在oracle中使用scheduler的范例
Sql代码
-- 创建新表
create table T_TEST_JOB

ID LONG,
TEST_DATE TIMESTAMP(6)
)
tablespace GBIAPS
pctfree 10
initrans 1
maxtrans 255
storage
(
initial 64
minextents 1
maxextents unlimited
);
-- 创建序列
create sequence SEQ_TEST_JOB
minvalue 1
maxvalue 9999999999999999999999999999
start with 1
increment by 1
cache 10;
-- 创建存储过程
create or replace procedure P_TEST_JOB as
begin
insert into t_test_job(id,test_date) values (SEQ_TEST_JOB.NEXTVAL,sysdate);

/*
在使用create_job或者create_schedule前,请先检查 NLS_DATE_LANGUAGE, NLS_DATE_FORMAT,
NLS_TIMESTAMP_FORMAT, NLS_TIMESTAMP_TZ_FORMAT 等参数的值, 通过alter session 命令来修改
alter session set NLS_DATE_FORMAT='yyyy-MM-dd';
alter session set NLS_TIMESTAMP_FORMAT='yyyy-MM-dd hh24:mi:ss';
alter session set NLS_TIMESTAMP_TZ_FORMAT='yyyy-MM-dd HH:MI:SS.FF AM TZR';

-- 创建job
-- FREQ 用来指定间隔的时间周期,可选参数有: YEARLY, MONTHLY, WEEKLY, DAILY, HOURLY, MINUTELY, SECONDLY
-- INTERVAL 用来指定间隔的频繁,可指定的值的范围从1-999
-- 附加的参数有: BYMONTH,BYWEEKNO,BYYEARDAY,BYMONTHDAY,BYDAY,BYHOUR,BYMINUTE,BYSECOND
/*
每周的1,3,5运行job FREQ=WEEKLY; BYDAY=MON,WED,FRI
