    I would like to add few more points on top of this tutorial.
    DML operations can't be performed if the view is created from more than one table.. Possibility is with instead of triggers...
    DML can't be done if the view has aggregate functions
    Set operators
    Check constraints
    Group by clause
    Having clause
    Etc etc...
    Row Id of the view and base table is same that's the reason when we query the view... data will be fetched from the base table.... Please add if I missed any other points

    @husenmobilesworld6482 3 года назад

    If you explain the quaries from beginning of creating tables(perticular concept) then it will be more clear, but you already created table so we don't know what data you given . Because of this it is bit hard to understand quaries.
    Please explain the examples like who needs some more information from you sir.
    It's very honour to see a guy like you to helping this video lots of people.

    Nice explanation.
    Below are few queries and concerns if you can add in you vedio
    1. Can you show how a DML operation using complex view fails.
    2. At the last minute you mentioned to provide few senario regarding view, could you please provide the same.
    Regards,

    hey, can't we just give the select query with where condition of fast sales(if not for security reason)...that will suffice and no need of view. So i want to know the real reason to use a view

    • @TechCoach
      @TechCoach  3 года назад +1

      Your view is made up after joining 5 tables and you only want to fetch the data from last 3 years , it will be much more clean to abstract the complex joins by using a simple view I hope that clarifies.
