javascript - SQL - Check For Duplicate Values -

-

(this project written in js)

so, have table called paid_offers, , 2 columns called offer_id , entity_id i'm trying count of offer_id values associated single entity_id.

edit: example: entity_id has 35 offers available (so, there 35 rows unique offer_ids, same entity_id)

so, getting count no problem arraylist.length, need approach getting actual array. help!

edit: per request, more information! i'm going using output array.

so, project written using titanium (from appcelerator). don't need besides query. so, it'd what's inside quotes here, don't know.

var offerslist = db.execute("select entity_id paid_offers");

now, goal not list of id's instead list of offer_id values associated each unique entity_id value. think close to:

var offerslist = db.execute("select offer_id paid_offers entity_id = entity_id

except wouldn't work, that's train of thought while looking through this.

if you're trying count offers each entity, it's

select entity_id, count(offer_id) count   paid_offers group entity_id

this find entities @ least 1 offer.

c++ - Using OpenSSL in a multi-threaded application -

-
i have been writing soap client application in c++ on ubuntu using openssl https transport , pthreads threading. have number of threads - 1 central data acquisition thread periodically gets worker threads make soap requests via shared mutex protected queues. reading documentation openssl found is openssl thread-safe? in openssl faq describes mechanisms required ensure thread safety when using openssl. implemented , works fine. the reason question conceptual difficulty really. thinking implementing same functionality application has already, instead of using threads, create 2 seperate applications : 1 worker thread (of multiple copies running) , main data acquisition thread. use tcp sockets communicate between 2 rather mutex protected queues. may bad idea not important - confusing me would have implement same functions required ensure openssl thread safety in second approach or not? my guess not have , treated independent (indeed surely must many applications use openssl) re...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
