Symfony2 Syntax Error or Access Violation

Question

I cannot create my entity through the form because I have this error:

CRITICAL - PHP Exception Doctrine \ DBAL \ DBALException is not displayed: "exception occurred while executing" INSERT INTO Task (name, miscellaneous, url, attachment, time_estimated, start_at, finished_at, default, deadline, task_priority_id, task_id, project_id, task_category_id, user_id) VALUES (?,?,?,?,?,?,?,?,?,?,?,?,?,?)

default - mysql reserved word, you have to fix it:

/**
 * @ORM\Column(name="`default`", type="boolean", nullable=true)
 */
private $default;
