    Unanswered: CLOB to BLOB

    Dear Experts, Here is my situation.I have got a table that contains a CLOB column. This column stores some XML data. My requirement is to change the CLOB data type to BLOB. I am thinking of the following steps:
    1. Drop CLOB column.
    2. Alter table to define a BLOB column
    3. Load the data table.
    This table is used by both online & batch. Is there any specific instructions to be followed to perform above activities? please let me know your feedback...
