update room set selected = 1 room_id = (select room_id room_rev rev_id = (select rev_id room_rev room_id = 'rom0001' , (start_date<='2015-03-20' , end_date>'2015-03-20'))) can me simplify query? i want select many room_id room_rev same rev_id room_id = 'rom0001', room_id use update selected room , room_rev 1 many relationship you can use join like: update r set r.selected = 1 room r inner join room_rev rr on r.room_id = rr.room_id rr.room_id = 'rom0001' , (rr.start_date<='2015-03-20' , rr.end_date>'2015-03-20')

i have following query select q.pol_id quot q ,fgn_clm_hist fch q.quot_id = fch.quot_id union select q.pol_id tdb2wccu.quot q q.nr_prr_ls_yr_cov not null for every row in result set, want create new row in table (call table1) , update pol_id in quot table (from above result set) generated primary key inserted row in table1. table1 has 2 columns. id , timestamp. i'm using db2 10.1. i've tried numerous things , have been unsuccessful quite while. thanks! simple solution: create new table result set of query, has identity column in it. then, after running query, update pol_id field newly generated id in result table. alteratively, can more manually using row_number() olap function, found convenient creating ids. convenient use stored procedure following: get maximum old id table1 , write variable old_max_id . after generating result set, write row-numbers table1 , maybe like insert table1 select row_number() on (partition <primary-key

the motivating use-case have in mind follows: in play framework controller, calling play's ws . produces potentially-failing future i want handle separate cases of ws request succeeding vs failing. in both cases, want produce play response (likely future[response] ) what think trying is: asynchronously, after future completes, unconditionally handle completion produce future[response] corresponding desired response i don't believe can use future.map because need customize handling of failure case , not pass on future 's failure. if have alternative suggestions how solve cleanly, please let me know. you're looking future.recover . val wsresponse: future[wsresponse] = ??? wsresponse map { response => // success case ok(response.json) } recover { // failure case, turn throwable response case t: throwable => internalservererror(t.getmessage) } recover takes partial function throwable => t . in case, t option[resp

i don't know in codding understand basic python. wanted challenge myself writing program solve next - considering store giving 3 options - x$ per day, y$ per month or z$ per year, combination best me assuming want t amount of time? now, far can understand, have here basic combinatoric question creating tree of combinations, , need of shortest-path algorithms (djikstra, bellman-ford..?) finding best option ("shortests","less expensive") please me find need approach problem. this instance of multiple item knapsack problem , time weight, , "value" cost. knapsack size amount of time want. in here want minimize value, equivalent maximizing negatives (assume day "costs -x, month -y, year -z). this can solved following recursive formula (assuming costs integers or can brought integers), , can implemented rather efficiently using dynamic programming . d(0,0) = 0 d(x,0) = infinity x>0 d(x,i) = infinity x < 0 d(x,i) = min{ d(x,

i have big file, teh lines text numbers etc. [man-(some numers)] lot of man-somenumbers repeat in few lines, want count unique mans -words. cant use unique file , because text before man words different in each line. how can count unique man-somenumbers words in file ? if understand want correctly, then grep -oe 'man-[0-9]+' filename | sort | uniq -c should trick. works follows: first grep -oe 'man-[0-9]+' filename isolates words file match man-[0-9]+ regular expression. list piped through sort sorted list uniq requires, , sorted list piped through uniq -c count how each unique man- word appears.

i have .so files , jar, when run error: unable identify apk variant arm-debug , device. i'm noob here must doing wrong, cant seem figure out. ideas? using android studio 1.1.0 , genymotion emulation. this build file looks like: apply plugin: 'com.android.application' android { compilesdkversion 22 buildtoolsversion "22.0.0" defaultconfig { applicationid "com.ctech.music.androidstreamer" minsdkversion 14 targetsdkversion 22 versioncode 1 versionname "1.0" } buildtypes { release { minifyenabled false proguardfiles getdefaultproguardfile('proguard-android.txt'), 'proguard-rules.pro' } } productflavors { x86 { ndk { abifilter "x86" } } arm { ndk { abifilters "armeabi-v7a", "armeabi" }

i have doubt regarding favicon , can add favicon directly in html file following code. <link rel="shortcut icon" type="image/x-icon" href="favicon.ico" /> i have tried above code, it's working fine. have seen there modules in npm server favicon images. if add through html , why have use modules serve. for case of serve-favicon module: why use module? user agents request favicon.ico , indiscriminately, may wish exclude these requests logs using middleware before logger middleware. this module caches icon in memory improve performance skipping disk access. this module provides etag based on contents of icon, rather file system properties. this module serve compatible content-type.

i'm new javafx , trying display large amount of text in textflow. displays fine, cannot figure out how delete text. so i'm trying delete text nodes textflow so textflow.getchildren().removeall(); but when , add textflow, shows after text displayed there. text there removed , show added text beginning of textflow. i guess have somehow rerender view of textflow, don't know how. how delete , add text anew? removeall(...) remove values pass parameters: in case there none, doesn't remove anything. use textflow.getchildren().clear();

first of all, i'm beginner in c. program simulates server client connects via telnet on port 8000 , give username , password , server validates them. username client, have problem validating it. need compare username list of credentials, doesn't seem work. here's code i've written far... #include <stdio.h> #include <sys/socket.h> #include <arpa/inet.h> #include <unistd.h> #include <string.h> int main() { char * credentialslist[7][2] = {{"alice","abcdef"}, {"bob","1234567"}, {"cindy","qwerty"}, {"david","abababab"}, {"eve", "cdefgh"}, {"frank","7654321"}, {"george", "12341234"}}; int serversocket=socket(af_inet, sock_stream, 0); int new_socket, i; char *message, client_message[10]; struct sockaddr_in server, client; server.sin_family = af_inet; server.sin_addr.s_addr

in ruby can created array filled types: [1, 'hello', :world] # [fixnum, string, symbol] => [1, "hello", :here] how implement similar array filled mixed types in go? how declare array? you can via empty interface - interface{} : arr := make([]interface{}, 0) arr = append(arr, "asdfs") arr = append(arr, 5) or in literal form: arr := []interface{}{"asdfs", 5} whenever want use value of array need use type assertion.

problem is, in case of e of type htmlelement this causes performance issue $(e) !== $(e) instead of reusing jquery object, jquery creates new object each time when call $(e) $(e).attr(.... $(e).css(... $(e).find(.... for each statement, new jquery object created , performance increases when do var $e = $(e); $e.attr(.... $e.css(... $e.find(.... so decided cache rewriting $ below. instead of changing huge code. var $old = window.$; var $ = function(o){ if(typeof htmlelement === "object" ? o instanceof htmlelement : o && typeof o === "object" && o !== null && o.nodetype === 1 && typeof o.nodename==="string"){ o.__$ = o.__$ || $old(o); return o.__$; } return $old(o); }; $.prototype = $old.prototype; after $(e) === $(e) returns true, , in context of page, if called multiple times, runs pretty fast. however, $.trim, $.isarray function gone,

so need write program generates random numbers 100 999, , tricky part digits in number can't same. for example: 222 , 212 , on not allowed. so far, have this: import random = int (random.randint(1,9)) <-- first digit b = int (random.randint(0,9)) <-- second digit c = int (random.randint(0,9)) <-- third digit if (a != b , != b , b != c): print a,b,c as can see, generate 3 digits separately. think it's easier check if there same digits in number. so, want loop generate numbers until requirements met (now either prints blank page or number). note generates once , have open program again. in c++ did ' while loop '. , here don't know how it. and 1 more question. how can code number(quantity) of random numbers want generate? more specific: want generate 4 random numbers. how should code it? p.s. thank answers , suggestions, keen on learning new techniques , codes. to loop until it's ok can use while in python: from ra

i'm new js, css , html feel excited explore more. my visualization , whole code here: https://gist.github.com/dariaalekseeva/a71475378a5d12ea40bc at moment when move mouse across object, many paths appear , not easy see details. i'd change setting in visualization hovering clicking. first hover , active paths change. pick 1 path, click on , path stays active. , still should able see appearing comments when hover along path. need "unclick" path (or click outside object) , keep hovering until find path click on. thank help. you need modify mousemove mousedown . changed display tip click event, not 'hover'. i created plunkr that, display tip clicking. http://plnkr.co/edit/rn76z5z8cxzpqkkm7pen (i modified mousemove mousedown @ 218 line.) you can use 'mouseout', 'mousedown', 'mousemove' implement these kinds of interaction.

first of must i'm total noob in c++ programing. have make funcion: void license(bool& exists, unsigned int longlicense, unsigned int license[]) it has read txt file contains 6 hex numbers separated "-", example: 462e3784-11f24312-13b57611-27a3197f-3b30158a-ab7ef8e0 and save numbers (in decimal) in "license" array. has return true or false in "exists". i've tried doing doesn't work. reads correctly first number. rest of them aren't same have in txt file. #include <iostream> #include <fstream> #include <string> #define n_int_license 6 using namespace std; bool existe; unsigned int licencia[n_int_license]; ifstream stream; stream.open("license.txt"); if (stream) { (int = 0; < n_int_license; i++) { stream >> hex >> licencia[i]; } i didn't find other topic me if there 1 i'm sorry posting that. please me. thank you. you should skip dash: f

i have project named "shortcut", here issue & steps cd shortcut vim .gitignore git init git add * git status i still see .exe files , .pdb files in staging. what's wrong git operation steps ??? here .gitignore file [dd]ebug/ [dd]ebugpublic/ [rr]elease/ [rr]eleases/ *.exe *.pdb *.dll i think you're confused, although it's hard tell where. consider following: $ mkdir shortcut $ cd shortcut $ touch foo $ echo foo > .gitignore $ git init initialized empty git repository in ~/shortcut/.git/ $ git add * following paths ignored 1 of .gitignore files: foo use -f if want add them. fatal: no files added
