-----------------------------------
Assignee: Runkang He
> Simplify 'a = MAP[1,2] AND a = MAP[2,3]' to 'FALSE'
> ---------------------------------------------------
>
> Key: CALCITE-5814
> URL: https://issues.apache.org/jira/browse/CALCITE-5814
> Project: Calcite
> Issue Type: Improvement
> Components: core
> Affects Versions: 1.34.0
> Reporter: Runkang He
> Assignee: Runkang He
> Priority: Major
>
> Currently the following expression with const map literal is not simplified
> to FALSE:
> {code:sql}
> a = MAP[1,2] AND a = MAP[2,3]
> {code}
> Since the map type is an extension to the SQL standard, it's not clear
> whether it is comparable or not. If comparable, it would be nice to simplify
> above expression to FALSE.
> Welcome to discuss or provide some information.
