ORA-22292

Error: ORA-22292: Cannot open a LOB in read-write mode without a transaction

Causa: An attempt was made to open a LOB in read-write mode before a transaction was started.

Acción: Start a transaction before opening the LOB in read-write mode. Ways to start a transaction include issuing a SQL DML or SELECT FOR UPDATE command. Opening the LOB in read-only mode does not require a transaction.
