Select last 5 rows in join query SQL Server 2008 -

-

i trying bring last 5 rows of order table based on orderdate column name firstname customer table.

the below query displays values order table instead of last 5 rows.

select      a.[firstname], b.[orderid], b.[orderdate], b.[totalamount], b.[orderstatusid]      [schema].[order] b  outer apply    (select top 5  *     [schema].[customer]       b.[customerid] = 1        , a.[customerid] = b.[customerid]     order       b.[orderdate] desc)

any mistake in logic of using top , desc ?

if want last 5 rows of order table, why apply top customer table?

select top 5 a.[firstname],b.[orderid],b.[orderdate],b.[totalamount],b.[orderstatusid]  [schema].[order] b  left join [schema].[customer] on a.[customerid]=b.[customerid]  b.[customerid]=1  order  b.[orderdate] desc

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (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...
