SQL & PL/SQL

Hi All,

I am new to this forum

I created a trigger, but it's not working.

DECLARE

  v_width INTEGER;

  v_height INTEGER := 0;

  v_area INTEGER := 6;

BEGIN

  v_width := v_area / v_height;

  DBMS_OUTPUT.PUT_LINE('v_width = ' || v_width);

EXCEPTION

  WHEN NO_DATA_FOUND THEN

  DBMS_OUTPUT.PUT_LINE('Division by zero');

END;

/

However I always get this error

ERROR at line 1:

ORA-01476: divisor is equal to zero

ORA-06512: at line 7

I can't debug it . I need to handle it in the right way , all exceptions should be handled.
