Query Testing - CLOB, LOB, etc is returning an object reference in CTC rather than returning the content of the object (content is needed for validation purposes)

Query testing is returning an object reference for CLOB, LOB, etc. In the past these were returned as a string.
They should be converted to a string so the content can be validated.

Examples:

Query: SELECT * FROM XQTDoc.BQTDocTestDocument
