通过编程添加自动化作业
有时候看一些程序，他们在安装的时候，会在SQL Server里面创建一些特定的作业，以便为其执行自动化任务。我就在想，这是怎么做到的呢？我们以前一般都是通过SSMS的界面来完成这个事情的
1. 通过T-SQL的方式，基本上几个步骤：add_job,add_job_step,add_job_schedule,add_job_server
USE [msdb] --所有的作业信息都是存储在msdb数据库的
GO

2. 通过SMO的方式
这里有一个完整的介绍

//Connect to the local, default instance of SQL Server.
{
Server srv = default(Server);
srv = new Server();
//Define an Operator object variable by supplying the Agent (parent JobServer object) and the name in the constructor.
Operator op = default(Operator);
op = new Operator(srv.JobServer, "Test_Operator");
//Set the Net send address.
op.NetSendAddress = "Network1_PC";
//Create the operator on the instance of SQL Server Agent.
op.Create();
//Define a Job object variable by supplying the Agent and the name arguments in the constructor and setting properties.
Job jb = default(Job);
jb = new Job(srv.JobServer, "Test_Job");
//Specify which operator to inform and the completion action.
jb.OperatorToNetSend = "Test_Operator";
jb.NetSendLevel = CompletionAction.Always;
//Create the job on the instance of SQL Server Agent.
jb.Create();
//Define a JobStep object variable by supplying the parent job and name arguments in the constructor.
JobStep jbstp = default(JobStep);
jbstp = new JobStep(jb, "Test_Job_Step");
jbstp.Command = "Test_StoredProc";
jbstp.OnSuccessAction = StepCompletionAction.QuitWithSuccess;
jbstp.OnFailAction = StepCompletionAction.QuitWithFailure;
//Create the job step on the instance of SQL Agent.
jbstp.Create();
//Define a JobSchedule object variable by supplying the parent job and name arguments in the constructor.
JobSchedule jbsch = default(JobSchedule);
jbsch = new JobSchedule(jb, "Test_Job_Schedule");
//Set properties to define the schedule frequency, and duration.
jbsch.FrequencyTypes = FrequencyTypes.Daily;
jbsch.FrequencySubDayTypes = FrequencySubDayTypes.Minute;
jbsch.FrequencySubDayInterval = 30;
TimeSpan ts1 = default(TimeSpan);
ts1 = new TimeSpan(9, 0, 0);
jbsch.ActiveStartTimeOfDay = ts1;
TimeSpan ts2 = default(TimeSpan);
ts2 = new TimeSpan(17, 0, 0);
jbsch.ActiveEndTimeOfDay = ts2;
jbsch.FrequencyInterval = 1;
System.DateTime d = default(System.DateTime);
d = new System.DateTime(2003, 1, 1);
jbsch.ActiveStartDate = d;
//Create the job schedule on the instance of SQL Agent.
jbsch.Create();
}
