Hello Tim,
It seems like a D2RQ issue. How did you delete the references to Blobs
and indices? Did you modify the mapping file?

Hi,
This may be more of D2RQ issue that TBC so I apologize in advance if
that is the case.
I've managed to connect to my database, create the mapping files,
delete the references to Blobs and indices, etc...
I can open the DataView file and see instances in the Instance view
for the various classes. However, when I try to view the instances, a
D2RQ exception is thrown that essentially displays an Oracle SQL error.
In short, the query generated by D2RQ is not valid:
de.fuberlin.wiwiss.d2rq.D2RQException: ORA-01722: invalid number
: SELECT 1 FROM "ATTRIBUTE" WHERE "ATTRIBUTE"."ATTRIBUTE_ID" =
'_TYPE10' (E0)
Of course this query will always return a value of "1" so I do not
know what D2RQ is attempting to do. Regardless, this query is invalid
since Attribute.Attribute_ID is a number column - not a character.
The schema file correctly indicates a range of xsd:decimal for this
column.
Has anyone seen this type of behavior from D2RQ before?
Thanks,
Tim
