>                 Key: CALCITE-1543
>                 URL: https://issues.apache.org/jira/browse/CALCITE-1543
>             Project: Calcite
>          Issue Type: Bug
>            Reporter: Kurt Young
>            Assignee: Julian Hyde
>             Fix For: 1.12.0
>
>
> 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.
