php – 在Laravel 4中通过迁移脚本创建MySQL视图

class CreateMyView extends Migration {

    public function up()
    {
        DB::statement( 'CREATE VIEW myview AS SELECT [your select statement here]' );
    }

    public function down()
    {
        DB::statement( 'DROP VIEW myview' );
    }

}

然后你可以创建一个模型来访问它：

class MyView extends Eloquent {

    protected $table = 'myview';

}

然后,要从应用中的其他位置访问该视图,您可以像查询任何其他模型一样查询该视图,例如

MyView::all();  // returns all rows from your view
MyView::where( 'price','>','100.00' )->get();  // gets rows from your view matching criteria

道具转到下面提供了有关如何执行此操作的信息：

警告

如果以后的迁移会修改视图下的表,请务必小心.原因是per the documentation：

The view definition is “frozen” at creation time,so changes to the underlying tables afterward do not affect the view definition. For example,if a view is defined as SELECT * on a table,new columns added to the table later do not become part of the view.

真的,我想你必须小心这样的东西才能进行任何迁移,所以也许这不是什么大问题.
