Symfony entity datetime field update fails

Question

I am working on a Symfony project. In one of the entities I have to update a Datetime field, but each time I create a new Datetime object and set it to my entity property and call the flush() function I get an error saying:

An exception occurred while executing UPDATE tablename SET update = ? WHERE id = ? with params ["2015-04-23 15:31:50", 2]

FYI: Everything works fine if I don't update the Datetime field.

//Here is what I set to the Datetime field:
$eo->setUpdate();

//The function in the Entity
public function setUpdate() {
    $this->update = new \DateTime('now', new \DateTimeZone('UTC'));

    return $this;
}

//And the field declaration
/**
 * @var \DateTime
 *
 * @ORM\Column(name="update", type="datetime", nullable=false)
 */
private $update;

EDIT :

I forgot this:

SQLSTATE[42000]: Syntax error or access violation: 1064 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 "update = "2015-04-23 15:53:29" WHERE id = 2" at line 1

Any ideas on why I get that exception ?

Answer 1

So basically the error was due to the fact that I was using an reserved word update as a column name in my database -_-

Kudos to @Nemutaisama for helping me figure this out. As he didn't post an answer to this question I am doing it, hope it helps others.
