SQL 查询作业活动监视器的状态

Question

我正在尝试编写查询以查找 SQL 代理作业的当前状态。此字段位于作业活动监视器的“状态”列下。请看下面的截图：

我正在使用在这个站点上找到的查询（查询也在下面），这很好，但它返回的状态是已经运行的作业的状态。

有谁知道查询当前状态与工作结束状态的方法？在上面的例子中，我想返回“Executing 1(Run Query)”。“运行查询”是作业第 1 步的名称。

保存状态信息的表实际上是一个名为 的扩展存储过程xp_sqlagent_enum_jobs。它是通过访问sp_help_job其记录在这里。如果您sp_help_job在没有参数的情况下调用，它将包括列current_execution_status，current_execution_step这就是您所追求的。

如果你在里面做一些挖掘sp_help_job，你可以看到它xp_sqlagent_enum_jobs是用以下参数调用的：

IF ((@@microsoftversion / 0x01000000) >= 8) -- SQL Server 8.0 or greater
    INSERT INTO @xp_results
    EXECUTE master.dbo.xp_sqlagent_enum_jobs @can_see_all_running_jobs, @job_owner, @job_id
ELSE
    INSERT INTO @xp_results
    EXECUTE master.dbo.xp_sqlagent_enum_jobs @can_see_all_running_jobs, @job_owner

您可以更进一步，复制临时表的结构并自己调用它，以便您可以挑选结果：

declare @job_name sysname = 'fill in your jobname here';
declare @job_id uniqueidentifier = (select top 1 job_id from msdb..sysjobs where name = @job_name);
declare @job_owner sysname = (SELECT SUSER_SNAME());
declare @xp_results TABLE (
    job_id                UNIQUEIDENTIFIER NOT NULL,
    last_run_date         INT              NOT NULL,
    last_run_time         INT              NOT NULL,
    next_run_date         INT              NOT NULL,
    next_run_time         INT              NOT NULL,
    next_run_schedule_id  INT              NOT NULL,
    requested_to_run      INT              NOT NULL, -- BOOL
    request_source        INT              NOT NULL,
    request_source_id     sysname          COLLATE database_default NULL,
    running               INT              NOT NULL, -- BOOL
    current_step          INT              NOT NULL,
    current_retry_attempt INT              NOT NULL,
    job_state             INT              NOT NULL);

INSERT INTO @xp_results
    EXECUTE master.dbo.xp_sqlagent_enum_jobs 1, @job_owner, @job_id

SELECT sj.name,
    case xpr.job_state when 1 then 'Executing: ' + cast(sjs.step_id as nvarchar(2)) + ' (' + sjs.step_name + ')'
        when 2  then 'Waiting for thread'
        when 3 then 'Between retries'
        when 4  then 'Idle'
        when 5  then 'Suspended'
        when 7  then 'Performing completion actions'
    end as [status]
FROM @xp_results                          xpr
inner join msdb..sysjobs sj on xpr.job_id = sj.job_id
LEFT OUTER JOIN msdb.dbo.sysjobsteps sjs ON ((xpr.job_id = sjs.job_id) AND (xpr.current_step = sjs.step_id)),
    msdb.dbo.sysjobs_view                sjv
WHERE (sjv.job_id = xpr.job_id)

请注意，如果您只是将 @job_name 保留为 null，它将为所有作业返回。
