What is the difference between SQL views and tables?
An example of an AI chatbot conversation about SQL views and tables.
What is the difference between SQL views and tables?
SQL tables are physical storage structures that hold data, while views are virtual tables that display data from one or more tables.
Can you explain how views are created?
Views are created using the CREATE VIEW statement, which defines a query that selects data from tables.
Are there any performance differences between using views and tables?
Yes, views can sometimes improve performance by simplifying complex queries, but they may also add overhead depending on the database.
Can I update data through a view?
Yes, you can update data through a view, but it must be updatable, meaning it should be based on a single table without complex joins.
