Question

我想运行以下查询

INSERT INTO static_pages (`page_name`, `title`, `page_display_order`) SELECT 'test','test', MAX(page_display_order)+1 FROM static_pages;

如何使用laravel eloquent执行此查询？这可能吗？

更新

谢谢@Joseph Silber

我使用了这个，就像

一样

$staticpage->page_display_order = DB::raw("($subquery)");
$staticpage->save();

这有助于获得最后插入的ID。

将DB::raw()与子查询一起使用：

$subquery = DB::table((new StaticPage)->getTable() . ' as page_alias')
              ->selectRaw('page_display_order + 1 as pdo')
              ->orderBy('page_display_order', 'desc')
              ->take(1)->toSql();

StaticPage::create([
    'page_name' => 'test',
    'title' => 'test',
    'page_display_order' => DB::raw("($subquery)"),
]);

Laravel 4：在laravel中插入max + 1
