linked server to excel permissions -

-

ok, give up, have no clue , desperately need help. loath excel storing data but... can do?

what want do:

allow user data .xls file via stored procedure , linked server (using microsoft.ace.oledb.12.0)

tthe problem:

user gets error:

ole db provider "microsoft.ace.oledb.12.0" linked server "ls" returned message   "the microsoft access database engine cannot open or write file ''.   opened exclusively user,     or need permission view , write data.". msg 7303, level 16, state 1, line 1 cannot initialize data source object of ole db provider   "microsoft.ace.oledb.12.0" linked server "ls".

administrator runs select * ls...[data$] , gets full rowset

what did:

i gave user permissions temp in sql service account directory.
user has full control on file linked server connected.

what sure of:

file not opened user.

resolved

there custom *.mdw file provider (i found somewhere in registry, hkey_local_machine/software/microsoft) turned out user didn't have permissions open file.

thx answers :)

(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...
