Reid Hartenbower commented on EJB-345:
--------------------------------------

Sorry, for the second query I meant
  "select distinct object(i) from Item i, Specification s where i.container is null and i.specification = s and :key not in indices(s.properties)"
which parses but gives same 'operand should contain  1 column(s)' error

> Hi.  I have Item, Container, and Specification entities that subclass NamedThing.  NamedThing uses a compound primary key which is a two-long representation of a UUID.  Item has a @ManyToOne with Container and Specification, and Specification has a <String,String> properties map.
> Two problems, first:
>   queries like "select distinct object(i) from Item i where i.specification.properties[:key] = :value"  produce parse errors (these are the commented-out NamedQueries in Item); the complaint is '.' character after specification
>   queries like "select distinct object(i) from Item i, Specification s where i.container is null and i.specification = s and s.properties[:key] is null" in TestItem.java:61 do parse successfully but produce the exception whose stack trace is in TestItemStackTrace.txt.  The hibernate sql is in hibernate-sql-output.txt; the complaint is 'java.sql.SQLException: Operand should contain 1 column(s)'
> Thanks,
> Reid
