Hi tony:
I guess there is no column in you table *test.t*.
This piece of code is generated by *JdbcToEnumerableConverter*.
In general, the logic extracts fields from *ResultSet*, and the catch
clause is necessary.
When the field count is 0, we can shot the issue.

There are some discussions[1] and on-going work[2] for it.

Hi Ashutosh,
We have ever encountered a similar problem when we need to support 'fake'
Hive functions in Calcite and push it down.
Our approach is to use Object.class to define functions.
e.g.
public static class Dummy {
public String trim(Object arg) {
..
}
}

I personally agree with Haisheng Yuan and Rui Wang.
Expression normalization is a common technique in many database products
and benefits to query optimizer. We should not stop the efforts in this
direction.
But in current calcite code base, even mininal changes in plan may bring
great impacts,

Hi all,
We made some optimizations in practice. But I'm not sure whether this kind
of change is necessary to the community, because it will make the code

Hi, Enrico,
I'm a little confused about your expectations. Could you clarify it?
Moreover, is it right for the below simplification (do you mean v is not
null)?
(v=1 and v is null) -> v=1
(do you mean v is not null?)

Hi，Sgybham,
According to our study, it is developed for Spark 1.x and not powerful in

Rather than relying on Spark adapter, I suggest you convert RelNode back to
