Insert a row into the employee table. If the department does not exist. Insert it into the departments table.Software engineering is about taking a complex problem, reducing it into smaller simpler problems, and then solving each of these simpler problems in turn. The end-result is a solution for the complex problem.
So do the following. Write 3 procedures:
- a procedure that takes employee data as input and inserts this into the employees table
- a procedure that takes department data as input and inserts this into the departments table
- a procedure (or function) that checks whether a specific department exists in the departments table
This is easy to do.
Once done, then you simply use these 3 building blocks in a new procedure that
a) checks if the department exists
b) inserts the department if it does not
c) inserts the employee
Keep in mind that a software engineering problem cannot be more simpler than this. You need to understand how to do this (simplifying the problem) and how the design and write the code for it. Real world problems are magnitudes more complex - and if you want to make software engineering a career, you should not be struggling to deal with the most elementary of problems.
