在多个pl sql块上使用条件

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
