Question

我有一个表Uuids，它与dealers, masterdealers, admins and customers表有一个变形关系。我需要从uuids表中获取所有上述用户类型表中的电子邮件地址及其uuids。我使用工会来获取经销商，经销商，管理员和客户表的所有电子邮件，但我也想以某种方式加载他们的uuids。

我想要的输出是这样的：

{
    email: 1@example.com
    uuid: 1
}, {
    email: 2@example.com
    uuid: 5
}, {
    email: 3@example.com
    uuid: 11
}

我试过了：

DB::select("SELECT email FROM customers
    UNION SELECT email FROM dealers
    UNION SELECT email FROM masterdealers
    UNION SELECT email FROM admins");

它给了我这4张桌子的所有电子邮件。

您需要加入变形表才能获得不同模型的uuids

<NavLink to={'/dashboard/profile/'  + (tab.url) + '/' + userId} activeClassName="selectedTab">
   <div>{tab.name}</div>
</NavLink>

另外，要在laravel中运行原始查询，您可能需要SELECT u.uuid,c.email FROM customers c JOIN Uuids u ON c.id = u.some_mapped_col AND u.some_morph_col = 'Model Name' UNION SELECT u.uuid,d.email FROM dealers d JOIN Uuids u ON d.id = u.some_mapped_col AND u.some_morph_col = 'Model Name' UNION SELECT u.uuid, m.email FROM masterdealers m JOIN Uuids u ON m.id = u.some_mapped_col AND u.some_morph_col = 'Model Name' UNION SELECT u.uuid, a.email FROM admins a JOIN Uuids u ON a.id = u.some_mapped_col AND u.some_morph_col = 'Model Name'
