Question

I have on table assets and I want to update each code column as 'ASSET000'+ primary id of table like below

Asset0001 for id 1
Asset0002 for id 2
Asset0003 for id 3

In mysql query will be

UPDATE assets SET code = concat('ASSET000', id)

How can I write in Laravel

DB::table('assets')->update('code',????)

Using DB::raw() you can do it like this :

DB::table('assets')->update(['code' => DB::raw( CONCAT('ASSET000', id) )])
