[teiid-issues] [JBoss JIRA] (TEIID-2502) Oracle Struct Serialization Error

Steven Hawkins resolved TEIID-2502.
-----------------------------------

    Resolution: Done

Added the structretrieval translator property.  It can be one of OBJECT (default), COPY, ARRAY.  In the thread linked to this issue, COPY mode would address the serialization error.  ARRAY mode can be used to retrieve a value that can be utilized by the Teiid array logic (array_get, arraytable, etc.).

When additional handling is added for struct/array types in the engine we can revisit this support.

> I'm issuing a query (a simple select * from table) on a VDB's table that contains a geometric column from oracle spatial.
> I'm getting the following error in SquirrelSQL
> Error: org.teiid.net.socket.SingleInstanceCommunicationException
> SQLState:  08S01
> ErrorCode: 0
> Afterwards the connection is broken and I cannot access any other table and have to reconnect since I get:
> Error: Error Code:TEIID20013 Message:Error Code:TEIID20013 Message:java.net.SocketException: Socket closed
> SQLState:  TEIID20013
> ErrorCode: 0
> I'm trying to access a SDO table and a geometry type column, but hoped that TEIID could read it as a BLOB without caring about the real type.
> Probably it doesn't like it too much.
