在 Codeigniter 框架中更新（不執行）之前打印查詢

Question

我想在CODEIGNITER中的數據庫中更新之前打印查詢。

    $data['name'] = $name;
    $data['email'] = $email;
    $data['mobileNo'] = $mobileNo;
    $data['areaID'] = $areaID;
    $data['address'] = $address;
    $this->db->update('db_SaleDetail', $data);

Answer 1

我從來沒有使用過 Codeigniter，但我認為事務和回滾的東西會起作用：

$this->db->transStart(true); // start transaction, so we can rollback after
$data['name'] = $name;
$data['email'] = $email;
$data['mobileNo'] = $mobileNo;
$data['areaID'] = $areaID;
$data['address'] = $address;
$this->db->update('db_SaleDetail', $data);
var_dump( $this->db->last_query() ); // display the query
$this->db->transRollback(); // cancel update
