SQL Inner join more than two tables

Question

I can currently query the join of two tables on the equality of a foreign/primary key in the following way.

 $result = mysql_query(\"SELECT * FROM `table1` 
         


        

Answer 1

Please find inner join for more than 2 table here

Here are 4 table name like

1. Orders
2. Customers
3. Student
4. Lecturer

So the SQL code would be:

select o.orderid, c.customername, l.lname, s.studadd, s.studmarks 
from orders o 
    inner join customers c on o.customrid = c.customerid 
    inner join lecturer l  on o.customrid = l.id 
    inner join student s   on o.customrid=s.studmarks;
