null - SQL input needed to get correct output -

- 

select a.subscriberkey, a.eventdate,b.createddate _click join _listsubscribers b on a.subscriberkey = b.subscriberkey b.listid = '10630' , b.createddate > (select dateadd(day,-180,getdate())) , a.eventdate null group a.subscriberkey,b.createddate, a.eventdate

at moment, nothing being returned. want return subscribers subscriberkey(which email), eventdate(the date click took place), , date added(createddate) when have not clicked on anything. can point me in right direction? everyone!

i don't see purpose of group in case. aren't doing aggregation.

i believe give result looking for.

select subscriberkey,        null eventdate,        createddate   _listsubscribers ls  listid='10630'    , createddate > dateadd( day, -180, getdate())    , not exists( select 1 _click c c.subscriberkey = b.subscriberkey )

the following query using outer join should give same results, , more similar original query.

select ls.subscriberkey,        c.eventdate,        ls.createddate   _listsubscribers ls   left outer join _click c     on c.subscriberkey = ls.subscriberkey  listid='10630'    , createddate > dateadd( day, -180, getdate())    , c.eventdate null

c# - Copy ObservableCollection to another ObservableCollection -

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

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...
