How to show (or log) all SQL queries executed by Laravel

Laravel: How to show (or log) all SQL queries executed by Laravel

There are a few ways to show the SQL queries that are generated and executed by Laravel

toSql() - You can replace ->get() (or ->paginate()) with ->toSql() to return a string of the SQL query that was generated

  1. $posts = Posts::where("type",$type)->get();
  2. // or as SQL statement
  3. $postsSql =  Posts::where("type",$type)->toSql();

But maybe you want to see all of the queries that Laravel executes for each request?

Query Logging - you can enable the query log, then somewhere else loop through each logged query:

  1. // put this somewhere...
  2. DB::connection()->enableQueryLog();
  3. // run some queries
  4. Posts::where("title","test")->get();
  5. User::find(1);
  6.  
  7. // then loop through this:
  8. $queries = DB::getQueryLog();

Or add a event listener for each query - Put this in your AppServiceProvider (or another file, such as your routes file or even in a controller)

  1. Event::listen('illuminate.query', function($query)
  2. {
  3.     dump($query);
  4. });

Just remember to take these bits of code out before pushing the changes to production!
