How to Implement Pessimistic Locking in Laravel 5

You don't want anybody to do any action with a record in some situations, you're dealing with it. I can use DB lock to take possessiong of a particular record.

Laravel provides two ways of dealing with negative locking.  

sharedLock

Shared lock is given read access to a given record when more than one transaction is authorized.

DB::table('tbl_order')->where('amount', '>', 100)->sharedLock()->get();
