NOTE: This object is an extension the DB API. It is returned whenever Oracle CLOB, BLOB and BFILE columns are fetched.
NOTE: Internally, Oracle uses LOB locators which are allocated based on the cursor array size. Thus, it is important that the data in the LOB object be manipulated before another internal fetch takes place. The safest way to do this is to use the cursor as an iterator. In particular, do not use the fetchall() method. The exception "LOB variable no longer valid after subsequent fetch" will be raised if an attempt to access a LOB variable after a subsequent fetch is detected.
