Inserting into BLOB field

I know this has been asked before...

I need to perform an insert into a BLOB field. Previously my field was defined as a CLOB and there was no issue. But due to a new requirement I need to change this to a BLOB. The issue that I have now is that I cannot insert any seed data into this field with a SQL script.

Is there any way that I would be able to perform these inserts using a SQL script?

Thanks...
