php - Elegant Efficient way of inserting into a lot of tables MySQL -

-

i making survey , database has 19 tables , 100 columns. of them inserted required fields. looking elegant , efficient way of inserting many tables , columns. far have come create multidimensional array contains first key table name , second key column name field. below:

    $tablearray =  array(          'ownertable' => array(             'firstnamerow' => $firstname,             'lastnamerow' => $lastname         ),         'dealertable' => array(             'dealernamerow' => $dealername,             'dealercityrow' => $dealercity             )         );  foreach($tablearray $row => $key) {     foreach($tablearray[$row] $row1) {         $sql = "(insert $tablearray[$key] ($tablearray[$row]) values ($row1)";      }    }

i didn't test code thinking along lines work. think 1 problem see separate insert each column instead of 1 insert each table. can work on writing code load values array @ once solve problem before start getting carried away want make sure not making big mistake , waste time if there better way it. 

$tablearray =  array(          'ownertable' => array(             'firstnamerow' => $firstname,             'lastnamerow' => $lastname         ),         'dealertable' => array(             'dealernamerow' => $dealername,             'dealercityrow' => $dealercity             )         );  //it's bulj query execution in single statment; $i=1; $sql=""; foreach($tablearray $row => $key) {     foreach($tablearray[$row] $row1) {         //here can update value per row execution         if($i<=25)         {          $sql = $sql  + "(insert $tablearray[$key] ($tablearray[$row]) values ($row1);";          }         else         {             //execute sql statement here;             $i=0;             $sql="";         }     }    }

-
i'm trying subclass qstyleditemdelegate remove focus rectangle in qcombobox . even though i'm calling base implementation of paint function , nothing else, result different. looks if parts of style-sheet influence bounding box of item taken consideration. class pstyleditemdelegate(qstyleditemdelegate): def __init__(self, *args, **kwds): super(pstyleditemdelegate, self).__init__(*args, **kwds) def paint(self, *args, **kwargs): qstyleditemdelegate.paint(*args, **kwargs) what have paint unmodified qstyleditemdelegate ? as suggested tried replacing pyside pyqt4 , works, appears bug. update pyside 1.1.2 1.2.1 result same. unfortunately switch breaks other parts of code, if there no other suggestions i'm going accept answer. edit bug tracked here
