[jira] [Commented] (CALCITE-4888) Unexpected `RexNode` when call `RelBuilder.in` to create an `IN` predicate with a list of varchar literals which have different length

    [ https://issues.apache.org/jira/browse/CALCITE-4888?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17443548#comment-17443548 ] 

Julian Hyde commented on CALCITE-4888:
--------------------------------------

Are you getting an error "Unexpected RexNode"? Or are you getting a RexNode that you didn't expect? If the latter, maybe Calcite is doing the right thing, and the only problem is that this is not what you expect.

This is probably a duplicate of CALCITE-4590 (or several other issues).

> when call `RelBuilder.in` to create an `IN` predicate with a list of varchar literals which have different length, generated `RexNode` are expected.
> for example, ranges parameters are `b.literal("CLERK")` and  `b.literal("A")`
> Generated `RexNode` seems to be unexpected because it would cast 'A' to char(5).
