prepared-statement

I'm writing a semi-simple database wrapper class and want to have a fetching method which would operate automagically : it should prepare each different statement only the first time around and just bind and execute the query on successive calls. I guess the main question is: How does re-preparing the same MySql statement work, will PDO magically recognize the statement (so I don't have to) and cease the operation? If not , I'm planning to achieve do this by generating a unique key for each different query and keep the prepared statements in a private array in the database object - under its

I can't seem to find where documented to successfully prepare a statement that uses the POINT data type. This previous question ( How to use POINT mysql type with mysqli - php ) shows something marked as correct, but it doesn't work. I even tried using their simple query in their example: $stmt = $this->conn->prepare("INSERT INTO days(day,POINT(lat,lon)) VALUES(?,?,?)"); $stmt->bind_param("sdd", $day, $lat, $lon); This just simply returns and error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '(lat,lon))

I have mysql stored procedure and i want to call to that and procedure name in a variable i used prepared statements but it gave me an error , im not a expert in mysql. here is the prepared statement > PREPARE stmt1 FROM 'CALL ? (?,?,?)'; SET @q = 'sys_search'; SET @a ='All_Employees'; SET @b = 1; SET @c = 1; EXECUTE stmt1 USING @q,@a,@b,@c; can any one give me the solution? @Rahul , @Tim Biegeleisen Thank you for your responses. I used this statements to work done. SET @q = 'sys_search'; SET @q2 = CONCAT('CALL ',@q,'(?,?,?)'); PREPARE stmt1 FROM @q2; SET @a = 'All_Employees'; SET @b = 1; SET

I just started using Php Data Objects and one thing I'm not sure about is do I have to validate that some variable is an integer before using it in the query. For example, like this: $id = (int)$_POST['id']; // is this required $query = $pdo->prepare("SELECT * FROM `articles` WHERE `id` = ?"); $query->bindValue(1, $id); $query->execute(); No it's not required for two reasons: You're letting PDO know that you are going to query the database for a column ID. PDO isn't going to parse anything in $_POST['id'] . The second value of bindValue is automatically casted to a string (or of any type you

Help. I am getting 0 num_rows but if i execute the query in the console i am getting results. I m kinda new to prepared stmts. Here is my code Database connection class: class DbConnection { const HOST = "localhost"; const USR = "root"; const PWD = ""; const DB = "club_db"; } Login class: class UsrLogin extends DbConnection { private $conn; /*db connector*/ /*login vars*/ private $usr; private $pwd; /*ctrl var*/ public $AccessGranted = false; function __construct($username,$password){ /*initialize db connection*/ $this->conn = new mysqli(DbConnection::HOST,DbConnection::USR,DbConnection::PWD

This is how I presently fetch from the DB: if ($stmt = $mysqli->prepare ( "SELECT fname,lname from $table_name where cno >=? LIMIT 50" )) { $stmt->bind_param ( "i", $cno); $stmt->execute (); $stmt->bind_result ($fname,$lname); $arrayUsers = array(); while ($stmt->fetch()) { if (isset ($fname)) { $arrayUsers[] = array( "fname" => $fname, "lname" => $lname); } } $stmt->close (); } $mysqli->close (); and it works great. But if I change my select to SELECT * from ... my bindings fail. Does that mean if I have a large number of fields, I will still have to specify each and every field or is there a
