Sorry, this is not a question at all. Tell you what? What would it mean possibly, "tell use table relation"? It does not require expert's advice, it's just about learning and doing your job. If you really need an expert's advice, ask appropriate questions, provide all the relevant detail.

Since May 15, when you asked your first question, you had enough time to figure out which question posts can work and which cannot. At least, take a look at the successful questions of others (those answered with formally accepted answers).

This is not a subject for Quick Questions & Answers. To know more, learn more. You never told us what exactly you want to know.

i need to know what it will do if i make a relation between two tables for examples between the patient name and the Reservation tables

Do you know keys and foreign keys? These are the basics of relational model and SQL. You need to start learning from the very beginning, such questions cannot help you.

Then you need to learn it, instead of calling yourself a noob, or anything like that. All right, you are a noob today, but are you going to stay a noob tomorrow?

Please see all my today's comments to your posts. With such questions, you go nowhere. Nevertheless, let me point you in some direction. You are asking about the very basics of relational model and databases. These articles should give you an idea on what you need to learn and provide some introduction:
https://en.wikipedia.org/wiki/Relational_database[^],
https://en.wikipedia.org/wiki/Relational_model[^],
https://en.wikipedia.org/wiki/Unique_key[^],
https://en.wikipedia.org/wiki/Foreign_key[^],
https://en.wikipedia.org/wiki/Database_schema[^],
https://en.wikipedia.org/wiki/Database_normalization[^] (more advanced, but essential),
https://en.wikipedia.org/wiki/Category:Data_modeling[^].

But the major problem is not all these topics. You need to develop the skills of learning thing. Asking questions is just a part of it. You demonstrate too much of helpless weakness. It can be learned of course, but it's hard to teach. Anyway, this Quick Questions & Answers forum is not a suitable place for getting instructions on that. You can learn how to learn things only by learning something intensively (as opposed to "extensively"), by learning practice, and by using your brain.

Remember the Eastern proverb:
Saying "halva-halva" won't make your mouth sweet.
