创建存储过程

create or replace procedure pro_updatetdwjkssccs(v_czlx varchar2) is
  init number;
begin

  update t_dw_jks  a set sccs=0  where userid='123456' and fsfcs='F';
  commit;
 
end pro_updatetdwjkssccs;

创建job

declare job number;
begin
  sys.dbms_job.submit(job => job,
                      what => 'begin pro_updatetdwjkssccs(''0''); end;',
                      next_date => to_date('10-11-2018', 'dd-mm-yyyy'),
                      interval => 'TRUNC(sysdate+1)+(0*60)/(24*60)');
  commit;
end;
/

begin
  sys.dbms_job.submit(job => :job,
                      what => 'begin pro_t_pay_app_user(''0''); end;',
                      next_date => to_date('23-09-2019', 'dd-mm-yyyy'),
                      interval => 'TRUNC(sysdate)+((to_char(sysdate,''hh24'')+1)*60)/(24*60)');
  commit;
end;
/

 

删除运行的job

select * from Dba_Scheduler_Running_Jobs
select SID,SERIAL# from V$Session WHERE SID='691'
alter system kill session '691,3244';

单独授权表

grant select,insert,update,delete,all on sys_table to testdba_new
 

截取

格式1： substr(string string, int a, int b);
格式2：substr(string string, int a) ;
解释：

格式1
1、string 需要截取的字符串
2、a 截取字符串的开始位置（注：当a等于0或1时，都是从第一位开始截取）
3、b 要截取的字符串的长度
格式2
1、string 需要截取的字符串
2、a 可以理解为从第a个字符开始截取后面所有的字符串。

select
substr('2019-09-09 15:00:03', 0, instr('2019-09-09 15:00:03', ' ')-1) as code,
substr('2019-09-09 15:00:03', instr('2019-09-09 15:00:03', ' ')+1) as name
