Hi Anoop,

VSIZE returns the number of bytes in the internal representation of expr. If expr is null, then this function returns null.
its a oracle supplied function.

Note :- This function does not support CLOB data directly. However, CLOBs can be passed in as arguments through implicit data conversion.

Regards
Ravi
