这是我的Model.Leave.php

    <?php

    namespace Application\Model;

    use Doctrine\ORM\Mapping as ORM;
    use Doctrine\Common\Collections\ArrayCollection;

    /**
     * @ORM\Table(name="leave")
     * @ORM\Entity
     */
    class Leave extends Entity
    {
        /**
         * @ORM\Column(type="string", length=100)
         * @var string
         */
        protected $employee;


        public function getEmployee()
        {
            return $this->employee;
        }

        public function setEmployee($emp)
        {
            $this->employee = $emp;
        }

        /**
         * @ORM\Column(type="string", length=100)
         * @var string
         */
        protected $type;


        public function getType()
        {
            return $this->type;
        }

        public function setType($type)
        {
            $this->type = $type;
        }

        /**
         * @ORM\Column(type="string", length=100)
         * @var string
         */
        protected $days;


        public function getDays()
        {
            return $this->days;
        }

        public function setDays($days)
        {
            $this->days = $days;
        }

    }

请参阅http://doctrine-orm.readthedocs.org/en/latest/reference/basic-mapping.html#quoting-reserved-words

您需要引用保留字，例如

/**
 * @ORM\Table(name="`leave`")
 * @ORM\Entity
 */

使用doctrine添加新字段时显示PDO异常错误
