sql server - T-Sql condition check -

-

i have table there column called allocated_to. if there value in column, means status of row assigned otherwise unassigned.

from search box sending 1 assigned , 0 unassigned. have 2 more similar checks pending , closed on column named signoff (type: int).

now have total of 9 search criteria

1. pending 2.closed 3. unassigned 4. assigned 5. pending + unassigned 6. pending + assigned 7. closed + unassigned 8. closed + assigned 9. records irrespective of statuses.

so how add condition query. change in sp , sp , running. cant make huge change in query, making dynamic or whatsoever.

i can give sample here , how query looks like:

if some_condition  begin    select x,y,zfrom t1 join t2 on t1.a=t2.b    isnull(signoff,0)=@paramforpendingandclosed  end

now add above 9 check in where, help??

please note:

i can't take heavy alterations, need make in each , every if-else condition. query has 4-5 if else depending upon header condition, please not suggest me go dynamic procedures. other welcome.

you add couple of optional parameters allow specify whether results should include pending/closed or assigned/unassigned results. way maintain single, flexible way of retrieving results.

take @ this answer overview of using optional parameters in sql.

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...
