What have you done till now, is there any issue for writing queries to retrieve the desired result?

When answering a question please:

Read the question carefully.
Understand that English isn't everyone's first language so be lenient of bad spelling and grammar.
If a question is poorly phrased then either ask for clarification, ignore it, or edit the question and fix the problem. Insults are not welcome.
Don't tell someone to read the manual. Chances are they have and don't get it. Provide an answer or move on to the next question.

We are not helping you if we do your homework, you should do it yourself as it is not that difficult. Take reference from here: SQL tutorial[^]
CP helps people to learn. We neither do their assignments/homeworks/projects nor supply source code.

If you encounter any difficulties with your coding, always consult Google first, everything else fails, then visit CP and ask questions related to specific issues.
