-----------------------------------
Assignee: Runkang He
> Simplify 'a = MULTISET[1,2] AND a = MULTISET[2,3]' to 'FALSE'
> -------------------------------------------------------------
>
> Key: CALCITE-5815
> URL: https://issues.apache.org/jira/browse/CALCITE-5815
> 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 = MULTISET[1,2] AND a = MULTISET[2,3]
> {code}
> Since MULTISET type is comparable according to ANSI SQL standard, it would be
> nice to simplify above expression to FALSE.
