  The code below can run in store procedure.
  How to create a views from this code?

  DECLARE @CODE VARCHAR(10)
  SET @CODE = 'AAA'
  SELECT *
  FROM MYORDER
  WHERE @CODE BETWEEN CODEFROM AND CODETO

  Views do not accept parameters. If you must pass a parameter, then you need to continue to use a stored procedure.

  You might want to check an inline table-valued function.
  
--Create some sample data and data structure
CREATE TABLE MYORDER(
  ORDERID int,
  CODEFROM varchar(10),
  CODETO varchar(10)
)
INSERT INTO MYORDER
VALUES( 1, 'A', 'L'),
  ( 2, 'LA', 'ZZZZ')
GO

  --Create a function instead of a view to allow parameters
CREATE FUNCTION OrderWithCode(
  @CODE varchar(10)
)
RETURNS TABLE
AS
RETURN
SELECT *
FROM MYORDER
WHERE @CODE BETWEEN CODEFROM AND CODETO ;
GO

  --Use the table valued function
DECLARE @CODE VARCHAR(10);
SET @CODE = 'AAA';

  SELECT *
FROM OrderWithCode(@CODE) o;

  GO
--Clean my sandbox
DROP FUNCTION OrderWithCode;
DROP TABLE MYORDER;

  I strongly second that.  Think of them as "Parameterized Views".

  RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
  First step towards the paradigm shift of writing Set Based code:
  ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

  Change is inevitable... Change for the better is not.
