https://jira.jboss.org/jira/browse/TEIID-1007
Project: Teiid
Issue Type: Feature Request
Components: Query Engine
Affects Versions: 6.0.0
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Fix For: 7.0
Our check for removing a view layer only checks for a grouping node, it should check to
see if any of the projected columns are used in the group by.
e.g. instead of select max(c1) from (select c1 from table) v1 -> select max(c1) from
table
