Question

尝试获取执行作业的会话ID

;with JobDetails as
(
select Job_Id = left(intr1,charindex(':',intr1)-1),
       Step = substring(intr1,charindex(':',intr1)+1,charindex(')',intr1)-charindex(':',intr1)-1),
       SessionId = spid
    from master.dbo.sysprocesses x 
    cross apply (select replace(x.program_name,'SQLAgent - TSQL JobStep (Job ','')) cs (intr1)
    where spid > 50 and x.program_name like 'SQLAgent - TSQL JobStep (Job %'
)
select * 
    from msdb.dbo.sysjobs j 
    inner join JobDetails jd on j.job_id = jd.Job_Id

但它会引发以下错误

消息8169，级别16，状态2，行47转换时转换失败从字符串到uniqueidentifier。

我尝试将job_id转换为varbinary，但不会产生结果

;with JobDetails as
(
select Job_Id = left(intr1,charindex(':',intr1)-1),
       Step = substring(intr1,charindex(':',intr1)+1,charindex(')',intr1)-charindex(':',intr1)-1),
       SessionId = spid
    from master.dbo.sysprocesses x 
    cross apply (select replace(x.program_name,'SQLAgent - TSQL JobStep (Job ','')) cs (intr1)
    where spid > 50 and x.program_name like 'SQLAgent - TSQL JobStep (Job %'
)
select * 
    from msdb.dbo.sysjobs j 
    inner join JobDetails jd on cast(j.job_id as varbinary) = jd.Job_Id

但是当我复制粘贴来自job_id的{{1}}

时

有效。知道如何修复此查询
