Hints on function return¶

Function without RETURN statement¶

Editor provides errors if the return statement is missing in functions.

Example of Incorrect Code:

FUNCTION Finite_State_Events__ (  
   db_state_ IN VARCHAR2 ) RETURN VARCHAR2  
IS  
BEGIN  
   IF (db_state_ IS NULL) THEN  
      RETURN NULL;  
   ELSIF (db_state_ = 'Invalid') THEN  
      RETURN 'SetValid^';  
   END IF;  
END Finite_State_Events__;

Example of Correct Code:

FUNCTION Finite_State_Events__ (  
      db_state_ IN VARCHAR2 ) RETURN VARCHAR2  
   IS  
   BEGIN  
      IF (db_state_ IS NULL) THEN  
         RETURN NULL;  
      ELSIF (db_state_ = 'Invalid') THEN  
         RETURN 'SetValid^';  
      END IF;  
      RETURN NULL;  
   END Finite_State_Events__;

Add an IgnoreFunctionReturn marker.

Unreachable statement¶

Editor provides errors for unreachable statements in functions.

Example of Incorrect Code:

FUNCTION Finite_State_Events__ (  
      db_state_ IN VARCHAR2 ) RETURN VARCHAR2  
   IS  
   BEGIN  
      IF (db_state_ IS NULL) THEN  
         RETURN NULL;  
      ELSE  
         RETURN 'SetValid^';  
      END IF;  
      RETURN NULL;  
   END Finite_State_Events__;

Example of Correct Code:

FUNCTION Finite_State_Events__ (  
      db_state_ IN VARCHAR2 ) RETURN VARCHAR2  
   IS  
   BEGIN  
      IF (db_state_ IS NULL) THEN  
         RETURN NULL;  
      ELSIF (db_state_ = 'Invalid') THEN  
         RETURN 'SetValid^';  
      END IF;  
   END Finite_State_Events__;

Actions Available:
