sql server 2008 - SQL splitting a word in separate characters -

-

i need change application , first thing need change field in database table. in table have 1 6 single characters, i.e. 'abcdef' need change '[a][b][c][d][e][f]'

[edit] meant stay in same field. before field = 'abcdef' , after field = '[a][b][c][d][e][f]'.

what way this?

rg. eric

you can split string separate characters using following function:

create function ftstringcharacters (     @str varchar(100) ) returns table return     v1(n) (         select 1 union select 1 union select 1 union select 1 union select 1         union         select 1 union select 1 union select 1 union select 1 union select 1     ),     v2(n) (select 1 v1 a, v1 b),     v3(n) (select top (isnull(datalength(@str), 0)) row_number() on (order @@spid) v2)     select n, substring(@str, n, 1) c     v3 go

and apply as:

update t set t.fieldname = p.fieldmodified tablename t     cross apply (         select (select quotename(s.c)         ftstringcharacters(t.fieldname) s         order s.n         xml path(''), type).value('text()[1]', 'varchar(20)')     ) p(fieldmodified)

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...
