Hi, Is vertical inheritance not supported in Cayenne 3.0? According to the documentation, vertical inheritance is supported, but I am running into problems with the generated SELECT query when reading one of the subclasses:
The generated query is: SELECT t0.DATA_COLLECTION_ID, t0.COLLECTION_TYPE_ID, t0.DATA_COLLECTION_ID, t0.SCHOOL_YEAR, t0.SNAPSHOT_DATE FROM ESDM.K12_DATA_COLLECTION t0 JOIN ESDM.DATA_COLLECTION t1 ON (t0.DATA_COLLECTION_ID = t1.DATA_COLLECTION_ID) JOIN ESDM.DATA_COLLECTION_TYPE t2 ON (t1.COLLECTION_TYPE_ID = t2.COLLECTION_TYPE_ID) WHERE t2.COLLECTION_TYPE_ID = ? [bind: 1->COLLECTION_TYPE_ID:3] which is a problem because 1) column COLLECTION_TYPE_ID is in select list for the subclass (K12_DATA_COLLECTION) but that column is in the super class table (DATA_COLLECTION), not the subclass 2) DATA_COLLECTION_ID is in the K12_DATA_COLLECTION select list twice. Do you have any suggestions, or is this functionality not yet supported? thank you for any assistance you can give Julie -- View this message in context: http://cayenne.195.n3.nabble.com/Vertical-inheritance-tp827636p1334340.html Sent from the Cayenne - Dev mailing list archive at Nabble.com.
