[@premgona5587]

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

[@TechCoach]

Thanks for adding the Information Prem.I will make another video series on trigger to explain the 1st point. I have a small request I am working on this new youtube channel. "An Indian Abroad" It will really help me if you watch and subscribe to it. kzbin.info/www/bejne/p2XIiayFhdVggtU

[@husenmobilesworld6482]

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.

[@ranajparida3902]

[@priyavarthinip874]

Could u pls give a real time scenario on investment banking domain

[@TechCoach]

Priyavarthini P Sure I shall make one soon.

[@Karsh.y]

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]

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.

[@Karsh.y]

@@TechCoach ya pretty much.... thanks , so in short it simplifies fetching the data.

[@TechCoach]

@@Karsh.y it does and you can limit the data access as well.you can provide access to views and not tables

[@Karsh.y]

@@TechCoach ohkay 😊 got it thanks a lot

[@Ganeshay-09]

How to download transaction script

[@deep54046]

You mentioned one point. Suppose i am creating a view with 450 million records, this is a huge replication we are doing and it will surely hamper the performance. So whats the solution to this?

[@TechCoach]

Views don't contain any data , materizaled view does. Can you please clarify your doubt again??

[@rampradeepkalivarapu7753]

check option is mising......

[@TechCoach]

Sure I will review it, I have a small request I am working on this new youtube channel " An Indian Abroad" it will really help me if you watch and subscribe to it. kzbin.info/www/bejne/fnO0eZihgpaIaMU

[@besttube2401]

U r wrong... While doing DML operations view does not execute.. it is just rename of query

[@AnIndianAbroadd]

Thanks for your input, I will look into it.
