• 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

    /****** Object:  Job [syspolicy_purge_history]    Script Date: 04/29/2009 07:41:53 ******/
    BEGIN TRANSACTION
    DECLARE @ReturnCode INT
    SELECT @ReturnCode = 0
    /****** Object:  JobCategory [[Uncategorized (Local)]]]    Script Date: 04/29/2009 07:41:53 ******/
    IF NOT EXISTS (SELECT name FROM msdb.dbo.syscategories WHERE name=N'[Uncategorized (Local)]' AND category_class=1)
    BEGIN
    EXEC @ReturnCode = msdb.dbo.sp_add_category @class=N'JOB', @type=N'LOCAL', @name=N'[Uncategorized (Local)]'
    IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback

    END

    DECLARE @jobId BINARY(16)
    EXEC @ReturnCode =  msdb.dbo.sp_add_job @job_name=N'syspolicy_purge_history',
            @enabled=1,
            @notify_level_eventlog=0,
            @notify_level_email=0,

    IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback
    /****** Object:  Step [Verify that automation is enabled.]    Script Date: 04/29/2009 07:41:54 ******/

            END',
            @database_name=N'master',
            @flags=0
    IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback
    /****** Object:  Step [Purge history.]    Script Date: 04/29/2009 07:41:54 ******/

    IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback
    /****** Object:  Step [Erase Phantom System Health Records.]    Script Date: 04/29/2009 07:41:54 ******/

    EXEC @ReturnCode = msdb.dbo.sp_add_jobserver @job_id = @jobId, @server_name = N'(local)'
    IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback
    COMMIT TRANSACTION
    GOTO EndSave
    QuitWithRollback:
        IF (@@TRANCOUNT > 0) ROLLBACK TRANSACTION
    EndSave:

    GO

     

    2. 通过SMO的方式

    这里有一个完整的介绍

    http://msdn.microsoft.com/zh-cn/library/ms162162.aspx

    //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(); 
    }
