在SQL Server和Oracle中创建job(2)-木庄网络博客

下面再看看oracle中是如何创建job的，这次我们直接使用sql脚本进行创建，一些常用的sql语句如下：

一、查看数据库中的任务

select * from user_jobs

二、删除数据库中指定的任务

begin
dbms_job.remove(50);
end;

三、创建一个每隔5分钟执行一次的任务

DECLARE
jobid NUMBER;
BEGIN
SYS.DBMS_JOB.SUBMIT(job => jobid,
what => 'BatchUpdateArchListTotalNum();', // 存储过程如果没有参数，可以省略括号，但是不能省略分号
next_date => sysdate,
interval => 'sysdate+1/24/12');
COMMIT;
END;

附：SQL server任务脚本：

USE [msdb] 
GO 
/****** 对象: Job [更新] 脚本日期: 05/12/2009 18:14:14 ******/ 
BEGIN TRANSACTION 
DECLARE @ReturnCode INT

/****** 对象: JobCategory [Database Maintenance] 脚本日期: 05/12/2009 18:14:14 ******/ 
IF NOT EXISTS (SELECT name FROM msdb.dbo.syscategories WHERE name=N'Database Maintenance' AND category_class=1) 
BEGIN 
EXEC @ReturnCode = msdb.dbo.sp_add_category @class=N'JOB', @type=N'LOCAL', @name=N'Database Maintenance' 
IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback
