-

i having 2 tables.

partylist

create table partylist (   sno serial not null,  party_title text,  party_venue text,  party_date date,  party_list character varying,  amount_list text );

list

create table list(       sno integer,   participant_name text,   amount_paid integer   );

this full sql fiddle.

i want call function can insert values both tables. , output should . partylist table

 | sno | party_title |    party_venue |                    party_date |                                                         party_list |             |amount_list     ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------     |   1 |       games | indoor stadium | august, 10 2013 00:00:00+0000 |            ronald;sania;sachin;pointing;samueal;gibbs;gayle;smith; |  100;200;100;100;200;100;100;100; |     |   2 |       dance |          stage | august, 15 2013 00:00:00+0000 | micheal jakson; britney ; daddy yankee; ar rehaman; jestin bebber; |200;100;100;200;100; |

list table

| sno | participant_name | amount_list --------------------------------------- |   1 |           ronald |      100 |   1 |            sania |      200 |   1 |           sachin |      100 |   1 |         pointing |      100 |   1 |          samueal |      200 |   1 |            gibbs |      100 |   1 |            gayle |      100 |   1 |            smith |      100 |   2 |   micheal jakson |      200 |   2 |          britney |      100 |   2 |     daddy yankee |      100 |   2 |       ar rehaman |      200 |   2 |    jestin bebber |      100

when call function these values in example below.

insert_function('games','indoor stadium','08-10-2013','ronald;sania;sachin;pointing;samueal;gibbs;gayle;smith;','100;200;100;100;200;100;100;100;'), ('dance','stage','08-15-2013','micheal jakson; britney ; daddy yankee; ar rehaman; jestin bebber;','200;100;100;200;100;');

is there way split list items (integer) , call insert query of list table in loop ?

you can use regexp_split_to_table function:

create or replace function insert_party(     _title text, _venue text, _date date,     _list text, _amount_list text ) returns void $body$ begin     cte (        insert partylist(party_title, party_venue, party_date, party_list, amount_list)        values (_title, _venue, _date, _list, _amount_list)        returning sno     ), cte2 (        select            sno,            regexp_split_to_table(_list, ';') participant_name,            regexp_split_to_table(_amount_list, ';') amount_paid        cte     )     insert list (sno, participant_name, amount_paid)     select sno, participant_name, amount_paid::int     cte2     participant_name not null , participant_name <> ''; end; $body$ language 'plpgsql' volatile cost 100;

sql fiddle demo

actually, it's possible write function sql , not plpgsql, see, it's 1 statement.

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...
