Hi SO, I am in the process of designing a web app (really it's a hobby, I'm trying to teach myself design, and what better way is there than doing it :). Anyways, I was thinking about how I would deal with my database. I am comfortable with PDO and I was thinking of leveraging PDO in my abstraction class. I am thinking of making a si...
Hi all, We can use prepare method to get the query prepared for multiple time use in PDO. But i want to know that can we see all the queries executed at the DB. For e.g see below: <?php // Cosidering DB connection already set here. With $db. // using named placeholder $db->prepare("select * from user where id=:id"); ...
I am doing a query which fetches two fields. I need each of those fields into a different array. Will this rerun the query for each call or just re iterate over the result set? $a= Laststatment->fetchAll(PDO::FETCH_COLUMN,0); $b= Laststatment->fetchAll(PDO::FETCH_COLUMN,1); ...
I set up a site on my local system using PDO and a MySQL Database. I used PDO because when the site goes on the live server I have to user SQL Server and I was hoping PDO would take care of all my query conflicts. Now that I'm up on the live server I get an error whenever the application uses the "LIMIT" function. I realize this is a My...
I want to populate class with constructor using FETCH_INTO of PDO: class user { private $db; private $name; function __construct($id) { $this->db = ...; $q = $this->db->prepare("SELECT name FROM users WHERE id = ?"); $q->setFetchMode(PDO::FETCH_INTO, $this); $q->execute(array($id)); ...
I have the following insert function. Is it safe from a sql injection. If it isn't then how do I make it safe. public function insert($postValues, $table){ $dbh = $this->connect(); try { $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $fields = implode(array_keys($postValues), ','); $val...
how would i get a random rowcount using PDO? i'm still learning how to use PDO so this is what i tried, but it didn't work because it doesn't randomize the quotes: $sql = "SELECT COUNT(*) AS rows FROM thquotes;"; try { $query = $this->_db->prepare($sql); $query->execute(); ...
I have a SQLite database that I am using for a website. The problem is that when I try to INSERT INTO it, I get a PDOException SQLSTATE[HY000]: General error: 8 attempt to write a readonly database I SSH'd into the server and checked permissions, and the database has the permissions -rw-rw-r-- I'm not that familiar with *nix permis...
Are PDO transcations intended just for UPDATE, INSERT and DELETE or can you achieve performance gains if you use a transaction for mulitple SELECT queries? ...
I'm trying to use binding in PDO to select some entries from a Microsoft SQL database. The code I'm using looks like it's similar to what I've found in the documentation. However, when I run it, I get the warning below: Warning: PDOStatement::execute() [pdostatement.execute]: SQLSTATE[42000]: Syntax error or access violation: 1087 [M...
like in /* Exercise PDOStatement::fetch styles */ print("PDO::FETCH_ASSOC: "); print("Return next row as an array indexed by column name\n"); $result = $sth->fetch(PDO::FETCH_ASSOC); print_r($result); print("\n"); print("PDO::FETCH_BOTH: "); print("Return next row as an array indexed by both column name and number\n"); $result = $sth->...
I can't find any information on these constants but the sparse bit the documentation gives. What can they be used for, and do I to use them? ...
In PDO, a connection can be made persistent using the PDO::ATTR_PERSISTENT attribute. According to the php manual, these connections are not closed at the end of the script, but are cached and re-used when another script requests a connection using the same credential. The persistent connection cache allows someone to avoid the overhead ...
I think the question itself is pretty self-explanatory. The code is given below - <?php $PDO = NULL; $pdo_dsn = 'mysql:host=localhost;dbname=pdo_test'; $pdo_persistence = array( PDO::ATTR_PERSISTENT => true ); $db_user = 'root'; $db_pass = ''; $db_query = "INSERT INTO person(name, address) VA...
I have extended PDOStatement and modified the fetch() method to typecast values of the types timestamp and arrays, in PostgreSQL, to DateTime and native array. This works as intended but I can't override the behaviour when using the statement in a foreach. I have solved this by returning rows into an object implementing ArrayAccess, Ite...
