A database assignment can be maddening when a query runs successfully but returns the wrong information. There is no obvious error message, just a result that does not match the task. The impulse to “pay someone to take your online class” may come after another evening of trying changes without a plan. Begin with the question the query is meant to answer. Check what each table represents, which records should be included, and how the relationships affect the result. Test a smaller part of the query before combining everything again. A tutor can help you understand the logic and examine your approach without completing the graded task for you. Keep track of what each change is testing, especially when joins or filters are involved. A result that looks plausible is not enough on its own. Knowing why the correct rows appear gives you a more dependable foundation for the next database problem.
