Will Noble created CALCITE-4872: ----------------------------------- Summary: UNKNOWN erroneously treated as NULL Key: CALCITE-4872 URL: https://issues.apache.org/jira/browse/CALCITE-4872 Project: Calcite Issue Type: Bug Components: core Reporter: Will Noble Assignee: Will Noble
Call {{createWithNullability}} on an {{UnknownSqlType}} currently returns a {{NULL}} type. Furthermore, it's impossible to cast to unknown types, according to {{SqlTypeUtil.canCastFrom}}. This introduces a new {{SqlTypeName}} -- {{UNKNOWN}} -- which behaves like {{NULL}} in all ways except that it's no longer actually equal to {{NULL}}, and can always be cast to. -- This message was sent by Atlassian Jira (v8.3.4#803005)
