P_ID exam No.
P_NAME exam name
P_TIME
T_ID instructor ID
So how do you differentiate the created tables from different tests?

What I want is to extract some question numbers from the question bank to create a new exam table,
------ Solution --------------------
Yes. The varchar type is sufficient. In this case, select * from THE where id in ('1, 2, 3 '); // Obtain the questions 1, 2, and 3.

PHP code

Question numbers are separated by commas. is that string type? How can we extract the data during extraction?
------ Solution --------------------
When saving, use the question number and store it in a good connection. Loop output is required for extraction.
