PL/SQL Best Practices [15][If Statements]-Indentation

Employ indentation rigorously with IF statements to show logical levels. Each IF, THEN, ELSE, ELSIF, and END IF should align within each level. For example:
Nested IFs:

IF <condition1> 
THEN
   
ELSE
   IF <condition2> 
   THEN 
       
   ELSE  
   END IF;  
END IF;

IF with multiple ELSIFs:

IF <condition1>
THEN
   
ELSIF <condition2>
THEN
   
ELSIF <condition2>
THEN
  
END IF;
