    Oracle Sequence error: Cannot infer EdmType for java type: oracle.sql.ROWID

      Hi,

       

      As per the docs (Oracle Translator - Teiid 8.12 - Project Documentation Editor), we can map Oracle sequence as:

       

      "You can also use a sequence as the default value for insert columns by setting the column to autoincrement and the name in source to <element name>:SEQUENCE=<sequence name>.<sequence value>."

       

      So, my mapping is:

      Column Name: TELA_ID

      Name In source: TELA_ID:SEQUENCE=SEQ_TELA.NEXTVAL

      Autoincrement: true

       

      In my odata2 request I'm not sending the TELA_ID field, so by the debug I can confirm that teiid understands correctly the mapping and build the sentence by setting the TELA_ID and the nextval from sequence.

       

      The problem is that, when Teiid tries to retrieve the generated id from the SQL statement, the following error occurs:

       

       

      TEIID16013 Error occurred producing OData result.: java.lang.IllegalArgumentException: Cannot infer EdmType for java type: oracle.sql.ROWID

      Am I missing something? As per my understanding, the problem is that Oracle does not return the Column id as metadata (the oracle driver - ojdbc6.jar - returns oracle.sql.ROWID as the column name) and, as consequence, this error occurs.

       

      Please help.
