How to Get the Query Executed in Laravel 5? DB::getQueryLog() Returning Empty Array

How to Get the Query Executed in Laravel 5? DB::getQueryLog() Returning Empty Array. 📝

Have you ever found yourself scratching your head, wondering why Laravel's DB::getQueryLog() is returning an empty array when you're trying to view the log for a query? 🤔 Don't worry, you're not alone! In this blog post, we'll explore this common issue and provide some easy solutions to help you get the query executed in Laravel 5. Let's dive in! 💻

Understanding the Problem 👀

When you call DB::getQueryLog(), Laravel returns an array of all the executed queries during the current request. However, if you're seeing an empty array as a result, it means that Laravel hasn't logged any queries yet. 😬

Common Causes and Solutions 💡

1. No Query Logging Enabled: By default, Laravel does not enable query logging. So, if you haven't explicitly enabled query logging in your application, you won't see any queries in the log. To enable query logging, you can add the following line of code to your AppServiceProvider in the boot() method:

DB::connection()->enableQueryLog();

1. Query Execution Order: Another reason for an empty query log could be the order of execution. If you're calling DB::getQueryLog() before actually executing any queries using Eloquent or the Query Builder, the log will naturally be empty. Ensure that you've executed your queries before calling DB::getQueryLog().

2. Caching Queries: Laravel has built-in query caching mechanisms that can sometimes interfere with the DB::getQueryLog() function. If you're using query caching, it's possible that the cached version of the query is being served instead of executing the actual query. Make sure to disable query caching temporarily when you want to view the executed query log.

DB::connection()->disableQueryLog();

1. Multiple Database Connections: If your application is configured to use multiple database connections, make sure you're accessing the correct connection when checking the query log. DB::getQueryLog() fetches the executed queries for the default database connection. If you're using a different connection, you'll need to specify it explicitly when calling getQueryLog().

DB::connection('connection_name')->getQueryLog();

Example Usage 🔧

To better understand how to get the query executed using DB::getQueryLog(), let's consider an example. Suppose you have the following code:

$user = User::find(5);
print_r(DB::getQueryLog());

To ensure you can see the executed query log, make sure query logging is enabled in your application and that the execution order is correct. Then, executing the code snippet should give you the desired result:

Array
(
    [0] => Array
        (
            [query] => select * from `users` where `id` = ?
            [bindings] => Array
                (
                    [0] => 5
                )

            [time] => 0.42
        )
)

As you can see, the executed query log now contains the query, its bindings (if any), and the execution time.
