php - Changing Multiple values in MySQL with a single Query -

-

i want change different column values of table in 1 query, possible?

i tried (just guess):

<?php $q="update tab set name='samit' id='1' && set name='anju' id='4'"; $run=mysql_query($q); if($run){ echo 'updated'; } else{ echo 'update failed'; } ?>

it's not working. can using loop, loop increase operation time.

you can use join

update tab t1 join tab t2     on t1.id = 1 , t2.id = 4    set t1.name = 'samit',        t2.name = 'anju'

here sqlfiddle demo

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...
