mysql "IN" condition with subquery -

-

i need execute following:

select * mp_sizes  size_id in(select size_ids mp_size_categories  category_id = '3' , sub_category_id = '5');

when run below query return me 3 records.

select * mp_sizes size_id in(3,2,4);

also when run sub query showing me correct result.

select size_ids mp_size_categories  category_id = '3' , sub_category_id = '5';

the above query gives result 3, 2, 4.

but when use in sub query returns 1 record. return size details of first value (3) only.

how can results of 3 sizes (3, 2, 4)?

have tried using join? (which faster)

 select * mp_sizes, mp_size_categories  size_id = size_ids , category_id = '3'  , sub_category_id = '5';

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...
