Показать описание

In SQL, a view is an object on the database. It can help you simplify queries, improve security, allow for a layer of abstraction (leading to easier development), and more.
This video shows how to create a view in SQL and how to use it. The demonstration uses MySQL, but the SQL and concept also works in Oracle, SQL Server, and PostgreSQL (as well as other vendors that support views).

At first, I get lost when you say "Tyboos". Later I realized that you are talking about "Tables". Different accents are SO different in English just like the Chinese language. :D LOL

thanks for the demo, just a quick question, when people use Power BI or tableau, normally its connecting with the VIEW right ? If the tables are very big, does connect via the view = extracting all data of that(view, or table) from data warehouse and store them in laptop's memory ? that is why there are lots of performance issues ?

Can you still create views if you have read-only access in oracle?
