SQL View - SQL Create View Statement - Views in SQL
SQL View
- In Microsoft SQL Server (MSSQL), a view is a virtual table that is based on the result of a SELECT query. Views allow you to simplify complex queries, encapsulate logic, and provide a consistent interface to the data stored in one or more tables. You can create, modify, and query views using SQL statements. Here's how to work with views in MSSQL:
Demo wikitechydatabase
- Below is a selection from the wikitechytable table used in the examples:
1. Creating a View:
- To create a view, you use the CREATE VIEW statement. Here's the basic syntax:
Syntax
CREATE VIEW view_name AS SELECT column1, column2, ... FROM table_name WHERE condition;
- view_name: The name of the view you want to create.
- column1, column2, ...: The columns you want to include in the view.
- table_name: The table(s) from which you want to retrieve data.
- condition (optional): A condition to filter the data.
Example
CREATE VIEW wikitechyview AS SELECT * FROM wikitechytable WHERE fees >= 50;
Output
2. Querying a View:
- Once a view is created, you can query it just like you would query a table.
Example
SELECT * FROM wikitechyview;
Output
3. Dropping a View:
- To remove a view from the database, you use the DROP VIEW statement.
Example
DROP VIEW wikitechyview;
