java - Custom Error from mysql to jdbc -

-

i want write stored procedure in mysql validates data before insertion table. use jdbc send custom message "zipcode not valid" java can displayed on screen. such thing possible?

at first want underline @duffymo absolutely right.

...but if still want write such procedure snippet might help:

delimiter ;; create procedure insert_checked_zip(zipdata int) begin     if (zipdata > 0)         insert mytable (zipcode) values (zipdata);     elseif         select 'zip invalid';     end if; end ;; delimiter ;

note: checks if passed zip bigger 0

please think of doing these checks on gui level - less expensive , faster (to list 2 advantages).

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...
