--------------------------------------

             Summary: Improve Enum fields handling in SQL.
                 Key: IGNITE-3595
                 URL: https://issues.apache.org/jira/browse/IGNITE-3595
             Project: Ignite
          Issue Type: Improvement
    Affects Versions: 1.7
            Reporter: Sergi Vladykin
             Fix For: 2.0


Currently queries like this do not work in Ignite if we use enum field on the left side and enum constant name or ordinal on the right side:

select * from A where my_enum = 'ENUM_CONST';
select * from A where my_enum = 3;

This is a huge usability issue.

We can try to solve it by contributing `User defined Value types` in H2 and implementing the special value type for Enums to handle comparison with String (convert to enum by name) and with int (convert to enum by ordinal).
