across all systems.

> the issue can be reproduced
> 1. create table myTbl1 (name varchar(1000));
> 2. create table myTbl2 (name varchar(1000));
> 3. create view myView (name) as select t1.name from myTbl1 t1 union all
> select t2.name from myTbl2 t2;
> 4. select name from myView where upper(name) in ('AA', 'BB');
> #4 failed with "org.apache.derby.impl.sql.compile.SimpleStringOperatorNode
> incompatible with org.apache.derby.impl.sql.compile.ColumnReference:
> java.lang.ClassCastException"
> If the view is created as "create myView (name) as select t1.name from myTbl1
> t1", the query worked fine.
