    Dear all, based on my understanding.

    1) The purpose of create VIEW is to expetide query result right? (speed of result returned) what else?

    2) How can i handle duplicate column name 'customer_id'

    CREATE VIEW view_customer AS SELECT * FROM customer_master cm INNER JOIN customer_personal_profile cpp ON cm.customer_id = cpp.customer_id

    if duplicate the column name, you might manually to rename it.

    for example:

    select a.aaa as NameA, b.aaa as NameB from a inner join b on a.id=b.id
