【问题描述】：

如何在 Laravel 中编写以下原始查询

 $result=  DB::select('SELECT a.awb_number,a.full_awb_number,a.service_type, b.city AS From_city, c.country_code AS From_country, b.city AS To_city, c.country_code AS To_country, datediff( max(s.created_at), min(s.created_at)) as Aging FROM customer_shippments a LEFT JOIN addresses b ON a.from_address = b.id LEFT JOIN addresses c ON a.to_address = c.id LEFT JOIN statuses s ON s.awb_number = a.awb_number WHERE a.full_awb_number IN ("LA172827289EE", "LA172828854EE", "LA172829894EE") GROUP BY s.awb_number');
   return $result;

在执行上述查询时，我收到以下错误

SQLSTATE[42000]: Syntax error or access violation: 1055 'track.a.awb_number' isn't in GROUP BY (SQL: SELECT a.awb_number,a.full_awb_number,a.service_type, b.city AS From_city, c.country_code AS From_country, b.city AS To_city, c.country_code AS To_country, datediff( max(s.created_at), min(s.created_at)) as Aging FROM customer_shippments a LEFT JOIN addresses b ON a.from_address = b.id LEFT JOIN addresses c ON a.to_address = c.id LEFT JOIN statuses s ON s.awb_number = a.awb_number WHERE a.full_awb_number IN ("LA172827289EE", "LA172828854EE", "LA172829894EE") GROUP BY s.awb_number)

【问题讨论】：

你使用什么 DBMS？

mysql 数据库管理

【参考方案1】：

如果您有参数，可能会发生此错误 'strict' => true 在 config/database.php 中为您提供数据库连接。

您可以将此参数设置为 false，或更改您的查询，以便“select”中的所有字段都表示在“group by”中

【讨论】：

我已将参数 'strict'=> 设置为 false 但不起作用

@user5370838，请检查一下，也许您的数据库设置有ONLY_FULL_GROUP_BY 参数。要检查这一点，请运行 SELECT @@sql_mode; 查询并检查结果是否为 ONLY_FULL_GROUP_BY。如果有，您可以使用 SET GLOBAL sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY','')); 查询禁用此功能

@ Andrew Markhai 我用这个原始查询试过了，先生....tq 对你的支持非常有用 public static function getstatusData() return DB::connection('mysql')->select ('SELECT a.awb_number,a.full_awb_number,a.service_type, b.city AS From_city, b.city AS To_city, datediff( max(s.created_at), min(s.created_at)) 作为 Aging FROM customer_shippments a LEFT JOIN地址 b ON a.from_address = b.id WHERE a.full_awb_number IN ("LA172827289EE", "LA172828854EE", "LA172829894EE") GROUP BY s.awb_number');

【参考方案2】：

使用 DB::raw()，但在使用 DB::raw 之前尝试先清理数据以防止 SQL 注入

$result = DB::raw('select blablabla')->get();
return $result;
