Diffrence between %type and %rowtype

-- %TYPE is used to declare a field with the same type as
-- that of a specified table's column:

DECLARE
   v_EmpName  emp.ename%TYPE;
BEGIN
   SELECT ename INTO v_EmpName FROM emp WHERE ROWNUM = 1;
   DBMS_OUTPUT.PUT_LINE('Name = ' || v_EmpName);
END;
/



-- %ROWTYPE is used to declare a record with the same types as
-- found in the specified database table, view or cursor:

DECLARE
  v_emp emp%ROWTYPE;
BEGIN
  v_emp.empno := 10;
  v_emp.ename := 'Rajani';
   v_emp.dept := 'IT';
 
END;
/
