学习在Sql Server中如何通过SQL语句创建Job
在程序中有用到
让用户自定义一些定时执行的提醒或工作任务
所以可能需要用到SQLServer相关创建的Job
因目前不熟作业创建的SQL语句
所以就
1.通过企业管理器的管理处作业的向导
直接建立一个作业
2.查看该作业的SQL语句
相关SQL语句如下
-- 2007-8-16/14:58 上生成的脚本
-- 由: sa
-- 服务器: 192.168.0.36
BEGIN TRANSACTION
DECLARE @JobID BINARY(16)
DECLARE @ReturnCode INT
SELECT @ReturnCode = 0
IF (SELECT COUNT(*) FROM msdb.dbo.syscategories WHERE name = N'[Uncategorized (Local)]') < 1
EXECUTE msdb.dbo.sp_add_category @name = N'[Uncategorized (Local)]'
-- 删除同名的警报(如果有的话)。
SELECT @JobID = job_id
FROM msdb.dbo.sysjobs
WHERE (name = N'WriteMsgOnTime')
IF (@JobID IS NOT NULL)
BEGIN
-- 检查此作业是否为多重服务器作业
IF (EXISTS (SELECT *
FROM msdb.dbo.sysjobservers
WHERE (job_id = @JobID) AND (server_id <> 0)))
BEGIN
-- 已经存在,因而终止脚本
RAISERROR (N'无法导入作业“WriteMsgOnTime”,因为已经有相同名称的多重服务器作业。', 16, 1)
GOTO QuitWithRollback
END
ELSE
-- 删除[本地]作业
EXECUTE msdb.dbo.sp_delete_job @job_name = N'WriteMsgOnTime'
SELECT @JobID = NULL
END
