------------------------------------
Summary: Decorrelator may produce different column names
Key: CALCITE-7058
URL: https://issues.apache.org/jira/browse/CALCITE-7058
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.40.0
Reporter: Mihai Budiu
In [CALCITE-7024] I have introduced an assertion (Litmus) check in the
decorrelator that the output relation type is identical to the input relation
type. This assertion is too strong, because the decorrelator sometimes produces
different column names in the result.
This may be a bug, but in the meantime it can be side-stepped by making the
check a bit weaker: the types are identical up to column names.
