> Take an example of the field FIELDSOFSIMPLEINTERFACE.SIMPLEINTERFACE40. This is a field of type SimpleInterface with no "serialized" or "embedded" attribute. The column is of type "LONG VARCHAR FOR BIT DATA". 
> A plain interface field like this should be treated as an FCO, and JPOX does this as a 1-1 relation with a FK to the other object (if the interface has more than 1 possible implementation then that field will have 1 FK column for each possible implementation). See http://www.jpox.org/docs/1_1/interfaces.html. As a result the column should be of type BIGINT.
> There are likely many columns on this table that are incorrect. Why is LONG VARCHAR FOR BIT DATA being used ?
