我无法删除错误

第18行的错误：PLS-00103：遇到符号＆＃34; =＆＃34;什么时候期待以下之一：常数异常 table LONG_ double ref char time timestamp interval date二进制国家字符nchar

我的程序：

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 
  add( :1   number default ( :2) not null  ,
    :3 number default ( :4 ) not null  ,
    :5 number default ( :6) not null  ,
    :7 number default ( :8) not null    )';
  EXECUTE IMMEDIATE query_str using ac1,ac1st,ac2,ac2nd,ac3,ac3rd,slp,sleeper ;
commit;
END create_schedule ;

您有一些错误（BEGIN参数，DECLARE的位置，不需要的CREATE OR REPLACE PROCEDURE create_schedule( id IN VARCHAR2,ac1st IN VARCHAR2,ac2nd IN VARCHAR2,ac3rd IN VARCHAR2 ,sleeper IN VARCHAR2) AS query_str VARCHAR2(512); ac1 VARCHAR2(10); ac2 VARCHAR2(10); ac3 VARCHAR2(10); slp VARCHAR2(10); begin ac1 := 'ac1st'||id; ac2 := 'ac2nd'||id; ac3 := 'ac3rd'||id; slp := 'sleeper'||id; query_str := 'alter table schedule add( :1 number default ( :2) not null , :3 number default ( :4 ) not null , :5 number default ( :6) not null , :7 number default ( :8) not null )'; EXECUTE IMMEDIATE query_str using ac1,ac1st,ac2,ac2nd,ac3,ac3rd,slp,sleeper ; commit; END create_schedule ; /）：

request({url:formQuery(query), encoding:"utf8"}, (err, res, body) => {
    if (err) handleErr(err)
    let json = JSON.parse(body);
    console.log(JSON.stringify(json, null, 3))

})
