1、创建序列
2、创建存储过程
create or replace procedure SEQ_A_ID_RESET(v_seqname varchar2) as n number(10); tsql varchar2(100); begin execute immediate ‘select ‘||v_seqname||‘.nextval from dual‘ into n; n:=-(n-1); tsql:=‘alter sequence ‘||v_seqname||‘ increment by ‘|| n; execute immediate tsql; execute immediate ‘select ‘||v_seqname||‘.nextval from dual‘ into n; tsql:=‘alter sequence ‘||v_seqname||‘ increment by 1‘; execute immediate tsql; end SEQ_A_ID_RESET;
3、创建DBMS_JOB
begin sys.dbms_job.change(job => 3, what => ‘SEQ_A_ID_RESET(‘‘SEQ_A_ID‘‘);‘, next_date => to_date(‘18-08-2021 22:43:00‘, ‘dd-mm-yyyy hh24:mi:ss‘), interval => ‘TRUNC(sysdate,‘‘mi‘‘) + 1/ (24*60)‘); commit; end; /
