php - Combine multiple column values in to single value in SQL select statement -

-

i have autocomplete field user can enter lastname firstname middlename in same order.

using lastname firstname middlename (as term) have show autocomplete dropdown.

on database have 3 columns firstname lastname , middlename. have compare 3 column values (asc_lastname, asc_firstname, asc_middlename) of same row user input (term).

here sql query. please correct mistake.

$rs = mysql_query( "select asc_lastname, asc_firstname, asc_middlename issio_asc_workers inner join issio_workers_asc_sc_list  on  issio_asc_workers.lname_fname_dob=issio_workers_asc_sc_list.lname_fname_dob issio_workers_asc_sc_list.center_id='$cid'  , issio_workers_asc_sc_list.center_user_type = '31' , issio_workers_asc_sc_list.center_status <> 'deleted' ,  (issio_asc_workers.asc_lastname+' '+issio_asc_workers.asc_firstname+' '+issio_asc_workers.asc_middlename)  '". mysql_real_escape_string($term) ."%'  order issio_asc_workers.lname_fname_dob asc limit 0,10");

is possible compare 3 column values @ time using sql query like

 select *   table   (column1+''+column2+''column3) 'this good'

sorry poor sentences.

try query: 

select * your_table concat(column1, ' ', column2, ' ', column3) '%this good%'

documentation concat

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...
