sql server - how to know status of currently running jobs -

-

i need know if given job running on ms sql 2008 server. not invoke same job again may lead concurrency issues.

it looks can use msdb.dbo.sysjobactivity, checking record non-null start_execution_date , null stop_execution_date, meaning job started, has not yet completed.

this give running jobs:

select sj.name    , sja.* msdb.dbo.sysjobactivity sja inner join msdb.dbo.sysjobs sj on sja.job_id = sj.job_id sja.start_execution_date not null    , sja.stop_execution_date null

(i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
