How to delete all the rows in a table using Eloquent?

The reason MyModel::all()->delete() doesn't work is because all() actually fires off the query and returns a collection of Eloquent objects.

You can make use of the truncate method, this works for Laravel 4 and 5:

MyModel::truncate();

That drops all rows from the table without logging individual row deletions.

Laravel 5.2+ solution.

Model::getQuery()->delete();

Just grab underlying builder with table name and do whatever. Couldn't be any tidier than that.

Laravel 5.6 solution

\App\Model::query()->delete();

You can use Model::truncate() if you disable foreign_key_checks (I assume you use MySQL).

DB::statement("SET foreign_key_checks=0");
Model::truncate();
DB::statement("SET foreign_key_checks=1");

I've seen both methods been used in seed files.

// Uncomment the below to wipe the table clean before populating

DB::table('table_name')->truncate();

//or

DB::table('table_name')->delete();

Even though you can not use the first one if you want to set foreign keys.

Cannot truncate a table referenced in a foreign key constraint

So it might be a good idea to use the second one.

There is an indirect way:

myModel:where('anyColumnName', 'like', '%%')->delete();

Example:

User:where('id', 'like' '%%')->delete();

I wanted to add another option for those getting to this thread via Google. I needed to accomplish this, but wanted to retain my auto-increment value which truncate() resets. I also didn't want to use DB:: anything because I wanted to operate directly off of the model object. So, I went with this:

Model::whereNotNull('id')->delete();

Obviously the column will have to actually exists, but in a standard, out-of-the-box Eloquent model, the id column exists and is never null. I don't know if this is the best choice, but it works for my purposes.

simple solution:

 Mymodel::query()->delete();

I wasn't able to use Model::truncate() as it would error:

SQLSTATE[42000]: Syntax error or access violation: 1701 Cannot truncate a table referenced in a foreign key constraint

And unfortunately Model::delete() doesn't work (at least in Laravel 5.0):

Non-static method Illuminate\Database\Eloquent\Model::delete() should not be called statically, assuming $this from incompatible context

But this does work:

(new Model)->newQuery()->delete()

That will soft-delete all rows, if you have soft-delete set up. To fully delete all rows including soft-deleted ones you can change to this:

(new Model)->newQueryWithoutScopes()->forceDelete()

You can try this one-liner which preserves soft-deletes also:

Model::whereRaw('1=1')->delete();

The best way for accomplishing this operation in Laravel 3 seems to be the use of the Fluent interface to truncate the table as shown below

DB::query("TRUNCATE TABLE mytable");

The problem with truncate is that it implies an immediate commit, so if use it inside a transaction the risk is that you find the table empty. The best solution is to use delete

MyModel::query()->delete();

In a similar vein to Travis vignon's answer, I required data from the eloquent model, and if conditions were correct, I needed to either delete or update the model. I wound up getting the minimum and maximum I'd field returned by my query (in case another field was added to the table that would meet my selection criteria) along with the original selection criteria to update the fields via one raw SQL query (as opposed to one eloquent query per object in the collection).

I know the use of raw SQL violates laravels beautiful code philosophy, but itd be hard to stomach possibly hundreds of queries in place of one.

In my case laravel 4.2 delete all rows ,but not truncate table

DB::table('your_table')->delete();

Solution who works with Lumen 5.5 with foreign keys constraints :

$categories = MusicCategory::all();
foreach($categories as $category)
{
$category->delete();

}
return response()->json(['error' => false]);
