php - Mysql insert and select query together convert to mysqli -


i have mysql query works great when try convert mysqli can not work: working sql query

<?php  require_once( 'opendb.php' );  $id = '105';     // start date     $date = '2015-11-10';     // end date     $end_date = '2015-11-15';      while (strtotime($date) <= strtotime($end_date)) {      $sql= "insert test (id,date,hours) select  id, '".$date."' date, case dayname('".$date."')     when 'sunday' sun     when 'monday' mon     when 'tuesday' tue     when 'wednesday' wed     when 'thursday' thu     when 'friday' fri     when 'saturday' sat else 0 end hours emp id = '".$id."'"; mysql_query($sql);     $date = date ("y-m-d", strtotime("+1 day", strtotime($date)));     }?>

not sure how use mysqli prepare statement when there select , insert in same query.

mysqli not working not sure how work

  <?php      $mysqli = new mysqli('localhost', 'xx', 'xx', 'xxx');      $id = '105';         // start date         $date = '2015-11-10';         // end date         $end_date = '2015-11-15';      $stmt = $mysqli->prepare('insert `test` (`id`, `date`,`hours`) values (?, ?, ?)');             while (strtotime($date) <= strtotime($end_date)) {            $sql= "select  id,     '".$date."' date,     case dayname('".$date."')         when 'sunday' sun         when 'monday' mon         when 'tuesday' tue         when 'wednesday' wed         when 'thursday' thu         when 'friday' fri         when 'saturday' sat     else 0 end '".$hours."'     emp id = 105 ";     $mysqli->query($sql);;           $stmt->bind_param('sss', $id , $date, $hours);             $stmt->execute();         $date = date ("y-m-d", strtotime("+1 day", strtotime($date)));         }     ?>

i understand how use prepare in insert statement not when insert , select statement together

the select statement taking each day column hours work on day table 1 eg id mon = 8 tue = 6 wed = 4 thu= 0 fri = 6 sat = 7 sun = 0 , insert them test table

it looks using select in sql date formatting. date formatting in php, instead. make mysqli insert plain vanilla insert.

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
