SQL & PL/SQL

Hi All,


My PL/SQL Blocks looks like this

declare
i_string :='if 3>20 then 1 else 2 end if;' varchar2(100);
begin



end;



Between begin and end i want a piece of code which executes that if statement and sends 2 as output in dbms_output.put_line since 3 is not >20 .Basically i want to know how to execute dynamic if statement.Please help

Thanks,
Preethi
