最后一个创建表的语句有问题：

<code class="sql">CREATE TABLE `imooc_album` (
    `id` int(10) auto_increment key,
    `pId` not null
);</code>

问题在于，没有指定pId的数据类型，改成下面这样就没问题了：

<code class="sql">DROP TABLE IF EXISTS `imooc_album`;
CREATE TABLE `imooc_album` (
    `id` int(10) auto_increment key,
    `pId` int(10) not null
);</code>
