Runkang He updated CALCITE-5815:
--------------------------------
Description:
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.
Note that this Jira is inspired from discussion of
[CALCITE-5733|https://issues.apache.org/jira/browse/CALCITE-5733].
