> I have the following scenario mapping entity to 2 tables:
> - a mapped super class that has a field
> - a subclass with a pk and a field.
> - trying to map all the fields (except the pk (id) ) to a secondary table (SEC_TABLE2MSC)
>   - use @Column in the sub-class to override (name) to the secondary table
>   - use @AttributeOverride to override the field (street) in the mapped super class to
the secondary table.

> @MappedSuperclass

> From examining JPA spec, there is no specific in the @Column and @AttributeOverride that
this should not be allow. So I believe this is a valid scenario.
> Using the MappingTool, the attribute override does not map the street field to the SEC_TABLE2MSC
as I would expect:
> CREATE TABLE AnnMSCMultiTableEnt (id INTEGER NOT NULL, street VARCHAR(254), PRIMARY KEY
(id));
> CREATE TABLE SEC_TABLE2MSC (id INTEGER, name2 VARCHAR(254));
> CREATE INDEX I_SC_TMSC_ID ON SEC_TABLE2MSC (id);
> I experiment this a little bit and the only way I can map the street field to SEC_TABLE2MSC
is
> to add the @Column against the "street" attribute in the super class. (the commented
@Column in the example).
> The expected SQL are:
> CREATE TABLE AnnMSCMultiTableEnt (id INTEGER NOT NULL, PRIMARY KEY (id));
> CREATE TABLE SEC_TABLE2MSC (id INTEGER, street VARCHAR(254), name2 VARCHAR(254));
> CREATE INDEX I_SC_TMSC_ID ON SEC_TABLE2MSC (id);
> I tried to create the tables manually using the expected layout, but the runtime still
using the incorrect tables structure. I would suspect the MappingTool and the runtime are
using the same mapping strategy.
