so I have 2 CSV files (user and bank_account) that I want to insert into my database, these 2 files have the user_number field that connected these two files, some user data doesn't have bank_account data. I want to insert to the database only user that has bank_account. I've tried to compare a user with a bank account for each loop, so if there are 1000 bank_accounts one user will loop 1000 times if the bank account not exists and it takes really long time. I want to know if there's a way to do it faster thanks. I'm using Laravel
