java - Spring JDBCTemplate Update issue -

-

in table definition, there column int data type. if value "0", want jdbctemplate update method update field "null" instead of "0" default.

this.jdbctemplate.update("update gcur_observation "                 + "set observerid = ?," + "observationdate = ?,"                 + "pointcuring = ?"                 + " locationid = ? , observationstatus = 0",                 new object[] { new integer(newobservation.getobserverid()),                         newobservation.getobservationdate(),                         new integer(newobservation.getlocationid()) });

the code snippet above runs when point curing not null. however, how can stored null in database table?

i hope getting null pointer exception.

try this

integer locid = null;  if(newobservation.getlocationid() != null) {  locid = new integer(newobservation.getlocationid());  if(locid == 0) {    locid = null;  } }

and pass locid here.

this.jdbctemplate.update("update gcur_observation "                 + "set observerid = ?," + "observationdate = ?,"                 + "pointcuring = ?"                 + " locationid = ? , observationstatus = 0",                 new object[] { new integer(newobservation.getobserverid()),                         newobservation.getobservationdate(),                         locid) });

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...
