Get the Query Executed in Laravel 3/4

Question

How can I retrieve the raw executed SQL query in Laravel 3/4 using Laravel Query Builder or Eloquent ORM?

For example, something like this:

DB::table('users')->where_status(1)->get();

Or:

(posts (id, user_id, ...))

User::find(1)->posts->get();

Otherwise, at the very least how can I save all queries executed to laravel.log?

Answer 1

Laravel 5

Note that this is the procedural approach, which I use for quick debugging

    DB::enableQueryLog();

    // Run your queries
    // ...

    // Then to retrieve everything since you enabled the logging:
    $queries = DB::getQueryLog();
    foreach($queries as $i=>$query)
    {
        Log::debug("Query $i: " . json_encode($query));
    }

in your header, use:

     use DB;
     use Illuminate\Support\Facades\Log;

The output will look something like this (default log file is laravel.log):

[2015-09-25 12:33:29] testing.DEBUG: Query 0: {"query":"select * from 'users' where ('user_id' = ?)","bindings":["9"],"time":0.23}

***I know this question specified Laravel 3/4 but this page comes up when searching for a general answer. Newbies to Laravel may not know there is a difference between versions. Since I never see DD::enableQueryLog() mentioned in any of the answers I normally find, it may be specific to Laravel 5 - perhaps someone can comment on that.

Answer 2

in Laravel 4 you can actually use an Event Listener for database queries.

Event::listen('illuminate.query', function($sql, $bindings)
{
    foreach ($bindings as $val) {
        $sql = preg_replace('/\?/', "'{$val}'", $sql, 1);
    }

    Log::info($sql);
});

Place this snippet anywhere, e.g. in start/global.php. It'll write the queries to the info log (storage/log/laravel.log).

Or as alternative to laravel 3 profiler you can use:

Answer 4

Last query print

$queries = \DB::getQueryLog();
$last_query = end($queries);

// Add binding to query
foreach ($last_query['bindings'] as $val) {
        $last_query['query'] = preg_replace('/\?/', "'{$val}'", $last_query['query'], 1);
}
dd($last_query);

Answer 5

For Eloquent you can just do:

$result->getQuery()->toSql();

But you need to remove the "->get()" part from your query.

Answer 6

Using the query log doesnt give you the actual RAW query being executed, especially if there are bound values. This is the best approach to get the raw sql:

DB::table('tablename')->toSql();

or more involved:

$query = Article::whereIn('author_id', [1,2,3])->orderBy('published', 'desc')->toSql();
dd($query);
