Okay if we have a table named Student and we want to select all the students in that table
The Query : Select * from Student
and if we have a table Teacher which is in relation with the table Student and we want to select the student name and his teacher name
The query : select student_name , teacher_name
From [Student] Join Teacher
On [Student].teacher_Id = teacher_Id

Then you need two Join operations in the same query to read from the 3 tables
You need to read and understand the JOIN notion
