在运行时更改严格模式

Question

我只想对控制器内部的一个查询而不对整个laravel应用程序禁用MySQL严格模式，

我知道禁用MySQL严格模式的风险，所以我不想从config / database.php中为整个应用程序禁用它，

我在整个应用程序中只遇到一个查询，因此我想在我的控制器中禁用它，然后只运行一次查询！

请帮我解决给定情况。

Answer 1

在运行时更改严格模式

config()->set('database.connections.mysql.strict', false);
\DB::reconnect(); //important as the existing connection if any would be in strict mode
Model::select()->get(); // your query called in non strict mode

//now changing back the strict ON
config()->set('database.connections.mysql.strict', true);
\DB::reconnect();

Answer 2

在config / database.php中，执行以下操作：

'connections'=> [

    'mysql' => [

        // Behave like MySQL 5.6

        'strict' => false,

        // Behave like MySQL 5.7
        'strict' => true,
    ]

]

Answer 3

将它用于≤5.7的MySQL（摘自here）：

DB::statement("set session sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'");
// your query
DB::statement("set session sql_mode='ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'");

您可以做的一件事就是在运行时更改此值

public function doQueryWithoutStrictMode{
    config('database.connections.mysql.strict', false);
    DB::select('The query you want to make, and that should work!');

    And then, if you later want to do another query in strict mode withing the same 
    method you can enable it like this.

    config('database.connections.mysql.strict', true);

    DB::select('your other query with strict mode');

}

仅对一个查询禁用MySQL Strict Mode Laravel 5.6
