MySQL query fails on integrity constraint violation - mysql

Question

This query keeps failing with
Integrity constraint violation: 1048 Column 'login_name' cannot be null
My insert statement is...
$insertUserQuery = 'INSERT INTO `users` (
`login_name`,
`password`,
`first_name`,
`last_name`,
`company_name`,
`company_address`,
`country`,
`email`,
`phone_number`,
`agency_type`,
`sold_before`,
`authorised`,
`current_module`
)
VALUES (
:login_name, :login_password, :first_name, :last_name, :company_name, :company_address, :country, :email, :phone_number, :agency_type, :sold_before, 0, 0);';
$bindings = array(':login_name' => $loginName,
':login_password' => sha1($password . Config::PASSWORD_SALT),
':first_name' => $firstName,
':last_name' => $lastName,
':company_name' => $companyName,
':company_address' => $companyAddress,
':country' => $country,
':email' => $emailAddress,
':phone_number' => $phone,
':agency_type' => null,
':sold_before' => null
);
print_r($bindings);
Db::query($insertUserQuery, $bindings);
My database class can be found at another question. The print_r() tells me that the array definitely has a value.
May it have something to do with me using the word 'password' which is also a MySQL function?
Does PDO support prepared statements with INSERT in the same fashion as it does with SELECT?
Do I need to quote around the values, example ':login_name'?

Answer 1

PDO::query doesn't support prepared statement syntax does it? Give PDO::prepare and PDOStatement::execute a read. You probably want something like:
$insertUserQuery = 'INSERT INTO `users` (`login_name`, ...) ' .
'VALUES (:login_name, ...);';
$bindings = array(':login_name' => $loginName, ...);
$stmt = Db::prepare($insertUserQuery);
$stmt->execute($bindings);
You can also call $stmt->bindValue() instead of building an array of bindings. I think that explicitly binding each value is a little nicer since you can verify the types right there.
EDIT: sorry jcinacio, I didn't see that your comment was almost identical until after I posted.
