php - PDO multiple queries -

-

as of php version 5.3 pdo_mysql driver has been repleaced in favour of pdo_mysqlnd. introduced support multiple queries.

though, can't figure out how both result sets if more 1 select query has been passed. both queries have been executed, can't second 1 dumped.

$db->query("select 1; select 2;")->fetchall(pdo::fetch_assoc);

returns:

array(1) {   [0]=>   array(1) {     [1]=>     string(1) "1"   } }

it turns out need use pdostatement::nextrowset.

$stmt   = $db->query("select 1; select 2;"); $stmt->nextrowset(); var_dump( $stmt->fetchall(pdo::fetch_assoc) );

this return result second query.

it bit odd implementation. easier if multi-query statement return both results sets under 1 array. however, advantage implementation allows fetch every query using different fetch styles.

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...
