Hi All,

         the following function gives invalid lob locator specified.
         b has been initialized to empty_clob()
                  
         begin
         dbms_lob.copy(a,b,DBMS_LOB.GETLENGTH(b),1,1)  
        exception
        when others then
        dbms_output.put_line('error');
        end;

        Is the error occuring because b is empty_clob() ?
        if yes then how to check b for empty_blob in  if condition
        so that I can also initialize variable a to empty_clob()

Thanks
Manoj
