雄辩 |添加自定义值以选择

Question

我有多个表，它们都保存着不同的交易数据，这里是一个例子：

$q1 = DB::connection('mysql_live')->table('transactions_vk')->where('user_id', $userid)->where('amount', '!=', '0')->where('payed', 'Yes')
->select('type', 'id', 'package', 'payed', 'amount', 'date_modified as date_added', 'payed as chargeid')->get(); 

$q2 = DB::connection('mysql_live')->table('transactions_stripe')->where('user_id', $userid)->where('amount', '!=', '0')->where('payed', 'Yes')
->select('type', 'id', 'package', 'payed', 'amount', 'date_added', 'charge_id as chargeid')->get();

$total1 = $q1->merge($q2);

我将它们全部查询并将它们合并为一个结果。当我查询它们时，我知道它们是哪种支付类型，在我的示例中，q1 都是 VK 交易，q2 都是条带交易。

有没有办法在此处添加此信息？

类似于payment_type: VK 用于第一季度和payment_type: Stripe 用于第二季度？

因此结果数组将包含每个项目的此信息，项目将如下所示：

amount: 8999
chargeid: "pi_chargeid"
date_added: "2021-09-10 10:47:29"
id: 70
package: 31
payed: "Yes"
type: "credits"
payment_type: "VK"


amount: 2495
chargeid: "123456789"
date_added: "2016-09-19 17:15:43"
id: 70405
package: 11
payed: "No"
payment_type: "Stripe"

Answer 1

您可以做一些小技巧来在选择中添加一列，就像在纯 SQL 中一样：

$q1 = DB::connection('mysql_live')->table('transactions_vk')->where('user_id', $userid)->where('amount', '!=', '0')->where('payed', 'Yes')
->select('type', 'id', 'package', 'payed', 'amount', 'date_modified as date_added', 'payed as chargeid', DB::raw("'VK' as 'payment_type'"))->get(); 

$q2 = DB::connection('mysql_live')->table('transactions_stripe')->where('user_id', $userid)->where('amount', '!=', '0')->where('payed', 'Yes')
->select('type', 'id', 'package', 'payed', 'amount', 'date_added', 'charge_id as chargeid',DB::raw("'Stripe' as 'payment_type'"))->get();

$total1 = $q1->merge($q2);

更新：您的查询似乎与联合兼容，因此您可以通过以下方式为自己节省查询：

$q1 = DB::connection('mysql_live')->table('transactions_vk')->where('user_id', $userid)->where('amount', '!=', '0')->where('payed', 'Yes')
->select('type', 'id', 'package', 'payed', 'amount', 'date_modified as date_added', 'payed as chargeid', DB::raw("'VK' as 'payment_type'")); 

$q2 = DB::connection('mysql_live')->table('transactions_stripe')->where('user_id', $userid)->where('amount', '!=', '0')->where('payed', 'Yes')
->select('type', 'id', 'package', 'payed', 'amount', 'date_added', 'charge_id as chargeid',DB::raw("'Stripe' as 'payment_type'"));

$total1 = $q1->union($q2)->get();

Answer 2

在您的情况下，您可以编写这样的代码。

$q1 = DB::connection('mysql_live')->table('transactions_vk')->where('user_id', $userid)->where('amount', '!=', '0')->where('payed', 'Yes')
          ->select(DB::raw('"VK" AS payment_type, type, id, package, payed, amount, date_modified as date_added, payed as chargeid'))->get();
            
$q2 = DB::connection('mysql_live')->table('transactions_stripe')->where('user_id', $userid)->where('amount', '!=', '0')->where('payed', 'Yes')
           ->select(DB::raw('"Stripe" AS payment_type, type, id, package, payed, amount, date_added, charge_id as chargeid'))->get();
            
$total1 = $q1->merge($q2);
