using condition on more than one pl sql blocks

Question

Is it possible to use one condition on more than one pl sql blocks instead of repeating some condition in all blocks ? for example something like this :

BEGIN  
     select user_id from users  
     if :app_user_id = user_id  
         then do the bottom blocks  
     begin  
     end ;  
     begin  
     end ;  
     begin  
     end ;  
END ;

Answer 1

As per my understanding of the question, you need to check a condition at different points in your code.

You could put that one condition in a procedure/function (depending upon your code) and execute the same rather than putting down those conditions again and again.

Please correct me if my understanding is wrong.

Answer 2

It is possible, why wouldn't it be?

I don't know how wise it is (what you accomplish with two consecutive execution blocks at the same level, which you couldn't accomplish in a single block instead), but possible it is. For example:

begin
  if 3 > 1 then
    begin
      dbms_output.put_line('First line');
    end;
    begin
      dbms_output.put_line('Second line');
    end;
  end if;
end;
/

Output (obviously, SET SERVEROUTPUT ON first, if not already on):

First line
Second line
