A problematic query uses the table used in the CSV tutorial:

name from depts), 'name'));
```
0: jdbc:calcite:model=src/test/resources/mode> select name from
table(dedup(cursor(select name from depts union all select name from depts),
'name'));
Error: Error while executing SQL "select name from table(dedup(cursor(select
name from depts union all select name from depts), 'name'))":
org.apache.calcite.sql.SqlBasicCall cannot be cast to
org.apache.calcite.sql.SqlSelect (state=,code=0)
