I wanted to JOIN all the three tables and form one table
for example if the Customer, Membership, and Personal_info table are Joined based on Cust_ID.
and condition,Even if Customer(Cust_ID,Fname,Mname,Lname) exists and does not have a Membership(Cust_ID,Membership_Level) or Personal_Info(Cust_ID,Height,Weight,Dieases)
should be shown in a table with NULL value.Here Cust_ID is a Primary Key in Customer Table and Foreign Key in Membership and Personal_Info. Go to the complete details ...
