.net - SQL subquery return more that 1 value -

-

hi trying execute query row between number , trying rows between 10-20. using subquery can use row_number() function

the query fails error:

sql subquery return more 1 value

so need figure way out because need more 1 resulset out of query

procedure dbo.search      (     @search_text varchar(max),      @search_category varchar(max),     @page int,     @count int output     )        set nocount on      declare @lower_limit int = (@page-1)*10;      declare @upper_limit int = (@page * 10) + 1;     -- set @count =0      if @search_category='deal'      begin         set @count = (select count(*) dealdata dealinfo  '%' + @search_text + '%' or dealname '%' + @search_text + '%' or dealdescription  '%' + @search_text + '%' group dealid);         select x.dealid , x.row                  ( select dealid,row_number() over(order dealid) row dealdata dealinfo  '%' + @search_text + '%' or dealname '%' + @search_text + '%' or dealdescription  '%' + @search_text + '%'  group dealid)x            x.row < @upper_limit , x.row > @lower_limit      end

this full procedure , when try call following code exception @ _command.executereader(); subquery returned more 1 value. not permitted when subquery follows =, !=, <, <= , >, >= or when subquery used expression.

 _query = "search";                 _command = new sqlcommand(_query, _connection);                 _command.commandtype = commandtype.storedprocedure;                 _command.parameters.addwithvalue("@search_text", search_text);                 _command.parameters.addwithvalue("@search_category", search_category);                 _command.parameters.addwithvalue("@page", page);                 var returnparameter = _command.parameters.add("@count", sqldbtype.int);                 returnparameter.direction = parameterdirection.output;                 _reader = _command.executereader();                 while (_reader.read())                 {                     search_result index = new search_result();                     index.category_id = this._categoryidfromname(search_category);                     index.post_id = _reader.getvalue(0).tostring();                     _searchlist.add(index);                 }

the problem part of sp:

set @count = (  select count(*) dealdata                  dealinfo  '%' + @search_text + '%'                  or dealname '%' + @search_text + '%'                  or dealdescription  '%' + @search_text + '%'                  group dealid)

specifically, group dealid part. if have multiple dealid on table, going multiple rows result. obviously, can't assign on scalar variable. either @count need declared table variable (which change logic of rest of sp), or rid of group dealid, , verify gives desired results.

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...
