マイ手順NCHARバイナリ国語キャラクタ：

CREATE OR REPLACE PROCEDURE create_schedule(id IN VARCHAR2,ac1st IN ARCHAR2,ac2nd IN VARCHAR2,ac3rd IN VARCHAR2 ,sleeper IN VARCHAR2) 
AS 
BEGIN 
DECLARE 
    query_str VARCHAR2(512); 
    ac1 VARCHAR2(10); 
    ac2 VARCHAR2(10); 
    ac3 VARCHAR2(10); 
    slp VARCHAR2(10); 
    ac1 := 'ac1st'||id; 
    ac2 := 'ac2nd'||id; 
    ac3 := 'ac3rd'||id; 
    slp := 'sleeper'||id; 

    query_str := 'alter table schedule
