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.
