Uncaught exception 'PDOException' with message 'SQLSTATE[42S22]: Column not found: 1054

I tried to run the following code but it gets this error:


Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[42S22]: Column not found: 1054 Unknown column 'ani123' in 'where clause'' in D:\xampp\htdocs\New folder\FINAL PROJECT\QQUIZ\admin\teacher\t_action.php:44 Stack trace: #0 D:\xampp\htdocs\New folder\FINAL PROJECT\QQUIZ\admin\teacher\t_action.php(44): PDO->exec('DELETE FROM `qu...') #1 {main} thrown in D:\xampp\htdocs\New folder\FINAL PROJECT\QQUIZ\admin\teacher\t_action.php on line 44


Here is my code:

$dltQuizesSql = "DELETE FROM `quizes` WHERE `username`=".$_GET['user']; // line 44
$stmt1 = $conn->exec($dltQuizesSql);


And here is an image of my table:


username
exists in my table but I still get the error.

How can I solve it?

Answer Source

1) string should be enclosed by single quotes

 "DELETE FROM quizes WHERE username='".$_GET['user']."'"; 

2) Remove semicolon inside the brackets

( $stmt1 = $conn->exec($dltQuizesSql);)
