Workaround Description:
Use an inline view the project the aggregate expressions as columns. For example, instead
of
"SELECT (SELECT X FROM Y WHERE Z = MAX(A)) FROM B GROUP BY C"
use
"SELECT (SELECT X FROM Y WHERE Z = MAX_A) FROM (SELECT MAX(A) AS MAX_A FROM B GROUP
BY C) AS VW"

issues with correlation and aggregation

Key: TEIID-1680
URL: https://issues.jboss.org/browse/TEIID-1680
Project: Teiid
Issue Type: Bug
Components: Query Engine
Affects Versions: 7.0
Reporter: Steven Hawkins
Assignee: Steven Hawkins
subqueries used in the having/select clause of a query with grouping only understand
correlated element symbols - not correlated grouping expressions or correlated aggregate
values.
If a nested aggregate contains only outer references, then it should be treated as a
correlated value.
