Wie man 4 Tabellen in SQL verbindet

# no need to use parentheses - works fine
SELECT * FROM names A
INNER JOIN address B ON A.personID = B.personID
INNER JOIN emailAddress C ON A.personID = C.personID
INNER JOIN phoneNumbers D ON A.personID = D.personID;

Schließen Sie drei Tabellen SQL an

Suppose we are having three table named as 
Student_details
Attendance_details
Batch_details
And we have to apply join these three tables for fetching records

Example query:
select column_names
from Student_detail as s join Attendance_details as a on
s.s_id = a.s_id join Batch_details as b on 
s.s_id = b.s_id;

Here in the above example we implemented simple join but you change it with own join requirements.
