$con->Insert('tab_teste',$data);
$data = Array('id'=>2,'name' => 'Second Record', 'col3' => 'test ');
$con->Insert('tab_teste',$data);
$data = Array('id'=>3,'name' => 'Third Record', 'col3' => 'test ');
$con->Insert('tab_teste',$data);
$con->Commit();

DELETE

$where = Array('id'=>1);
$con->Delete('tab_teste', $where);

$where = Array('id'=>2);
$con->Update('tab_teste',$data, $where);

$where = Array('id' => Array('BETWEEN'=>Array(2,3)));
$res = $con->Select('tab_teste',$where);
$tab = $res->fetch_all(MYSQLI_ASSOC);

WHERE

$where = 'id = 1'; 
// Result: id = 1

$where = Array('id' => 1); 
// Result: id = 1

$where = Array('id' => 1,'OR','col3' => 'test'); 
// Result: id = 1 OR col3 = 'test'

$where - Array('col3' => array('LIKE' => 'recor'))
// Result: col3 LIKE '%recor%'

$where = Array('id' => Array(1,'>>>',10, Array(3,6,8))); 
// Result: id IN (1,2,4,5,7,9,10)

$where = Array('id' => Array('BETWEEN' => Array(1,10)));
// Result:  id BETWEEN 1 AND 10

$where = Array('id' => Array('NOT' => Array(1,2,3,12,45)));
// Result: id NOT IN (1,2,3,12,45)

$where = Array('id' => Array('NOT' => Array(1,'>>>',10, Array(3,6,8)))); 
// Result: id NOT IN (1,2,4,5,7,9,10)


$where = Array(
  'id' => array('NOT' => array(1,'>>>',6,array(3,5))),
  'OR',
  'col3' => array('LIKE' => 'recor')
);
// Result: id NOT IN (1, 2, 4, 6) OR col3 LIKE '%recor%'
