mysqli

问题 I've got a number of stored procedures made with the MySQL Workbench. They work just fine when use MySQL workbench to put them into my test DB. Now I am preparing the DB creation scripts for deployment, and this is the only one giving me trouble. When I use the command line / mysql shell, the script works perfectly well to. It's only when I use the PHP mysql(i) interface to execute the script - it fails. Without comment. I use the procedure creation scripts as MySQL workbench generates for me

问题 So I found this great function that converts mysql queries into a XML page, and it looks like exactly what I need. The only problem is that it uses mysql, but thats not supported anymore, and it turns out one of the functions used isn't in mysqli. Does anyone know of an alternative to mysql_field_name? Here's the function that I found function sqlToXml($queryResult, $rootElementName, $childElementName) { $xmlData = "<?xml version=\"1.0\" encoding=\"ISO-8859-1\" ?>\n"; $xmlData .= "<" .

问题 I am trying to output the variables that I get from the database in my query but nothing is being returned. Using MYSQLi prepared statements. Please see code below: $stmt = $con->prepare("SELECT first_name, last_name FROM transactions WHERE order_id = ?"); $stmt->bind_param('i', $order_id); $stmt->execute(); $stmt->store_result(); $stmt->bind_result($first_name, $last_name); $stmt->close(); // Output review live to page echo $first_name; I cannot see where I am going wrong? PS I am new to

问题 This is how I get one record with MySQLi: $result = $db->query("..."); $image = $result->fetch_object(); Now I need to get the comments and pass it to the view. I'm doing this right now but it doesn't seem right: $result = $db->query("..."); while ($row = $result->fetch_object()) $comments[] = $row; I'm wondering if there's a way to remove the loop? Something like have $image = $result->fetch_object(((s))), so my code would look like: $result = $db->query("..."); $comments = $result->fetch

问题 Hi I'm kinda new to this and I would like to ask someone here that are experts in codeigniter framework and PHP. How can I use mysqli drivers in php native query? For example. My code: Model class Home_model extends CI_Model{ public function getusers(){ $q = "SELECT * FROM `users`"; return $r = mysqli_query($q); } } Controller: class Home extends CI_Controller{ public function iterateuser(){ while($row = mysqli_fetch_object($this->Home_model->getusers())){ echo $row->username; } } My code

问题 Ive followed a bunch of different examples regarding using a SELECT in a prepared statement, but nothing is returned. EDIT I have changed my code a bit to look like this: $date1 = 2012-01-01; $date2 = 2012-01-31; $sql_con = new mysqli('db', 'username', 'password', 'database'); if($stmt = $sql_con->prepare("SELECT eventLogID FROM Country WHERE countryCode=? AND date BETWEEN ? AND ?")){ $stmt->bind_param("sss", $country_code, $date1,$date2); $stmt->execute(); $i=0; while ($stmt->fetch()){ $stmt

问题 Historically, I've always used mysql_real_escape_string() for all input derived from users that ends up touching the database. Now that I've completely converted over to MySQLi and I'm using prepared queries with bound parameters, have I effectively eliminated the possibility of SQL injection attacks? Am I correct in saying I no longer need mysql_real_escape_string()? This is my understanding and the basis of a project of mine: http://sourceforge.net/projects/mysqldoneright/files/Base

问题 Can someone please tell me why this doesnt work, when I tried to switch my old sql to sqli: $query = "SELECT * FROM `product_category`"; $result = mysql_query($query, $connect) or die("could not perform query: " . mysql_error()); $num_rows = mysql_num_rows($result); for ($i=0; $i < $num_rows; $i++) { $ID = mysql_result($result,$i,"ID"); $name = mysql_result($result,$i,"name"); $description = mysql_result($result,$i,"description"); to: $query = ("SELECT * FROM `product_category`"); $result =
