The problem is at the run time when I prss search button I get no output at all..
I need your help please..

end; 

I am really shocked sometimes at this forum it's like the largest Arabian forum for Oracle and yet nobody answers anyways I would really like you to explain more so I could know what's going on and don't worry I am new as well

try This Code

if :register.fromm is not null
 then
   set_block_property('register',default_where,'regdate='||:register.fromm);
end if;
end;
