Rong Qu created DERBY-6131:
------------------------------

             Summary: select from view with "upper" and "in" does not work
                 Key: DERBY-6131
                 URL: https://issues.apache.org/jira/browse/DERBY-6131
             Project: Derby
          Issue Type: Bug
          Components: SQL
    Affects Versions: 10.8.3.0, 10.9.1.0
         Environment: windows
            Reporter: Rong Qu


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.
