Hi Everyone,

    Actually we are planning to store XML content in the CLOB column. Initially when u insert a row into the Table the CLOB column will not hold any value. Once the process is done the CLOB column will be updated with the XML Value. So initially while inserting into the Table do we have to assign any default value for reducing the fragmentation on the tables?

Am not sure., Pls clarify.

Thanks  Ragha

Clobs are stored outside the table once they exceed 4000 bytes.

As you have said, Clobs are stored outside the table once they exceed 4000 bytes. Where does it go? As what object? Do they share the same tablespace as the base table?

regards,
Lily
