问题 I have updated my original post based on what I learned from your comments below. It is a much simpler process than I originally thought. require '../database.php'; $pdo = Database::connect(); $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $sql = "SELECT * FROM Orders WHERE id = 430"; $q = $pdo->prepare($sql); $q->execute(array($id)); $data = $q->fetch(PDO::FETCH_ASSOC); echo 'Order Num: ' . $data['id'] . '<br>'; $sql = "SELECT * FROM Order_items JOIN Parts ON Parts.id = Order

问题 I'm trying to insert into a database for the first time using PDO but I keep getting the error Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY093]: Invalid parameter number: parameter was not defined' on line 25 Google tells me there is a mis match somewhere with the values I'm inserting but from what I can tell they add up $db = new PDO("mysql:host=$servername;dbname=$dbname",$username,$password); $db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $stmt =

I'm trying to replace the first instance of a NULl or ' ' value in a column with another value. But only the first instance and nothing else. So far I've put this together: UPDATE table_name SET column = CONCAT(REPLACE(LEFT(column , INSTR(column , '')), '', 'new_value'), SUBSTRING(column , INSTR(column , '') +1)

问题 I have a PDO statement which is supposed to look for data with pipes around it, I have multiple id's stored in a single column. I know this isn't great but it seems the logical way to store the data. Column content example |1|3|4|5|14|76| So I want to find every line in the database with 3 in it. I use a php form to post or get 3 $getthis = $_GET['getthis']; $sql = "SELECT * FROM table WHERE types LIKE '?' ORDER BY name"; $q = $conn->prepare($sql); $q->execute('%|$getthis|%'); while ($data =
