# Keys
One of De Monne's database engineers is having issues rebuilding the production database. He wants to know the name of one of the foreign keys on the `loans` database table. Submit one foreign key name as the flag: `flag{foreign-key-name}` (can be ANY foreign key).
Use the MySQL database dump from **Body Count**.
# InfoEZ-PZ, just look for the constraints on the schema.
```sqlCONSTRAINT `fk_loans_cust_id` FOREIGN KEY (`cust_id`) REFERENCES `customers` (`cust_id`) ON DELETE CASCADE,CONSTRAINT `fk_loans_employee_id` FOREIGN KEY (`employee_id`) REFERENCES `employees` (`employee_id`) ON DELETE CASCADE,CONSTRAINT `fk_loans_loan_type_id` FOREIGN KEY (`loan_type_id`) REFERENCES `loan_types` (`loan_type_id`) ON DELETE CASCAD```
## Flag
`flag{fk_loans_cust_id}`
