 Key: CALCITE-1544
 URL: https://issues.apache.org/jira/browse/CALCITE-1544
 Project: Calcite
  Issue Type: Bug
Reporter: Kurt Young
Assignee: Julian Hyde


Here is the sql to reproduce the failure:
{code}
select e.deptno
from sales.emp as e join sales.dept as d on e.deptno = d.deptno
group by e.deptno
{code}
After push the aggregator past join, the RowType seems been changed.

[jira] [Created] (CALCITE-1543) Decorrelator assertion fail

2016-12-15 Thread Kurt Young (JIRA) 
Kurt Young created CALCITE-1543:

 Summary: Decorrelator assertion fail
 Key: CALCITE-1543
 URL: https://issues.apache.org/jira/browse/CALCITE-1543
 Project: Calcite
  Issue Type: Bug
Reporter: Kurt Young
Assignee: Julian Hyde


Caused by: java.lang.AssertionError at 
org.apache.calcite.sql2rel.RelDecorrelator.decorrelateRel(RelDecorrelator.java:456)

The code is:
{code}
final Frame frame = getInvoke(oldInput, rel);
if (frame == null) {
  // If input has not been rewritten, do not rewrite this rel.
  return null;
}
assert !frame.corVarOutputPos.isEmpty();
{code}

Seems like it's no need to assert the corVarOutputPos because in some cases, 
the correlate has been fully rewritten.
