Get query log or print query log in laravel; In this tutorial, we are going to show you how to get query log or print query in laravel apps.
Laravel’s Eloquent ORM (Object-Relational Mapping) provides an intuitive and convenient way to interact with databases. Eloquent abstracts the underlying database operations, making it easy to write and execute queries. However, when developing a complex application, it can be challenging to monitor the queries that are being executed. In such cases, logging the queries can be useful to track the application’s performance and identify potential issues. In this article, we will discuss how to get the query log in Laravel Eloquent.
How to Get Query Log in Laravel
Using the following steps, you can get query log or print query log in laravel apps; as following:
- Step 1: Enable query logging
- Step 2: Retrieve the query log
- Step 3: Customize query logging
Step 1: Enable query logging
To log queries in Laravel, we need to enable query logging in the database configuration file. Open the config/database.php file and set the logging parameter to true, as follows:
'mysql' => [
//...
'logging' => true,
//...
],
By setting logging to true, Laravel will log all queries executed by the application.
Step 2: Retrieve the query log
Laravel’s Eloquent ORM provides a convenient way to retrieve the query log. After executing a query, we can retrieve the query log using the getQueryLog method on the DB facade:
use Illuminate\Support\Facades\DB;
$results = DB::table('users')->get();
$queryLog = DB::getQueryLog();
In this code, we first execute a query to retrieve all users from the database using the get method. After executing the query, we retrieve the query log using the getQueryLog method.
The getQueryLog method returns an array of all queries executed by the application, with each query represented as an associative array. The array contains the SQL query and an array of its bindings.
Step 3: Customize query logging
If you want to customize the query logging behavior, you can use the Laravel Query Logger package. The package provides a more comprehensive way to log queries and can be easily integrated into your Laravel application.
To use the package, first, install it using composer by running the following command:
composer require barryvdh/laravel-query-logger
After installing the package, you can configure it in the AppServiceProvider.php file as follows:
use Barryvdh\LaravelQueryLogger\QueryLoggerServiceProvider;
public function register()
{
if ($this->app->environment('local')) {
$this->app->register(QueryLoggerServiceProvider::class);
}
}
In this code, we check if the application environment is “local” and register the QueryLoggerServiceProvider if it is. This ensures that query logging is only enabled in the local environment.
Conclusion
Retrieving the query log in Laravel Eloquent is a simple process that provides valuable insights into the application’s behavior. By logging queries, we can gain valuable insights into the application’s performance and optimize it for better performance. Laravel’s Eloquent ORM provides a convenient way to retrieve the query log, and with the Laravel Query Logger package, we can customize the query logging behavior. By monitoring the query log, we can identify potential issues and optimize our Laravel application for better performance.
