-------------------------------------
Summary: RexUtil.simplify handle literal comparison simplification
Key: CALCITE-1668
URL: https://issues.apache.org/jira/browse/CALCITE-1668
Project: Calcite
Issue Type: Improvement
Components: core
Reporter: Kevin Risden
Assignee: Julian Hyde
Priority: Minor
>From the calcite-dev mailing list:
Calcite doesn't seem to optimize away the literal comparison literal case
with RexUtil.simplify. In my understanding any literal comparison literal
results in a simple TRUE/FALSE result.
I'm not sure this is valid in the general case, but I put together a simple
example of doing this on the RexUtil simplifyCall.
