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

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 - gt newQuery  - gt 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 - gt newQueryWithoutScopes  - gt forceDelete

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  - gt 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

The reason MyModel  all  - gt 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

I ve seen both methods been used in seed files      Uncomment the below to wipe the table clean before populating  DB  table  table name  - gt truncate       or  DB  table  table name  - gt 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
