sp_开始_作业等待作业完成[重复]

这 article 描述启动sql代理作业并等待的SP。

-- output from stored procedure xp_sqlagent_enum_jobs is captured in the following table
    declare @xp_results TABLE ( job_id                UNIQUEIDENTIFIER NOT NULL,
                                last_run_date         INT              NOT NULL,
                                last_run_time         INT              NOT NULL,

    -- start the job
    declare @r as int
    exec @r = msdb..sp_start_job @job

    -- quit if unable to start
    if @r<>0
        RAISERROR (N'Could not start job: %s.', 16, 2, @job)

    -- start with an initial delay to allow the job to appear in the job list (maybe I am missing something ?)
    WAITFOR DELAY '0:0:01';
    set @seccount = 1

    -- check job run state
    insert into @xp_results
    execute master.dbo.xp_sqlagent_enum_jobs 1, @job_owner, @job_id

    set @running= (SELECT top 1 running from @xp_results)

    while @running<>0
    begin
        WAITFOR DELAY '0:0:01';
        set @seccount = @seccount + 1

        delete from @xp_results

        insert into @xp_results
        execute master.dbo.xp_sqlagent_enum_jobs 1, @job_owner, @job_id

        set @running= (SELECT top 1 running from @xp_results)
    end

    -- result: not ok (=1) if still running

    if @running <> 0 begin
        -- still running
        return 0
    end
    else begin

        -- did it finish ok ?
        set @run_status = 0

        select @run_status=run_status
        from msdb.dbo.sysjobhistory
        where job_id=@job_id
          and cast(run_date as bigint) * 1000000 + run_time >= @start_job

        if @run_status=1
            return 1  --finished ok
        else  --error
            RAISERROR (N'job %s did not finish successfully.', 16, 2, @job)

    end

    END TRY

XP_SQLAGENT_ENUM_JOBS 可以使用,但未记录。 它通常用于检测长时间运行的作业。

当然也有 sp_help_jobs 或者只是监视工作历史记录表

 sp_help_job   @job_name   @execution_status = 0

SELECT TOP 1 1 AS FinishedRunning
FROM msdb..sysjobactivity aj
JOIN msdb..sysjobs sj on sj.job_id = aj.job_id
WHERE aj.stop_execution_date IS NOT NULL
AND aj.start_execution_date IS NOT NULL
AND sj.name = 'YourJobNameHere'
AND NOT EXISTS
(
    SELECT TOP 1 1
    FROM msdb..sysjobactivity New
    WHERE New.job_id = aj.job_id
    AND new.start_execution_date > aj.start_execution_date
)

事实上,我最近不得不这么做,这就是我考虑实施它的方式。我正在通过sp_add_job和sp_add_jobstep创建一个临时作业,并将@delete_级别设置为3(运行后始终删除)。

我并不是100%赞同这种方法,从存储过程的标题可以看出这一点。然而,它确实有效:

CREATE PROCEDURE spWorkaround_checkJobExists

@job_id UNIQUEIDENTIFIER   
, @thisIteration tinyint  
, @maxRecurse tinyint

AS

IF (@thisIteration <= @maxRecurse)
BEGIN
    IF EXISTS(
    select * FROM msdb.dbo.sysjobs where job_id = @job_id
    ) 
    BEGIN
        WAITFOR DELAY '00:00:01'
        DECLARE @nextIteration int
        SET @nextIteration = @thisIteration + 1
        EXEC dbo.spWorkaround_checkJobExists  @job_id, @nextIteration, @maxRecurse
    END
END

当然,你会想输入一些代码,以确保有一个最大的次数,这将递归,但你明白的想法。您还可以传入一个参数来控制递归发生的频率。就我而言,十秒钟后,结果毫无意义。

我在这里所做的工作可以通过更改选择条件来检查作业的执行状态,例如,通过sp_help_job传递@job_name或@job_id和@execution_status=0来修改,以便在执行后不会立即删除作业。
