可能重复:
从存储过程执行 SQL Server 代理作业并返回作业结果

使用 sp_start_job 启动 sql 代理作业后,有没有办法确定它何时完成?

本文介绍了一个 SP 启动一个 sql 代理作业并等待。

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

当然,也有sp_help_jobs或只是监控作业历史表

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
)

实际上我最近不得不这样做,这就是我正在考虑实施它的方式。我正在通过 sp_add_job 和 sp_add_jobstep 创建一个临时作业,并将 @delete_level 设置为 3(总是在运行后删除)。

我不是 100% 相信这种方法的,正如您可能从存储过程的标题中看出的那样。但是,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,您需要输入一些代码来确保递归的最大次数,但您明白了。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。

我在这里所做的可以通过更改选择标准以检查作业的执行状态来修改不打算在执行后立即删除的作业,例如,使用 sp_help_job 传递 @job_name 或 @job_id 和 @execution_status = 0。
