explicitly specify the column names to be populated in the table
Cause of foreign key issue
Tried loading data using the below command
$ mysql db_test1 -u root < load_dept_manager.dump
Reported Error:
ERROR 1452 (23000) at line 1: Cannot add or update a child row: a foreign key constraint fails (`db_test1`.`dept_manager`, CONSTRAINT `dept_manager_ibfk_1` FOREIGN KEY (`emp_no`) REFERENCES `employees` (`emp_no`) ON DELETE CASCADE)
When opened and viewed the dept_manager the column order were not matching and thus specifying column order explicitly in insert query fixes the problem.
